A high-alkaline APC concentrate at pH 13 that lifts oil, grease and lubricants off workshop floors, out of the engine bay and off the lift in one pass. Not for pH-neutral coatings, synthetic-leather dashboards or anodised aluminium parts without a test patch first.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003eThe \u003cstrong\u003eKoch-Chemie Green Star Universal Cleaner\u003c\/strong\u003e works through a mix of surfactants, alkaline builders and corrosion inhibitors. With a pH between 12.5 and 13 it saponifies organic dirt — oil, grease, wax — turning it into soap compounds you can rinse off.\u003c\/p\u003e\n\n\u003cp\u003eThe surfactant shell then holds the loosened dirt in suspension so it doesn't dry back onto the panel when you rinse. That's why Green Star is the go-to APC in plenty of workshops and detailing shops that want a single cleaner for the engine bay, the lift, the workshop floor and exterior plastics — not because it's the best at any one of them, but because it hits the right balance between cleaning punch and material safety across that whole bracket.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-green-star-gs-universalreiniger_hero.png?v=1775995591\" alt=\"Koch-Chemie Green Star Gs bottle and canister on a concrete wall in front of a white Ferrari 296 GTB\" loading=\"lazy\" width=\"1200\"\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOne chemistry, four dilutions.\u003c\/strong\u003e The mix ratio decides the job: 1:5 for the workshop floor and heavily oiled engine bays, 1:10 as a wheel pre-cleaner and bug remover, 1:20 for exterior plastics and rubber care, 1:50 for routine maintenance cleans in the customer reception.

A second pass lifts the residual dirt that was still in the pore bed. You won't get there mechanically with a pH-neutral interior cleaner.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDetailing1's tip from the shop:\u003c\/strong\u003e Never hit warm or sun-heated surfaces — once an engine block is past about 40 °C the alkaline solution flashes off and leaves water marks and limescale rings on painted covers. Engine-bay sequence: let the vehicle cool, mask intake and electronics, work bottom-up at 1:10, give it three minutes max, then rinse generously with a soft jet from the \u003ca href=\"\/en\/collections\/universalreiniger\"\u003euniversal cleaner\u003c\/a\u003e group. For repeat jobs grab a foam sprayer — it lays the 1:10 solution down more evenly than any hand pump and buys you 40 to 60 extra seconds of dwell on vertical surfaces.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003e1 to 5. 1 to 20. One canister, four jobs.\u003c\/h3\u003e\n\u003cp\u003eWith the Koch-Chemie Green Star Universal Cleaner the cleaning power isn't in the bottle, it's in the mix ratio. Skip the difference and you'll either clean too soft or wreck the material.\u003c\/p\u003e\n\n\u003cp\u003eFor the workshop floor you mix 1:5 in warm water, lay it down with a scrubber or single-disc machine, give it three minutes and pick it up with a wet vac. For the lift and the engine bay 1:10 is the safe standard: it lifts oil reliably without going at rubber steering boots or wiring-loom sheaths. For exterior plastics, trim and badly soiled wheel arches 1:20 is enough. The 1:50 dilution is for routine maintenance cleans in customer reception or on tiled floors — at that point you're past \"APC\" and into a mild alkaline cleaner with residual grease-cutting power.\u003c\/p\u003e\n\n\u003cp\u003eThe mistake shops almost always make with Green Star is the same one: too strong a mix, because \"stronger is better\" is stuck in the head. In practice 1:5 on an engine block gives you no measurable edge over 1:10 — what you get instead is higher chemical burn and the risk of overloading the corrosion inhibitor on aluminium. The real lever is dwell time: three minutes instead of two. Two passes instead of one. Never crank the concentration if the first pass came up short.\u003c\/p\u003e\n\n\u003cp\u003eTwo practical dosing workflows hold up day to day. Workflow one: canister straight onto a dosing station at the water tap, ratio set through the Venturi nozzle, application by foam sprayer or pressure sprayer. Workflow two for smaller shops: two labelled 500-millilitre spray bottles, one with the 1:10 mix for engine bay and wheel arch, one with 1:20 for exterior plastics. Mix both fresh every day — alkaline working solutions lose cleaning power inside 24 hours because CO₂ from the air slowly drops the pH.\u003c\/p\u003e\n\n\u003cp\u003eAn 11-kilo canister at a properly mixed 1:10 covers about 110 litres of working solution — that's roughly 40 engine-bay cleans or 15 workshop-floor passes over 100 square metres. For shops running two lifts and regular detailing the 22-kilo or 225-kilo drum pays off from three cleans a week, purely on the per-kilo price difference.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-green-star-gs-universalreiniger_closeup.png?v=1775995596\" alt=\"Koch-Chemie Green Star Gs label close-up with the pH 12.5 marking visible\" loading=\"lazy\" width=\"1200\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eAlkaline. But not for everything.\u003c\/h3\u003e\n\u003cp\u003eThe Koch-Chemie Green Star Universal Cleaner has workshop DNA — it's not the right chemistry for delicate interior or coating surfaces.\u003c\/p\u003e\n\n\u003cp\u003eIt punches above its weight wherever organic dirt dominates: engine oil, gear oil, grease mist in the bay, soot on the workshop floor, brake-dust\/grease mixes in the wheel arches, road grime on commercial-vehicle frames. Bugs and bird droppings also soak off well with the 1:10 dilution before the actual wash. The alkaline pH saponifies the protein and turns a baked-on crust into a layer you can pull off — exactly where pH-neutral products would need you to scrub.\u003c\/p\u003e\n\n\u003cp\u003eWhere Green Star runs out of road is where the pH becomes the problem. On ceramic-coated paint every pass shaves a bit off the top bonding layer of the coating — for coating-sealed cars a pH-neutral shampoo or the Koch-Chemie \u003ca href=\"\/en\/products\/koch-chemie-mehrzweckreiniger-mzr-universalreiniger\"\u003eMultipurpose Cleaner \"Mzr\"\u003c\/a\u003e is the call.\u003c\/p\u003e\n\n\u003cp\u003eAnodised aluminium, matte aluminium and polished metal you never treat neat and you always patch-test in a hidden spot first. The corrosion inhibitor protects painted aluminium reliably, but on anodised surfaces it starts to struggle. Same goes for non-anodised magnesium rims and race parts — the alkaline side bites into the surface as soon as you push the dwell past two minutes.\u003c\/p\u003e\n\n\u003cp\u003eInside the cabin Green Star is plainly too aggressive: synthetic leather, Alcantara and coated dashboards don't take alkaline concentrates long-term, not even at 1:50. If you want one cleaner for both workshop and interior, that's a different chemistry.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-green-star-gs-universalreiniger_ergebnis.png?v=1775995602\" alt=\"Freshly cleaned Ferrari engine bay after a Koch-Chemie Green Star pass\" loading=\"lazy\" width=\"1200\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eGreen Star, Gs9 or Mzr. Your decision tree.\u003c\/h3\u003e\n\u003cp\u003eKoch-Chemie has three universal cleaners with overlapping use cases — the choice isn't about price, it's about what you're cleaning.\u003c\/p\u003e\n\n\u003cp\u003eThe classic Green Star is the workshop pick: hard-alkaline, high oil-carrying capacity, built for tough exterior and underbody work. The \u003ca href=\"\/en\/products\/koch-chemie-green-star-96-gs9-universalreiniger\"\u003eGreen Star 96 \"Gs9\"\u003c\/a\u003e is the milder follow-up with an optimised surfactant base and lower environmental load — it doesn't replace the classic Gs, it sits alongside it for detailers who work more often on private-customer cars with coatings and less on commercial frames. The Multipurpose Cleaner \"Mzr\" runs on completely different chemistry: weakly alkaline through to pH-neutral, built for interior, dashboards, carpets and upholstery. Gs cleans the engine bay, Mzr cleans the seats after.\u003c\/p\u003e\n\n\u003cp\u003ePractical rule for the buy decision: if the focus is the lift, the engine bay, the workshop floor and commercial-vehicle work, grab the classic Green Star in 11 or 22 kilos. If you mostly detail private-customer cars with ceramic protection and need the APC for wheel arches, bug removal and exterior plastics, the Gs9 is the cleaner fit. If you're after a cleaner for interior, carpet and upholstery, neither Gs nor Gs9 is the right answer — that's where the Mzr lives.\u003c\/p\u003e\n\n\u003cp\u003eFor the typical one-man detailer with a mixed customer base, the 11-kilo Green Star plus a 1-litre Mzr covers most of the actual workload: Gs for the whole exterior, the engine bay and floor cleans, Mzr for the interior. If you've got three separate APCs on the shelf — workshop cleaner, wheel cleaner, interior cleaner — this two-product setup halves the chemical cabinet and still cleans tighter.\u003c\/p\u003e\n\n\u003cp\u003ePack size tracks monthly throughput. The 1000-millilitre spray head is for the home detailer and the first test drive, not a working shop. From one vehicle a week with a proper exterior wash the 5-litre canister pays off; from three vehicles the 11-kilo container. 22 and 225 kilos belong in shops with a dosing station and steady commercial-vehicle work — for smaller outfits they're an unnecessary lock-in to one chemistry and harder to handle.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-green-star-gs-universalreiniger_detail.png?v=1775995607\" alt=\"Green Star working solution on the black plastic wheel arch of the Ferrari\" loading=\"lazy\" width=\"1200\"\u003e\u003c\/p\u003e","brand":"Koch-Chemie","offers":[{"title":"1000 ml \/ 1 liter","offer_id":48494630109519,"sku":"D1-KCX-291001","price":6.99,"currency_code":"EUR","in_stock":true},{"title":"2x 1000ml","offer_id":48725287960911,"sku":"D1-KCX-68037_2","price":13.7,"currency_code":"EUR","in_stock":true},{"title":"3x 1000ml","offer_id":48725287993679,"sku":"D1-KCX-68037_3","price":20.34,"currency_code":"EUR","in_stock":true},{"title":"5 liters","offer_id":48762352468303,"sku":"D1-KCX-291005","price":29.99,"currency_code":"EUR","in_stock":true},{"title":"11kg","offer_id":48494630142287,"sku":"D1-KCX-291011","price":56.49,"currency_code":"EUR","in_stock":true},{"title":"22kg","offer_id":49094546522447,"sku":"D1-KCX-291022","price":107.49,"currency_code":"EUR","in_stock":true},{"title":"225kg","offer_id":49094546555215,"sku":"D1-KCX-291225","price":1134.99,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-green-star-universalreiniger.jpg?v=1710769279"},{"product_id":"koch-chemie-gentle-snow-foam-gsf-reinigungsschaum","title":"Gentle Snow Foam \"Gsf\" Cleaning Foam","description":"\u003ch2 id=\"speakable-headline\"\u003epH-neutral pre-wash with the Koch-Chemie Gentle Snow Foam\u003c\/h2\u003e\n\n\u003cblockquote id=\"speakable-summary\"\u003e\n  \u003cp\u003e\u003cem\u003eWhat is the Koch-Chemie Gentle Snow Foam?

Tip more Gsf in but skimp on water and you get thin foam instead of a creamy blanket. Rule of thumb: fill the mixing bottle two-thirds with warm water, then dose 20 ml per litre. With soft water under 8 °dH bump the dose up a touch; with hard water from 14 °dH ease off — otherwise you end up with stringy foam that's a pain to rinse.\u003c\/p\u003e\n\n  \u003cp\u003eAnd always work onto wet, pre-rinsed paint. Dry paint means the foam grinds loose grit into the surface — the most common beginner mistake.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eFoam lance, 20 ml, let the foam sheet off\u003c\/h3\u003e\n\u003cp\u003eYou lay the Gsf down on a wet, pre-rinsed car — never on dry paint, or you'll drag loose grit across the surface when you rinse. Knock the heavy dirt, bugs and bird muck off with the pressure washer first. A quick clear-water rinse beforehand takes 30 seconds and saves the clear coat from needless swirls.\u003c\/p\u003e\n\n\u003cp\u003eInto the foam lance goes 20 ml of Gsf per litre of water, which is about 1:50. Lay the foam on bottom to top so the run-off doesn't draw clean streaks through the dirt. Let it dwell 4–6 minutes, shorter in the sun — the foam mustn't dry on, or it'll leave streaks.\u003c\/p\u003e\n\n\u003cp\u003eThen rinse top to bottom thoroughly with clear water. Foam left in the panel gaps points to too little water pressure or too short a rinse. Whatever's still on the paint after that belongs to the \u003ca href=\"\/en\/collections\/autoshampoo\"\u003ecar shampoo\u003c\/a\u003e step of the two-bucket wash. The pre-wash doesn't replace the shampoo, it just cuts down how much grit ends up in your wash mitt.\u003c\/p\u003e\n\n\u003cp\u003eIf you haven't got a foam lance on the pressure washer, you can put the Gsf on with a pump sprayer instead — the foam comes out a lot flatter there and doesn't last as long. For a manual bucket wash, dose 50 ml in 10 litres of water, about two pumps from a trigger bottle. That's comfortably enough foam for a mid-size car, anything from a Golf up to an E-Class.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-gentle-snow-foam-gsf-reinigungsschaum_anwendung.png?v=1778625656\" alt=\"Koch-Chemie Gentle Snow Foam Gsf – foam lance spraying thick cleaning foam onto the 911 Turbo S\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003epH-neutral means your coating stays put\u003c\/h3\u003e\n\u003cp\u003eThe biggest difference from active pre-wash foams like the \u003ca href=\"\/en\/products\/koch-chemie-green-star-universalreiniger\"\u003eKoch-Chemie Green Star\u003c\/a\u003e is the pH. Gsf sits at 7.5, Green Star at around 11. On uncoated paint that doesn't matter; on a ceramic coating it does.\u003c\/p\u003e\n\n\u003cp\u003eStudies and hands-on testing show it: strongly alkaline cleaners above pH 10 break down the topcoat of ceramic coatings measurably faster. If you want to get 12 or 24 months of life out of your coating, you're better off with a pH-neutral weekly wash. The Gsf is built for exactly that — ongoing care instead of a one-off deep clean. The coating's hydrophobic effect stays intact, and the water beads after the wash just like it did on day one.\u003c\/p\u003e\n\n\u003cp\u003eWhere the Gsf hits its limits: baked-on bugs on the front end, tar spots on the sills, brake dust on the wheels or hardened pollen — it won't shift those.

The logic is simple: clean gently and often rather than aggressively and rarely. If you make the wash a fixed weekly habit, the Gsf takes you furthest.\u003c\/p\u003e\n\n\u003cp\u003eIt's less of a fit for body shops, seasonal cars coming off a long lay-up, or the spring clean after winter — there active foams with a higher pH have the edge, because the dirt is long past what the Gsf can dissolve. And if you don't own a foam lance and only run a pressure sprayer, the Gsf will give you foam, but never the consistency and dwell time of a proper lance on a pressure washer. For that case a spray-on pre-cleaner makes more sense.\u003c\/p\u003e\n\n\u003cp\u003eThe 1-litre bottle covers around 50 washes, the 5-litre can 250. If you look after more than one car or work in a detailing studio, the 5-litre container runs about 30 percent cheaper per wash. Pair it with a pH-neutral shampoo like the Koch-Chemie Nanomagic Shampoo or GYEON Q² Bathe+ for the two-bucket wash, and a drying towel to finish, and you've got the full weekly workflow for a well-kept car — from the first jet of water to the last drop, without ever attacking your coating.\u003c\/p\u003e\n\n\u003cp\u003eThe signature cherry scent is a matter of taste, but it rarely divides opinion — most detailers find it a lot more pleasant than the soapy standard smell of many competitor products. In closed garages or wash bays the smell doesn't linger after rinsing, which is a handy detail in day-to-day use.\u003c\/p\u003e\n\n\u003cp\u003eFirst time you run the Gsf, don't be stingy with the dose. 20 ml per litre is the floor for a visible foam blanket. On really dirty cars or with hard tap water, go a pump higher. The extra 4–5 cents a wash is nothing next to a weaker result.\u003c\/p\u003e\n\n\u003cp\u003eSame goes for the water pressure at the washer: under 100 bar the foam stays thin; from 130 bar it turns creamy and sits thick on the paint. Running a Kärcher K7 or similar, you can crank the lance to maximum foam output. With portable battery washers the foam comes out noticeably flatter — not a product fault, just a question of pressure.\u003c\/p\u003e\n\n\u003cp\u003eOne more tip from what we see at Detailing1: before each seasonal wash in spring and autumn, swap the Gsf for an active-foam wash with Green Star. That way no pollen film and no winter salt gets a foothold — the kind the pH-neutral foam can't shift over time.

You spray it on as a pump mist over the pre-cleaned, still-wet engine bay, where it pushes out the residual water and cross-links after 6 to 8 hours into a dirt-repellent, wafer-thin layer. Unlike classic engine-shine sprays, Motorplast skips propellants and silicone, which is what clears it for use in body shops (no painter's fisheyes) and on Mercedes-Maybach models (official factory approval).\u003c\/p\u003e\n\n\u003cp\u003eThe look stays deliberately satin-matt rather than high-gloss — the surface keeps its original character, the protection is physically there without the engine looking like it has just been oiled up.

Lay down puddles instead of a fine mist and you stretch the drying time well past the usual 6 to 8 hours, the polymer cures unevenly and leaves milky edges or tacky spots. The clean routine: let the engine cool to hand-warm, pre-clean with \u003ca href=\"\/en\/products\/koch-chemie-green-star-gs-universalreiniger\"\u003eGreen Star\u003c\/a\u003e at 1:10, rinse off with a soft water jet, mist Motorplast thinly into the still-wet bay, close the bonnet and let it sit overnight. Tap any leftover pools the next morning with a dry microfibre cloth. It's self-levelling — no working in with a pad needed.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eSpray it on wet. Bonnet shut. Dry overnight.\u003c\/h3\u003e\n\n\u003cp\u003eYou spray Motorplast onto the pre-cleaned, still-wet engine bay because the residual water carries the polymers right into the tight gaps before the product itself pushes it back out. That's pro technique straight from the Daimler factory-norm test, not a marketing slogan.\u003c\/p\u003e\n\n\u003cp\u003eBefore you apply, let the engine cool down — hand-warm is ideal, boiling hot is not. On a block sitting at 130 °C oil temperature after a motorway run, the water-glycol-ether mix flashes off instantly and burns the polymers into the plastic as streaks. The officially approved heat window is 250 °C component temperature — that's for the cured film, not for the moment you apply it.\u003c\/p\u003e\n\n\u003cp\u003eFor a mid-size car, reckon on 50 to 200 ml. Work sparingly from about 20 cm away with the spray head and go systematically from back to front — valve cover, fuse box, then intake manifold, then the visible hoses and seals. You can reach awkward spots with a Cyclone or Tornador gun at 4 to 6 bar; in the home garage the supplied spray head does the job. Keep the mist away from open intake tracts and mass airflow sensors — those hot-wire sensors react badly to polymer coatings.\u003c\/p\u003e\n\n\u003cp\u003eOnce it's on, close the bonnet and let it sit 6 to 8 hours, ideally overnight. Day-one test: check the next morning whether any pools or drips are still holding. If so, tap them with a dry microfibre cloth — don't rub. The film is self-levelling and needs no mechanical spreading.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-motorplast-mp-motorkonservierung_anwendung.png?v=1777464474\" alt=\"Koch-Chemie Motorplast Mp being sprayed onto a wet engine bay Detailing1\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003ePlastic, rubber, ancillaries.

On these substrates the permanently elastic polymer film forms, holding off dirt build-up by months and slowing road-salt corrosion.\u003c\/p\u003e\n\n\u003cp\u003eThe hard limits are friction- and safety-critical. Drive belts, V-belts and pulleys are off-limits — the polymer layer cuts the grip friction, the belt slips and worst case the alternator drops out. For the same reason, keep it off brake components, brake disc faces and the pedals. On body paint, overspray leaves streaks and is pointless there anyway — Motorplast is no paint sealant. Any mist that lands on an inner wing or bumper edge, wipe it off straight away with a damp microfibre.\u003c\/p\u003e\n\n\u003cp\u003eIf too much product did end up in the bay and milky streaks have formed, a stripping routine with an alkaline cleaner sorts it: spray \u003ca href=\"\/en\/products\/koch-chemie-green-star-gs-universalreiniger\"\u003eGreen Star\u003c\/a\u003e on generously at 1:10, foam it up with a soft detailing brush, rinse off.

Twice a year is plenty.\u003c\/h3\u003e\n\n\u003cp\u003eThe typical rhythm for Motorplast is twice a year — once in spring after the salt season and once in autumn before winter sets in. In between, dusting the plastic covers with a microfibre cloth is enough. Detailing shops slot the product into their winter-check packages, because 5 minutes of work buys 6 months of corrosion protection.\u003c\/p\u003e\n\n\u003cp\u003eThe 500 ml spray bottle is the right call for a single car or for hobbyists getting seasonal vehicles like convertibles or classics ready for spring. Per treatment 50 to 100 ml — so the bottle carries you across several seasonal cycles. For multi-car households or commercial detailers the 5 litre canister pays off: noticeably lower price per litre, just decant it into a separate \u003ca href=\"\/en\/collections\/koch-chemie\"\u003eKoch-Chemie\u003c\/a\u003e cylinder bottle with a spray head. 20 and 200 litre containers are pure industrial variants for workshop groups and OEM supplier chains.\u003c\/p\u003e\n\n\u003cp\u003eStorage is fussier than with many other detailing products: Motorplast keeps at +5 °C to +25 °C, frost-free and out of the sun. Frost breaks down the polymer emulsion and the product won't spray cleanly afterwards. It's fine in the garage or the stockroom — just don't let it overwinter in the boot.\u003c\/p\u003e\n\n\u003cp\u003eApply Motorplast properly once — cold engine bay, wet pre-clean, thin mist, bonnet shut overnight — and you get an engine bay that looks the same after winter as it did before. That's the Detailing1 standard: not shine in the shop window, but an engine that still runs like new after three winters.

IPA is the industry standard for paint prep before sealants and coatings because it flashes off fast, leaves nothing behind and works broadly against non-polar stuff like waxes, silicone oils and polishing oils. The automotive-tuned formula is what makes the difference: the ingredients are matched to sensitive, high-gloss clearcoats — exactly the surfaces where too aggressive a degreaser could do microscopic damage.\u003c\/p\u003e\n\n\u003cp\u003eFor you, that means: you can use PPS straight after polishing without the alcohol base attacking freshly worked clearcoats. The alcohol is volatile, so the moment you've wiped it down the surface is ready for the next step. For the \u003ca href=\"https:\/\/detailing1.de\/products\/koch-chemie-ceramic-allround-c0-02-keramikversiegelung\"\u003eCeramic Allround C0.02 ceramic sealant\u003c\/a\u003e, PPS is the prep step we recommend: only on a fully grease-free surface can the ceramic polymer get maximum bite, and with it the full protection window of up to 24 months.\u003c\/p\u003e\n\n\u003ch3\u003ePPS as an inspection spray in the polishing workflow — catch holograms and scratches for sure\u003c\/h3\u003e\n\n\u003cp\u003eIn pro paint correction, the inspection job of PPS matters at least as much as the degreasing. The principle: polishing oils have a filling effect — they sit in fine surface defects and make them vanish under normal light. Only once an IPA degreaser pulls those oils off completely does the clearcoat show its true state. Skip this step and you risk laying a ceramic sealant or a wax over holograms and fine scratches — the defects get sealed in and stay visible for good.\u003c\/p\u003e\n\n\u003cp\u003eDay-to-day, you spray PPS onto the worked panel after each polishing pass and wipe it straight off with a clean, dry microfibre cloth. For the sharpest check, look the panel over under a cold light source or detailing LED right after the wipe — that's when even very fine holograms read clearly. If the panel still shows defects after the PPS check, you put in another correction pass; if it's flawless, you can go straight to the sealant.\u003c\/p\u003e\n\n\u003cblockquote class=\"rte panel\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDetailing1's tip from the shop:\u003c\/strong\u003e always grab a fresh, clean microfibre cloth for the PPS check — never the one you just polished with. Polishing-oil residue in the cloth would throw the check off. Day-to-day we'd reach for a short-pile, tightly woven microfibre polishing cloth. After the wipe, judge the panel right away under an LED hand lamp at a low angle — it shows holograms far sharper than normal room light.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003ch3\u003eWhere to use it and what it plays nice with — paint, plastic, metal and wheels\u003c\/h3\u003e\n\n\u003cp\u003eThe Koch-Chemie PPS isn't limited to automotive paint. The gentle formula means you can use it on every smooth surface on the vehicle: clearcoat and base coat, uncoated and coated plastic, metal (e.g. chrome, aluminium), wheel faces and glass are all fair game. For motorcycles, commercial vehicles and motorhomes the same rules apply.\u003c\/p\u003e\n\n\u003cp\u003eOne important limit: PPS is no all-purpose cleaner and no substitute for a proper pre-wash. It pulls polishing oils and light wax residue off already-cleaned surfaces — but not dried-on tar, bug splatter or brake dust. Those need their own dedicated products; only after that does PPS come in as the final degrease.\u003c\/p\u003e\n\n\u003ch3\u003ePPS vs the rest: when does hardware-store IPA do the job, when do you need the Koch-Chemie PPS?\u003c\/h3\u003e\n\n\u003cp\u003ePlain isopropyl from the hardware store works for plenty of jobs — but it's often too concentrated for freshly polished, sensitive clearcoats. The Koch-Chemie PPS is built specifically for paint prep: the right concentration, maximum compatibility on clearcoat and a handy spray system for precise dosing. If you're working a high-end vehicle or degreasing after heavy machine polishing, PPS keeps you on the safer side. On top of that, PPS gives you the double duty as an inspection spray that plain hardware-store IPA doesn't. The 5-litre size is ideal for pros and workshops doing several vehicles a day.\u003c\/p\u003e\n\n\u003ch3\u003eWho is the Koch-Chemie Panel Preparation Spray PPS right for?\u003c\/h3\u003e\n\n\u003cp\u003ePPS makes sense for anyone prepping paint properly and then laying a protective layer on top.

With the new version Koch-Chemie improved two things above all: colour depth and how easily it wipes off. That sounds like small tweaks, but day-to-day it makes a real difference: better colour depth means dark paint looks richer and deeper after the job — and with no extra work.

That bleeds the now-exposed iron particles out purple. What we see day-to-day: detailers treat this 1-2 punch as standard for lease returns with baked-on wheels.

Hot brake discs radiate well past 200 °C — if the cleaner hits that heat, the water in the dilution flashes off in seconds and you're left with highly concentrated potassium hydroxide standing on the paint, eating into the clear coat. Wait at least 15 minutes after parking up and wet it down generously.\u003c\/p\u003e\n\n\u003cp\u003eThe dilution follows the level of dirt: 1:10 is enough for weekly upkeep, 1:5 is the all-round figure for normal brake dust after two to four weeks of driving, 1:2 stays reserved for the extreme crusts on workshop vehicles. A pump sprayer with a foam nozzle like the \u003ca href=\"\/en\/products\/koch-chemie-foamer-bottle-schaumspender-150ml\"\u003eKoch-Chemie Foamer Bottle\u003c\/a\u003e or an iK Foam sprayer lays the solution down as a sticky wet foam that clings to the barrel and doesn't run off. On rougher wheels you can go over it with a soft wheel brush after 30 seconds — spread it, don't scrub.\u003c\/p\u003e\n\n\u003cp\u003eDwell time 1 to 3 minutes, 5 minutes max at the weakest dilution. Longer does nothing: Awh isn't about reaction time, it's about chemistry. Leave it on too long and all you risk is drying-in, and dry edges on the clear coat are the result. If a spot isn't clean, top up the dose — don't let it dwell longer.\u003c\/p\u003e\n\n\u003cp\u003eFinish with a strong pressure jet top to bottom. Rinse the barrel and the spoke edges in a controlled way until no foamy veil runs off any more. Cold rinse water is a must: warm water speeds up drying-in inside the barrel, and a leftover cleaner film later pulls into the clear coat as a run mark. On the tyre sidewalls you can put the Awh straight to use — it lifts the brown antioxidant bloom (tyre-rubber blooming) at the same time and saves you the separate tyre cleaner.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-alkali-wheel-cleaner-awh-felgenreiniger-alkalisch_anwendung.png?v=1778768219\" alt=\"Daniel spraying Koch-Chemie Alkali Wheel Cleaner Awh 1:5 from the iK Foam Pro 2 Alk onto the wheel barrel\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eSteel and painted aluminium yes, polished wheels no\u003c\/h3\u003e\n\n\u003cp\u003eAwh is cleared for standard steel wheels and alkali-resistant painted or powder-coated OEM aluminium wheels. As long as an intact clear coat protects the aluminium, the wheel behaves like perfectly normal paint and takes the cleaner with no trouble. That covers the vast bulk of the cars that sit on the lift at workshops and detailers every day — from lease returns to company cars.\u003c\/p\u003e\n\n\u003cp\u003eWhat Awh won't tolerate: raw aluminium, high-gloss polished aluminium, anodised wheels, magnesium wheels, uncoated forged wheels and chrome. On these surfaces the potassium hydroxide reacts with the metal in seconds. It oxidises the surface and leaves a milky, deeply etched patch — what's known as alkali burn.\u003c\/p\u003e\n\n\u003cp\u003eThis damage can't be washed off. The wheel is only saveable with hours of machine polishing at a specialist shop, and that runs into several hundred euros fast. In plain terms: on expensive multi-piece BBS RS wheels, on Porsche Fuchs wheels, on uncoated OZ forged wheels and on chrome lips, the sprayer stays in your hand. If you're not sure whether the wheel is anodised or painted, ask the manufacturer or test on an inconspicuous spot.\u003c\/p\u003e\n\n\u003cp\u003eFor exactly these sensitive wheel types, the pH-neutral \u003ca href=\"\/en\/products\/koch-chemie-magic-wheel-cleaner-mwc-felgenreiniger\"\u003eMagic Wheel Cleaner \"Mwc\"\u003c\/a\u003e or the reactive \u003ca href=\"\/en\/products\/koch-chemie-reactive-wheel-cleaner-felgenreiniger-750ml\"\u003eReactive Wheel Cleaner\u003c\/a\u003e is the right call. They bind the iron particles chemically and don't attack the aluminium.\u003c\/p\u003e\n\n\u003cp\u003eRule of thumb for switching between wheel types: Awh for steel and painted OEM alloy. Mwc or Reactive Wheel Cleaner for polished, anodised or chrome. If you need maximum bite on very robust steel wheels, reach for the acidic \u003ca href=\"\/en\/products\/koch-chemie-triple-acid-star-ta-felgenreiniger\"\u003eTriple Acid Star \"Ta\"\u003c\/a\u003e. That's a different category with its own risks, but the right answer for neglected winter wheels with no aluminium in the mix.\u003c\/p\u003e\n\n\u003cp\u003eOne more mix-up we'll clear up right here: at Koch-Chemie the abbreviation \"Awc\" doesn't stand for an acidic wheel cleaner, it stands for the Allround Window Cleaner — a glass cleaner, in other words.

A 1-litre spray bottle for the home garage is something Koch-Chemie deliberately doesn't carry under this code. The cleaner is built for continuous use and dilution logic, not for the weekend detailer with one car in the underground car park.\u003c\/p\u003e\n\n\u003cp\u003eOn consumption the dilution in a foam sprayer pays for itself directly.

Detailers with high daily throughput, rental-car fleet cleaning, hauliers running their own fleet care. For the keen hobby detailer, Awh is usually overkill. Here \u003ca href=\"\/en\/collections\/felgenreiniger\"\u003epH-neutral wheel cleaners\u003c\/a\u003e like Mwc, Reactive Wheel Cleaner or Sonax FelgenBeast are the more honest choice.\u003c\/p\u003e\n\n\u003cp\u003eThe one trick the manufacturer doesn't push hard: Awh doubles as a first-rate tyre cleaner.

The SiO₂ component is still wet on the paint right after the rinse — it needs the mechanical pressure of a soft drying towel to spread evenly and bond. Without that wipe step you get water spots instead of gloss. So plan an extra 5–10 minutes for a \u003ca href=\"\/en\/products\/soft99-max-wash-4pockets-trockenhandtuch\"\u003elarge microfibre drying towel\u003c\/a\u003e and work section by section.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003ePre-rinsed. Two buckets. One layer.\u003c\/h3\u003e\n\u003cp\u003eThe Ces gives its best result with the two-bucket method: a wash bucket with 50 ml of Ces to 10 l of warm water, a separate rinse bucket with clean water, and a high-pile \u003ca href=\"\/en\/products\/koch-chemie-microfaser-handschuh-set-oktopus-waschhandschuh\"\u003emicrofibre wash mitt\u003c\/a\u003e. The second bucket keeps the dirt out of the wash bucket — that protects the paint from wash marks and makes sure every section gets worked with a clean foam concentration. Skip the second bucket and you drag the coarsest dirt particles over the paint again and again, picking up the swirls the Ces can no longer level out.\u003c\/p\u003e\n\n\u003cp\u003eAlways pre-rinse before the shampoo. A pressure washer or garden hose flushes off loose sand and road salt. Skip it and you drag the coarse particles across the paint with the mitt and pick up micro-scratches.\u003c\/p\u003e\n\n\u003cp\u003eWith heavy soiling or a layer of bugs, run a pre-cleaner as snow foam first, otherwise the Ces works past its care component. Cars with baked-on pollen or Saharan dust need that pre-clean, no way around it.\u003c\/p\u003e\n\n\u003cp\u003eAlways work on shaded, cool paint — not in the sun, not on a warm bonnet. Otherwise the foam dries on, leaves water spots, and the sealant effect builds up unevenly. Top to bottom, section by section, rinse each section on its own — the polymer film only forms during the rinse.\u003c\/p\u003e\n\n\u003cp\u003eThat's the key difference from pure cleaning shampoos: with those it doesn't matter how long the foam sits on the paint, with the Ces the result stands or falls on rinsing each section quickly. Foam the whole car and rinse only at the end, and you give away most of the sealant effect and get nothing but a standard cleaning result.\u003c\/p\u003e\n\n\u003cp\u003eOne last thing to dial in is the water temperature. Lukewarm water between 25 and 35 °C activates the SiO₂ component better than cold tap water, the foam builds faster and the care film bonds more evenly. With ice-cold water in winter the paint does feel clean after the wash, but the full hydrophobic potential goes unused — better to mix in a bucket of hot water until the mix is hand-warm.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-ceramic-effect-shampoo-ces-autoshampoo-versiegelung_anwendung.png?v=1778625630\" alt=\"Koch-Chemie Ceramic Effect Shampoo \" ces maintenance shampoo sealant two-bucket-w loading=\"lazy\" style=\"width:100%;height:auto;border-radius:8px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eA care booster with clear limits\u003c\/h3\u003e\n\u003cp\u003eThe Ces is Detailing1's first pick as a maintenance shampoo for cars that are already coated — not as a sealant replacement. If you've never laid down a coating, the Ces still gives you a real, visible hydrophobic effect. If you already run a ceramic coating, every wash extends its lifespan by a few weeks, because the SiO₂ care component feeds the original sealant instead of degrading it.\u003c\/p\u003e\n\n\u003cp\u003eThe day-to-day reports are strong: on freshly waxed or coated paint the first wash brings a noticeably richer depth of gloss, with water beading off in 3–5 mm drops. Verified buyers at Trusted Shops regularly mention a visible beading effect and a pleasant berry-almond scent — a rarity from a pro-grade maker like Koch-Chemie.\u003c\/p\u003e\n\n\u003cp\u003eHonest about the limits: on unwaxed, uncoated paint the sealant effect lasts about 2–4 weeks, depending on the weather. In constant rain or with road salt in winter, shorter. If you want a permanent coating with 12+ months of lifespan, there's no getting around a proper ceramic coating. If you want to maintain and refresh in between, the Ces is the right call.\u003c\/p\u003e\n\n\u003cp\u003eIf you already have an older coating that's slowly getting tired, reach for the specialised \u003ca href=\"\/en\/products\/koch-chemie-reactivation-shampoo-rs-auto-shampoo-keramikversiegelung\"\u003eKoch-Chemie Reactivation Shampoo\u003c\/a\u003e — it reactivates the SiO₂ bond more deliberately than the Ces. And if you're washing the car right before applying a coating, don't reach for the Ces: the polymer film gets in the way of the new sealant bonding. For that, a neutral prep shampoo with no care component is the right choice, otherwise the prep work was for nothing.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-ceramic-effect-shampoo-ces-autoshampoo-versiegelung_ergebnis.png?v=1778625636\" alt=\"Koch-Chemie Ceramic Effect Shampoo \" ces maintenance shampoo sealant beading effect on paint loading=\"lazy\" style=\"width:100%;height:auto;border-radius:8px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eWho the Ces pays off for\u003c\/h3\u003e\n\u003cp\u003eThe Ces is the right call for car owners who wash every 1–2 weeks, want a clean finish, but don't want to wax or coat on a regular basis. You put in 20–30 minutes per wash and get a result that comes surprisingly close to a heavily polished show car — without the polishing step. Especially relevant for high-mileage city drivers, commuters with an underground parking spot, and anyone with a coated car who wants to actively extend its lifespan.\u003c\/p\u003e\n\n\u003cp\u003eLess suited is the Ces for workshops and detailers where pure cleaning power is the priority. For that, the Koch-Chemie Aktivwäsche AW is the stronger pick, because the Ces hits its limits faster with deeply worked-in brake dust and bug splatter.\u003c\/p\u003e\n\n\u003cp\u003eAs a complete wash workflow for this crowd it looks like this: pre-rinse with a pressure washer, snow foam for the pre-clean if needed, then a two-bucket wash with the Ces. After that, take it off section by section with the \u003ca href=\"\/en\/products\/soft99-max-wash-4pockets-trockenhandtuch\"\u003eSoft99 Max Wash drying towel\u003c\/a\u003e — no air-drying.\u003c\/p\u003e\n\n\u003cp\u003eOn the 1L versions, Detailing1 also offers the bundle with a dosing cap — it saves time on the weekly wash and prevents over-dosing. That's the most common mistake with the Ces day-to-day: more shampoo doesn't get you a better effect, just double the consumption.\u003c\/p\u003e\n\n\u003cp\u003eFor high-mileage drivers and multi-car households, the 5L container pays off after roughly 80 washes, because the per-litre price there runs about 30% below the 1L bottle. Wash weekly and it lasts you a good two years, with the extra cost earned back inside half a year.\u003c\/p\u003e\n\n\u003cp\u003eOne last Detailing1 insight for this crowd: the Ces gets better over time. On the first run on unwaxed paint the hydrophobic effect is visible but moderate. From the third or fourth wash a denser polymer film layers on, coat by coat.\u003c\/p\u003e\n\n\u003cp\u003eSuddenly water beads off in a normal summer rain as if the car had just been given a spray sealant. That's the point where most buyers switch to the Ces and never give it up — no miracle worker the first time, but a reliable build-up effect across the season.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-ceramic-effect-shampoo-ces-autoshampoo-versiegelung_lineup_8212300c-f401-47e5-ba76-e085ed4a6ee6.png?v=1778657751\" alt=\"Koch-Chemie Ceramic Effect Shampoo \" ces maintenance shampoo sealant litre and loading=\"lazy\" style=\"width:100%;height:auto;border-radius:8px;\"\u003e\u003c\/p\u003e\n","brand":"Koch-Chemie","offers":[{"title":"1000 ml \/ 1 liter","offer_id":49670904578383,"sku":"D1-KCX-811001","price":28.49,"currency_code":"EUR","in_stock":true},{"title":"1000ml + Dosing Cap","offer_id":54599151452495,"sku":"D1-KCX-811001+9998149","price":34.48,"currency_code":"EUR","in_stock":true},{"title":"2x 1000ml","offer_id":49670904611151,"sku":"D1-KCX-811001_2","price":57.8,"currency_code":"EUR","in_stock":true},{"title":"3x 1000ml","offer_id":49670904643919,"sku":"D1-KCX-811001_3","price":85.82,"currency_code":"EUR","in_stock":true},{"title":"5 liters","offer_id":49670904676687,"sku":"D1-KCX-811005","price":125.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-ceramic-effect-shampoo-ces-autoshampoo-versiegelung_d86bb773-4597-45d8-ad20-b521d3e869a4.png?v=1778623457"},{"product_id":"koch-chemie-rapid-rinseless-wash-rrw-waschen-ohne-abspuehlen","title":"Rapid Rinseless Wash \"Rrw\" — Rinseless Car Wash","description":"\u003ch2\u003eRinseless washing with Koch-Chemie Rapid Rinseless Wash \"Rrw\"\u003c\/h2\u003e\n\u003cp\u003eGet a fast, proper clean with the \u003cstrong\u003eKoch-Chemie Rapid Rinseless Wash \"Rrw\".\u003c\/strong\u003e This clever wash lets you clean your car top to bottom without rinsing off afterwards.

The care layer then sits on top of the dirt instead of lifting it, the surface looks fresh but pulls dust back in twice as fast within a few days. Degrease with APC first, wipe it dry, then spray. That way the care bonds with the plastic, not with the grime layer on top of it.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eNeat for high gloss. 1:4 for the original look.\u003c\/h3\u003e\n\u003cp\u003eYou apply Hydro Plast Care neat to tyre sidewalls and glossy exterior parts. Diluted at 1:4 it gives the matte original look for dashboards and door trims.\u003c\/p\u003e\n\n\u003cp\u003eThe dosing sets the gloss level, not how much you put on. The concentrate goes into an empty spray bottle or onto a clean sponge. Lay it down thin and even on the dry, degreased surface, let it flash off for 2 to 3 minutes and buff out with a microfibre cloth.\u003c\/p\u003e\n\n\u003cp\u003ePer car interior you'll work out around 20 to 30 millilitres at 1:4, and for neat application on four tyre sidewalls 30 to 40 millilitres covers the full set. For door seals and rubber profiles you go 1:1 and apply with an applicator brush, that keeps them supple without any shine.\u003c\/p\u003e\n\n\u003cp\u003eFor the cockpit we'd suggest 1:3 or 1:4, so the light doesn't bounce up into the windscreen and the dash doesn't look freshly oiled from the driver's seat. On bumpers and trim strips in matte plastic you work at 1:2. If you're prepping tyres for a photo shoot, apply neat to the dry sidewall and leave it for 5 minutes, no working in needed. You'll find the kit to go with it in the \u003ca href=\"\/en\/collections\/kunststoffpflege\"\u003ePlastic Care category\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003cp\u003eMix the amount you need for the day fresh, not in advance. A diluted solution in an open spray bottle pulls in air after 5 to 7 days and loses gloss, because the surfactant structure slowly separates out. For commercial use, write the mixing date on the bottle with a waterproof marker and bin the leftovers after a week, that's cleaner than the \"give it another good shake\" approach.\u003c\/p\u003e\n\n\u003cp\u003eFor the order in the workflow: vacuum the interior first, then degrease, then apply Hydro Plast Care. Outside it goes on after the wash and before the tyre care. If you do the tyre care first and then treat the bumper next to it with the gloss coat, you risk overspray on tyre sidewalls that haven't dried off yet, the result is patchy and won't just wipe back to right.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-hydro-plast-care-hpc-kunststoffpflegekonzentrat-wassserverduennbar_anwendung_f49ebe99-a6d7-4a04-89f7-a56830465279.png?v=1778657765\" alt=\"Koch-Chemie Hydro Plast Care applied to a cockpit with a microfibre cloth\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eSolvent-free means UV protection without the chemical smell.\u003c\/h3\u003e\n\u003cp\u003eHydro Plast Care lays a thin, flexible film as a UV barrier over the plastic.

Under that load the plasticisers migrate to the surface and get broken down by UV, the plastic goes grey, rough and starts to creak. The care layer from Hydro Plast Care doesn't replace those lost plasticisers, but it slows the UV reaction down.\u003c\/p\u003e\n\n\u003cp\u003eBecause the formula does without classic solvents, no aggressive fumes evaporate as you apply it. The product is cleared for the interior, no smell to deal with on the first drive home and no irritation for people who react to volatile hydrocarbons. The protective layer cuts the static charge on smooth plastic surfaces noticeably, which slows how fast dust settles between care intervals.\u003c\/p\u003e\n\n\u003cp\u003eThe clear limits: Hydro Plast Care isn't meant for leather, Koch-Chemie has its own products for that with Pol Star \"Po\" and Leather Star \"Ls\".

In that case a ready-dosed product from our \u003ca href=\"\/en\/collections\/koch-chemie\"\u003eKoch-Chemie category\u003c\/a\u003e is the smarter buy.\u003c\/p\u003e\n\n\u003cp\u003eA verified customer review of the 5-litre canister puts this honestly: if you're used to the Klassik version ready-to-use, the dilution step feels like extra work, and for that type of user Plast Star \"Pss\" is the better fit, not the concentrate. A second voice from the 1-litre bottle, by contrast, makes a point of the yield. Both bits of feedback show the same thing: the dilution curve isn't a blanket upside, it's a way of working that has to fit your workflow.\u003c\/p\u003e\n\n\u003cp\u003eThe four pack sizes cover different use profiles. The 1-litre bottle is the way in for one car and gives you around 5 litres of ready-to-use care after 1:4 dilution, enough for 25 to 30 cockpit passes. The 2×1-litre set and the 3×1-litre set are meant as a stash for detailing enthusiasts who run the family car, the second car and the seasonal car side by side.\u003c\/p\u003e\n\n\u003cp\u003eThe 5-litre canister is clearly worked out for detailers, workshops and fleet care and pulls the per-litre price down noticeably, at full 1:4 dilution it works out to 25 litres of ready care. If you're emptying the canister commercially, fill the spray bottle up front with the amount you need for the day and reseal the main container straight away, so the emulsion doesn't pull in air for nothing.\u003c\/p\u003e\n\n\u003cp\u003eOur strongest hands-on insight from our own details: applying Hydro Plast Care straight after the wash onto lightly damp-wiped plastic saves you a whole step compared to solvent-based classic care. The water-dilutable concentrate spreads more evenly on a damp surface, as long as the surface is degreased and not dripping wet.\u003c\/p\u003e\n\n\u003cp\u003eStore frost-free between 5 and 30 °C and use it up within 24 months of opening, that way the emulsion stays stable and you hold the set gloss level for the whole life of the container.

The active ingredient is an amino-functional polysiloxane — in plain terms, a flexible silicone polymer with two different ends. One end carries nitrogen anchors (amino groups), the other water-repellent methyl groups. On wet paint the polymer lines itself up on its own: anchors into the clear coat, methyl ends facing out. What that means for you: the water beads straight off in tight little balls instead of clinging to the paint — no carnauba wax, no silicon dioxide like a ceramic coating, just a self-aligner that holds for three to six weeks.\u003c\/p\u003e\n\n\u003cp\u003eDetailers call this workflow \"spray-on, rinse-off\": spray it on, rinse it off, done. You lay the WetGloss down section by section on the wet car right after rinsing off the shampoo, the pressure washer spreads the polymer evenly across the section in seconds, and the excess runs off with the rinse water. Drying with the microfibre towel is the only moment you still touch the paint. Handy: it works as a standalone sealing step between full details — and as a topper over existing ceramic or wax coatings, freshening the hydrophobics so you can hear it and visibly tightening up the way water beads off.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-wet-gloss-wg-nassversiegelung_hero.png?v=1778700765\" alt=\"Applying Koch-Chemie WetGloss Wg 500 ml on a black Porsche 911\" loading=\"lazy\" style=\"max-width:100%;height:auto;\"\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBeading refresh in minutes.\u003c\/strong\u003e Straight after the rinse, water beads off the paint in tight, compact drops instead of forming a flat film — that classic showroom-fresh effect.

The 500 ml spray bottle covers three to five mid-size cars when you work section by section — about 2.30 to 5.10 euros per seal.

What that means for you: the whole sealing step fits into a single bay slot at the self-service wash.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDay-to-day from Detailing1:\u003c\/strong\u003e The costliest mistake with the WetGloss is letting it flash off on paint that's too warm. Once a panel hits roughly 30 to 40 degrees — which dark paint reaches within minutes in May sunshine — the alcohol carrier solvent (2-propanol, technically) evaporates so fast that the polymer cross-links unevenly. In plain terms: the amino-functional polysiloxane only grabs the paint in patches and leaves white streaks or water spots in the bits it didn't cover. Worst case you have to pull the residue off with an alkaline cleaner or even a light machine polish — half an hour of extra work the application was meant to save you. So always work in the shade, on a cool body under 25 degrees and section by section: spray the bonnet, rinse it straight away, then move to the next section. The pressure washer is a must. Its hard jet drops the consumption from the 250 millilitres the maker quotes defensively to a realistic 100 to 150 millilitres per mid-size car.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eApplying WetGloss properly: wet paint, section, high pressure\u003c\/h3\u003e\n\n\u003cp\u003eYou spray the Koch-Chemie WetGloss section by section onto the wet car right after the wash, rinse straight away with high pressure and dry with the microfibre towel. Three steps, no buffing.\u003c\/p\u003e\n\n\u003cp\u003eThe running order in practice: car pre-washed, foam rinsed off, body still dripping wet. You grab the spray bottle, give it a quick shake and work in sections — half the roof, one wing, one door area. Six to eight pumps per section is plenty, no flooding it. Straight after, rinse off with the pressure washer from about 30 centimetres, top to bottom, until the water rolls off in tight drops and no foam streaks run down any more. Only then move to the next section.\u003c\/p\u003e\n\n\u003cp\u003eThe rinse pressure makes or breaks the result. A plain garden hose won't cut it: the polymer won't spread evenly and you'll burn through twice as much for half the result. You want over 100 bar, the kind every self-service wash box delivers. With hard tap water, dry straight after the final rinse — leftover water otherwise leaves limescale spots on the freshly sealed surface.\u003c\/p\u003e\n\n\u003cp\u003eFor drying, a soft microfibre drying towel pulled across in sections does the job.

If you want to take out scratches or buff away holograms, you're in the wrong place.\u003c\/p\u003e\n\n\u003cp\u003eThe clear no-go substrates. Matte paint and matte wraps get optically smoothed over by the polymer, leaving an unwanted greasy look — the maker rules this use out explicitly, and the only way back out of that effect is an alkaline cleaner. Fabric soft tops soak the emulsion up unevenly and stiffen the fibres; there are dedicated textile sealants for those. Fresh paintwork under 30 days old needs time to off-gas — a seal on top can slow the curing and, worst case, lead to clouding. Bare polished aluminium can streak depending on the alloy, because the raw metal binds the polymer's nitrogen anchors differently than a closed clear coat.\u003c\/p\u003e\n\n\u003cp\u003eThe second, less well-known behaviour is the masking effect: lay WetGloss over an existing ceramic coating with pronounced sheeting behaviour — that is, water rolling off flat rather than forming drops — and for three to six weeks the polymer takes over the water behaviour of the seal. Your SiO₂ coating's flat sheeting turns into beading. In practice: the coating isn't harmed, and once the sacrificial layer washes off the original behaviour comes back. But if you've only just had a premium coating built up, be aware of the temporary change in character and use it more as a winter refresh.\u003c\/p\u003e\n\n\u003cp\u003eThe choice logic within the Koch-Chemie range. If you want a touch-free refresh in minutes between washes → WetGloss.

After the regular hand wash you reach for the spray bottle, six pumps per section, rinse, dry — five minutes of extra work for four to six weeks of measurable hydrophobicity.\u003c\/p\u003e\n\n\u003cp\u003eIt's especially economical in a multi-car household and in small commercial use. At a realistic consumption of 100 to 150 millilitres, the 5-litre container covers more than 33 seals. Run the WetGloss alongside a regular foam pre-wash and you stretch the effective durability even further, because the polymer doesn't have to break down any heavy crust and can build cleanly onto a well-kept surface.\u003c\/p\u003e\n\n\u003cp\u003eThe WetGloss is less suited to reconditioners with a snow foam lance who have to run bigger fleets touch-free — there the concentrated Hydro Foam Sealant S0.03 wins on cost per application. And for paint-shop handovers with fresh repair paintwork, the 30-day waiting window applies, no exceptions.\u003c\/p\u003e\n\n\u003cp\u003eThe one trick the maker doesn't say out loud: don't spray the whole car at once. Lay one section down, pull the water film over it straight away with high pressure, then on to the next. In plain terms: the polymer only needs the seconds in which the hard jet pushes the material across the wet panel — that's exactly where the cross-linking happens, before the alcohol carrier solvent evaporates and can leave streaks.

The emulsion-like consistency throws clouds, streaks and overspray onto glass and rubber. What we see day-to-day: put 1 to 2 sprays onto a short-pile microfibre, then lay it down in a cross pattern. Horizontal first, then vertical, with overlapping passes.\u003c\/p\u003e\n  \u003cp\u003eAt 18 to 22 degrees Celsius the product hazes up after 1 to 3 minutes. Pros call it \"hazing\" — the surface visibly dulls as the carrier flashes off. Only then buff it off streak-free with a clean side of the cloth. For the next 24 hours keep water, washing and moisture away. The polymers need that time to cross-link, otherwise the layer partly breaks down in the next rain.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003ePfs on dry paint in a cross pattern\u003c\/h3\u003e\n\n\u003cp\u003eThe PerfectFinish Sealant works differently from a quick detailer. It needs dry, clean, grease-free paint, otherwise the polymer chains won't grab. The full workflow from pre-wash to sealing takes about 90 minutes on a mid-size car.\u003c\/p\u003e\n\n\u003cp\u003eThe steps: touchless pre-wash with snow foam, then a manual two-bucket wash with pH-neutral shampoo, then dry thoroughly. Ideally with a blower, so no leftover water runs out of door shuts or panel gaps. If you mix the Pfs up with the in-house Hydro Foam Sealant \"S0.03\", you'll be let down: the S0.03 is a wet sealant applied through the foam lance, the Pfs needs it bone dry.\u003c\/p\u003e\n\n\u003cp\u003eBefore you apply, degrease the paint with a panel-prep spray — that's the step hobby users skip most. Only grease-free paint lets the polymers grab; otherwise you get a nice look for three days and then nothing.\u003c\/p\u003e\n\n\u003cp\u003eApply in a cross pattern — horizontal and vertical with overlapping passes over the microfibre. Let it flash off for 1 to 3 minutes, then buff with a fresh side of the cloth. In warm weather above 22 degrees the window shrinks to 60 to 90 seconds; then work panel by panel instead of the whole car. Never use it in direct sun — the product dries before it reacts and leaves visible smears.\u003c\/p\u003e\n\n\u003cp\u003eFor machine use Koch-Chemie clears 1,000 OPM max: minimal pressure, slow passes, an extra-soft Polish \u0026amp; Sealing Foam Pad. That spreads the product ultra-fine and maxes out the gloss. For hobby users the step only pays off on dark paint or right after a polish — for everyday care the hand-applied cross pattern is enough.\u003c\/p\u003e\n\n\u003cp\u003eImportant: never use it below 10 degrees, never on hot paint in direct sun. Both extremes wreck the polymer chains. In the cold the carriers turn thick and flash off unevenly; in the heat the product dries before you can buff it. Sweet spot: 18 to 22 degrees, shade or indoors, still air with no dust flying around.\u003c\/p\u003e\n\n\u003ch3\u003eHonest durability. Weak in the spray zones.\u003c\/h3\u003e\n\n\u003cp\u003eThe Pfs gives excellent looks and feel, but it's no all-year sealant in the durability-test sense. On the bonnet and roof the water beading holds several weeks with normal use. On the rear, lower door flanks and sills the polymer layer visibly breaks down after around 500 kilometres of winter driving, from road salt and mechanical spray. A German detailing channel showed exactly that in a documented 14-day durability test.\u003c\/p\u003e\n\n\u003cp\u003eWhat it does well: aggressive bug removers and alkaline pre-washes only cost it 10 to 15 percent of its hydrophobia. The chemical resistance is surprisingly high for a pure polymer sealant. What it can't do: treat unprotected plastics (polypropylene goes white), seal unpainted rubber, or touch glass without a smearing risk. For glass you need a separate glass sealant — the polymers in the Pfs would streak across your line of sight, and you'd only get them off again with polishing compound.\u003c\/p\u003e\n\n\u003cp\u003eA second honest limit: the Pfs is no beading miracle in the maximum-droplet sense. If you want dramatically high water beads like on a fresh ceramic coating, here you'll see softer roll-off water — it protects just as well, it's just more low-key to look at. The product is tuned for slickness and deep gloss, not the show effect in a water test.\u003c\/p\u003e\n\n\u003cp\u003eIf you want an all-year protective coating effect, a real \u003ca href=\"\/en\/collections\/keramikversiegelung\"\u003eceramic coating\u003c\/a\u003e is the right call. It has far longer durability and higher mechanical resistance than any polymer spray sealant — but you're swapping a 30-minute spray job for a multi-hour application with a curing tent or garage. If instead you want a care topping that delivers deep gloss and slickness and can be machined on, the PerfectFinish Sealant is the product for you.\u003c\/p\u003e\n\n\u003cp\u003eIf you know the predecessor Spray Sealant \"S0.02\": the Pfs is the denser, slightly more demanding, but more durable evolution with a reworked polymer structure. With it Koch-Chemie deliberately tackled the main criticism of the S0.02 — the poor durability. In return the buffing is a bit more work, because the consistency is thicker.\u003c\/p\u003e\n\n\u003ch3\u003ePfs for hobby detailers and pro valeters\u003c\/h3\u003e\n\n\u003cp\u003eThe target group is ambitious hobby detailers who want a clean finish after polishing, and pro valeters who need one last slickness highlight after the coating. For pure car-wash drivers with no prep, the Pfs is too demanding. The 24-hour cure doesn't fit the quick programme.\u003c\/p\u003e\n\n\u003cp\u003eCoverage as an anchor: a 500 ml bottle covers about 20 to 25 car applications (mid-size, roughly 20 ml per car in a cross pattern over the cloth). The 5-litre pro container pays off from around 80 applications per season or in a valeting business. If-then, translated: 500 ml for one or two of your own cars a year, 5 litres once you're regularly sealing customer cars.\u003c\/p\u003e\n\n\u003cp\u003eIn the trends data, searches for \"spray sealant\" climb noticeably from April. The start of the season is the natural point for the yearly protective layer after the winter wear — and that same window is, in our experience, also the supply-bottleneck month, because a lot of valeters reorder at the same time.\u003c\/p\u003e\n\n\u003cp\u003eIn the workflow the Pfs pairs well with the \u003ca href=\"\/en\/products\/koch-chemie-quick-shine-qs-quick-detailer\"\u003eQuick \u0026amp; Shine \"Qs\"\u003c\/a\u003e. Quick detailer as a refresh between washes, Pfs as the base sealant renewed every 4 to 6 weeks. For the regular wash stick to pH-neutral shampoo so the polymer layer survives. Alkaline pre-washes are fine, but not every week.\u003c\/p\u003e\n\n\u003cp\u003eThe trick no manufacturer marketing leads with: if you've just laid down an expensive ceramic coating like the \u003ca href=\"\/en\/products\/koch-chemie-ceramic-allround-c0-02-keramikversiegelung\"\u003eCeramic Allround \"C0.02\"\u003c\/a\u003e, put the Pfs on top as a \u003cem\u003esacrificial layer\u003c\/em\u003e for the first few weeks. Fresh ceramic is prone to water spots during the curing phase, until the quartz network is fully hardened.\u003c\/p\u003e\n\n\u003cp\u003eThe Pfs polymers stop limescale from burning into the still-open coating. The spray sealant washes off after 4 to 6 weeks, the ceramic is fully cured by then, and the expensive coating underneath stayed clean. What we see day-to-day: in the detailing summer that's the most cost-effective protection stack you can run over a fresh ceramic coating.\u003c\/p\u003e\n","brand":"Koch-Chemie","offers":[{"title":"500ml","offer_id":57637119361359,"sku":"D1-KCX-685500","price":20.49,"currency_code":"EUR","in_stock":true},{"title":"5 liters","offer_id":57637057429839,"sku":"D1-KCX-685005","price":96.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-perfectfinish-sealant-pfs_f456fbe8-8b7c-4519-9875-b4af2974d234.png?v=1778703577"},{"product_id":"koch-chemie-ultra-foam-uf-snow-foam-stark-schaeumender-schaum-sb-waesche","title":"Ultra Foam \"Uf\" Snow Foam \/ High-foaming foam for the self-service wash","description":"\u003ch2 id=\"speakable-headline\"\u003eSnow Foam at pH 8.5 as the sweet-spot between gentleness and cleaning power\u003c\/h2\u003e\n\n\u003cblockquote id=\"speakable-summary\"\u003e\n  \u003cp\u003e\u003cem\u003eWhat is the Koch-Chemie Ultra Foam?

The diagnosis is nearly always the same: pH 9.5 cleans reliably, but breaks down polymer sealants over the weeks. Moving to pH 8.5 cuts the alkaline load by a factor of 10 and cleans almost identically in daily work. If you run decon washes before machine polishing, stick with Active Foam — if you maintain sealants, Ultra Foam is your pick.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eMixing Ultra Foam: cold bodywork, a thin film, five minutes\u003c\/h3\u003e\n\n\u003cp\u003eSpray Ultra Foam neat onto the paint and you risk caustic stains on anodised trim — in the foam lance, pull it down to a maximum of one percent working concentration and never work it undiluted.\u003c\/p\u003e\n\n\u003cp\u003eThat concentration is also the threshold at which the mildly alkaline cleaning action visibly kicks in. In the consumption channel of gantry wash systems, dosing typically sits at 3 to 8 ml per car. In the hand wash, dilutions up to 1:300 are plenty for a straight maintenance wash. In practice that means: a 1L bottle covers around 200 car pre-washes in the hand wash, the 5L drum roughly 1,000 applications.\u003c\/p\u003e\n\n\u003cp\u003eThe bodywork has to be cold and in the shade. Above 25 degrees of air temperature or in direct sun, the carrier water dries off faster than the mild alkali can work — the local concentration climbs, and you get water spots on the paint or milky haze on anodised aluminium trim. From what we see day-to-day: always check paint temperature with the flat of your hand; if the paint feels warm, hit it with a flush of water first until it's below skin temperature.\u003c\/p\u003e\n\n\u003cp\u003eApply in cross passes from the bottom up so run-off marks don't dry on. Five minutes dwell at most, then rinse it off completely with the pressure washer.

In unheated self-service bays the viscosity loses its flow and the dosing pump draws unevenly. The pro fix: pre-dilute the concentrate in the supply tank with warm water to 1:5 to 1:10 before it hits the venturi valve of the lance.

Applied correctly it leaves neither streaks nor water spots — provided you keep to the five-minute rule and the bodywork sits in the shade.\u003c\/p\u003e\n\n\u003cp\u003eOn sealants the real strength of pH 8.5 shows: modern ceramic coatings made of cross-linked silicon oxides — the covalent Si-O-Si matrix, a three-dimensional glass network on the paint — are unfazed by the mildly alkaline surfactant solution, because those bonds are orders of magnitude more chemically stable than the ester film of a wax. What that means for you: your coating's lifespan stays intact. Polymer sealants also last noticeably longer than under pH 9.5 — that factor of 10 in alkaline concentration translates directly into measurably longer protection-layer life.\u003c\/p\u003e\n\n\u003cp\u003eThe honest limitation: thinly applied carnauba waxes can still be undermined under weekly high concentration (1:10 instead of 1:100). Carnauba is a plant-based ester wax that gets broken down bit by bit by repeated contact with alkali. If you maintain a hand wax as a value-protecting layer, you don't run Ultra Foam at full strength as a weekly maintenance foam — for that niche the pH-neutral \u003ca href=\"\/en\/products\/koch-chemie-gentle-snow-foam-gsf-reinigungsschaum\"\u003eGentle Snow Foam \"Gsf\"\u003c\/a\u003e stays the better call, same maker, different use case.\u003c\/p\u003e\n\n\u003cp\u003eOn glass and unpainted polypropylene the product is uncritical as long as it doesn't dry on. On glass, baked-on alkali leaves a mineral haze that only an acidic glass cleaner will shift again.
