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-allround-surface-cleaner-asc-allzweckreiniger","title":"Allround Surface Cleaner \"Asc\" All-Purpose Cleaner","description":"\u003ch2\u003eReady-to-use and streak-free through the cabin with the Koch-Chemie Allround Surface Cleaner\u003c\/h2\u003e\n\n\u003cblockquote\u003e\n  \u003cp\u003e\u003cem\u003eWhat is the Koch-Chemie Allround Surface Cleaner? A ready-to-use, pH-neutral surface cleaner for plastic, displays, leather, glass and textile inside the cabin. Streak-free straight from the bottle, no diluting.

You apply it undiluted straight from the spray bottle. No mixing, no dilution chart, no measuring cup in a bucket.\u003c\/p\u003e\n\n\u003cp\u003eThat ready-to-use approach is exactly what sets the ASC apart from the alkaline Green Star out of the same house: there a concentrate for heavy shop grime, here a mild, fast helper for everyday interior care.

The mist from the spray bottle works its way into display edges, button gaps and speaker grilles, where it settles as a fine film you won't get back out later. Instead, lay down 2–3 squirts on the folded face of your microfibre cloth and work from there onto the surface. Only on big, closed panels like door cards or the headliner do you spray straight onto the part — there the mist doesn't matter.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eSpray, wait 30 seconds, microfibre after\u003c\/h3\u003e\n\u003cp\u003eYou spray the Koch-Chemie Allround Surface Cleaner undiluted onto the surface from about 10–15 cm, let it dwell for 15–30 seconds and wipe down with a clean microfibre cloth. That's all the prep it takes.\u003c\/p\u003e\n\n\u003cp\u003eOn bigger panels like the dashboard, door cards or headliner, three to five squirts per part is plenty. Give the cleaner a moment to break down skin oils, fingerprints and the dust-binding layer, then wipe down evenly with the dry side of your cloth. For vents, buttons and trim strips you spray onto the cloth first and work from there into the edges.\u003c\/p\u003e\n\n\u003cp\u003eTreat the headliner with extra care: only dampen the cloth, never spray the part directly. The headliner fabric mustn't get soaked, or the adhesive underneath lets go. With the ASC you work in broad, long passes so no dry edges form between the damp and the untreated areas.\u003c\/p\u003e\n\n\u003cp\u003eA common mistake is too much product and too long a dwell time. When the ASC flashes off, fine streaks stay behind that you then have to re-wet and wipe away — an avoidable extra round. So work panel by panel rather than across the whole surface, and keep the dwell time under a minute.\u003c\/p\u003e\n\n\u003cp\u003eWith a cleaning gun like the Tornador or Cyclone you can also work the ASC into textiles, seat seams and door pockets, where the cloth alone won't reach. The pH-neutral formula is built for it: it lifts the dirt into foam and picks back up with little residue. With the gun method, follow up afterwards with compressed air or a thirsty cloth so no moisture stays trapped in the part.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/asc_2_anwendung.jpg?v=1775896038\" alt=\"ASC sprayed onto a microfibre cloth in front of a car interior\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eStrengths and limits of the ASC day-to-day\u003c\/h3\u003e\n\u003cp\u003eThe ASC is pH-neutral and ready-to-use.

That's what the product was made for.\u003c\/p\u003e\n\n\u003cp\u003eOn coated leather, piano black and gloss trim the neutral pH is an extra safety net that takes away the material guesswork that always rides along with alkaline interior cleaners. You don't have to think before every use about whether the product suits the material — on normal plastic, glass and leather surfaces in the car the ASC is a safe call.\u003c\/p\u003e\n\n\u003cp\u003eWhat the ASC won't do: it won't shift old nicotine films, an oily workshop grip on the door frame or coffee stains baked into the fabric. Badly yellowed plastics on the sill or a dried cola splash in the cup holder need more muscle too. If your cabin gets cared for regularly, the Allround Surface Cleaner is your product.\u003c\/p\u003e\n\n\u003cp\u003eWhen you're prepping a lease return or getting a used car ready to sell, grab the alkaline \u003ca href=\"https:\/\/detailing1.de\/products\/koch-chemie-green-star-gs-universalreiniger\"\u003eheavy-duty cleaner\u003c\/a\u003e and then use the ASC afterwards on the finer surfaces like displays, leather and gloss trim.

The pH of 12.5 in the concentrate saponifies fats and oils through alkaline hydrolysis — something pH-neutral cleaners simply can't do chemically. Dilute it 1:10 and you sit around pH 11, which is plenty for most interior surfaces in the car. Koch-Chemie has it under an official Daimler approval, which is why detail shops and workshops keep it on the shelf as a default.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-mehrzweckreiniger-mzr-universalreiniger_hero.png?v=1776196784\" alt=\"Koch-Chemie Mzr 1L bottle next to the open door of a black Mercedes-AMG GT in the warehouse bay\" width=\"900\" loading=\"lazy\"\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDilute from 1:5 to 1:50 — one concentrate for any kind of dirt.\u003c\/strong\u003e For heavy jobs like motor oil or nicotine films you work at 1:5.

Always dilute in the bottle first and start at 1:10. If that does the job, dial down to 1:20 next time. The most common mistake we see day-to-day: people run the dilution too strong and end up with white patches on dark plastics because the alkalinity has attacked the surface. Two passes at 1:10 give you a better, more even result than one pass at 1:5.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003e1:10 on the headliner. 1:50 on the door handle.\u003c\/h3\u003e\n\u003cp\u003eKoch-Chemie Mzr works as a concentrate that you dilute fresh for every job. That sets it apart from ready-mixed \u003cstrong\u003einterior all-purpose cleaners\u003c\/strong\u003e like the \u003ca href=\"\/en\/products\/koch-chemie-multi-interior-cleaner-innenraumreiniger-750ml\"\u003eKoch-Chemie MultiInteriorCleaner\u003c\/a\u003e, which come at a fixed strength you can't change.\u003c\/p\u003e\n\n\u003cp\u003eFor a nicotine-stained headliner or greyed fabric seats you work at 1:5 to 1:10. Spray it on evenly, let it dwell for 1–3 minutes, then work it in with a soft detailing brush in circles. The Mzr lifts the dirt chemically, the brush pulls it out of the fibres. After that you extract the dissolved soil with a clean microfibre or a wet vac. On headliners the wet vac is non-negotiable — too much standing moisture softens the textile glue and the headliner starts to sag.\u003c\/p\u003e\n\n\u003cp\u003eFor everyday interior cleaning — dash, centre console, door cards — 1:20 to 1:50 is enough. At that strength the Mzr is gentle enough for most hard plastics. The surface comes out clean and there's no greasy film left behind.\u003c\/p\u003e\n\n\u003cp\u003eRight after that you can lay down a plastic dressing — the Mzr leaves no residue that would block adhesion. That's what makes it the go-to prep step before any dressing. Still: on soft-touch steering wheels and rubberised grips even the weakest dilution is a gamble. Grab a pH-neutral cleaner for those.\u003c\/p\u003e\n\n\u003cp\u003eOutside the cabin the Mzr earns its name too: workshop floors with oil stains, grimy industrial machines, weathered motorhome trim. For outdoor use go 1:5 to 1:10 and let it dwell 3–5 minutes. Hit it with a pressure washer or a brush, then rinse off.\u003c\/p\u003e\n\n\u003cp\u003eOne detail Koch-Chemie doesn't flag on the product page: the Mzr leaves a subtle, clean scent on the surfaces it cleans. Not an artificial air freshener — just noticeably less chemical than comparable industrial cleaners. In a smoker's car it won't mask the nicotine smell, but after the clean the cabin smells neutral instead of like cleaning chemicals. Sounds like a side-effect, but in the bay it matters when you're prepping cars for resale or hand-back.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-mehrzweckreiniger-mzr-universalreiniger_anwendung.png?v=1776198150\" alt=\"Headliner cleaning with diluted Koch-Chemie Mzr from an iK Multi TR 1 spray bottle in a Mercedes-AMG GT\" width=\"900\" loading=\"lazy\"\u003e\n\n\u003ch3\u003eKoch-Chemie Mzr lifts nicotine films. Leather, it attacks.\u003c\/h3\u003e\n\u003cp\u003eOrganic dirt is the home turf of Koch-Chemie Mzr: greasy fingerprints, nicotine films, soot, ink stains and that typical grey ingrained look on light upholstery after two years of daily use. The alkaline formula handles those in one pass.\u003c\/p\u003e\n\n\u003cp\u003eThe colour shift from clean to dirty is instant on the Mzr — the microfibre after a wipe shows exactly what came out of the surface. Most dramatic on greyed light fabric seats: the first pass often pulls two shades of difference out. That's not a marketing line — it's the chemical effect of alkaline saponification breaking down the deep-set fat soiling that a neutral cleaner can't reach.\u003c\/p\u003e\n\n\u003cp\u003eKoch-Chemie positions the Mzr as an \u003cstrong\u003einterior all-purpose cleaner\u003c\/strong\u003e for cars, industry and building maintenance. The pack sizes tell you the same story: the 1-litre bottle sits next to 11 kg, 21 kg and 225 kg drums. This is a workshop cleaner that also works in the car interior. That origin is where the strength comes from — the Mzr is formulated for industrial grime, and that power follows it into the cabin.\u003c\/p\u003e\n\n\u003cp\u003eWhere the Mzr isn't the right tool: on genuine and synthetic leather with open-pore structure the alkalinity can dry out the surface and leave discolouration. Leather wants a pH-adjusted leather cleaner. On soft-touch plastics and rubberised surfaces like steering wheels or shift knobs it leaves dull patches. On painted or wrapped panels an alkaline cleaner has no business at all — even diluted 1:50, the pH still sits above 9. When you need an \u003ca href=\"\/en\/collections\/universalreiniger\"\u003eall-purpose cleaner\u003c\/a\u003e with no risk for sensitive materials, the Koch-Chemie ASC is the safer pick — ready-mixed, pH-neutral, surface-agnostic.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-mehrzweckreiniger-mzr-universalreiniger_ergebnis.png?v=1776196797\" alt=\"Headliner before and after cleaning with Koch-Chemie Mzr – nicotine grey on the left, deep black alcantara on the right\" width=\"900\" loading=\"lazy\"\u003e\n\n\u003ch3\u003eOne drum of Koch-Chemie Mzr. 200 litres of working solution.\u003c\/h3\u003e\n\u003cp\u003eThe Koch-Chemie Mzr pays back on yield. One litre of concentrate at 1:20 dilution gives you 21 litres of ready-to-use cleaner — enough for 15–20 full interior cleans. At €7.67 a litre that works out to under €0.50 per car.

If you only clean the interior occasionally and don't want to mess with dilution, grab the MultiInteriorCleaner ready to use. If you want flexibility — stronger for a smoker's cabin, weaker for the weekly wipe-down — the Mzr is the cheaper bet.\u003c\/p\u003e\n\n\u003cp\u003eFor day-in, day-out workshop use we run a Koch-Chemie tap on the 11-kg drum: dose the concentrate into the bottle, top up with water, done. The 1-litre bottle is the one to keep for mobile work and the detailing kit. Store both frost-free between 5 and 30 °C; sealed concentrate keeps for 24 months. Use any diluted mix within four weeks.\u003c\/p\u003e\n\n\u003cp\u003eOne safety note to finish: the Mzr is classified as corrosive (H314) and carries the signal word \"Danger\". In the concentrate, always wear gloves and safety glasses. At normal working dilutions of 1:10 to 1:20 the risk drops a lot, but you still want to avoid prolonged skin contact. The safety data sheet is on the product page for download.\u003c\/p\u003e\n\n\u003cp\u003eBottom line: the Koch-Chemie Mzr isn't an everyday quick-wipe cleaner.
