Soak the pad. Work it to translucent.\u003c\/h3\u003e\n\u003cp\u003eThe Heavy Cut H9.02 only goes on cold, dry, contamination-free paint. Leftover contamination acts like grit and cuts fresh scratches.\u003c\/p\u003e\n\n\u003cp\u003eBefore every polishing round, the paint needs degreasing — best with an IPA cleaner from the prep range, to kill off any wax residue first. For machine choice, the maker sets a clear order: a rotary at medium speed for maximum cut.\u003c\/p\u003e\n\n\u003cp\u003eThe 2024 generation of the Heavy Cut pads now also lets you run them on dual-action polishers (DA polishers) — gloss stays comparable, the cutting time per panel goes up by about 20 percent. On the fresh pad you lay down an even film when you prime, spread it with finger pressure while the machine is off, then start at speed 1 to 2.\u003c\/p\u003e\n\n\u003cp\u003eWorking a crosshatch pattern with moderate pressure, you take a panel of 40 by 40 centimetres until the compound goes translucent. That is the point where the abrasives have fully broken down and the aluminium oxide has hit its finest grade.\u003c\/p\u003e\n\n\u003cp\u003eBefore that point the grit still cuts too hard and leaves a rough microsurface; past that point the pad runs dry and throws holograms. Two to three section passes per panel is the standard — on heavier defects, shrink the panel rather than stretch the working time.\u003c\/p\u003e\n\n\u003cp\u003eYou wipe the residue off with a clean, edgeless microfibre cloth — don't rub, wipe. Between panels, check the pad for saturation: if it is caked and shiny, loosen it up with a pad-cleaning brush; if it is smeared, swap it instead of fighting on.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-heavy-cut-h9-02-grobe-schleifpolitur_anwendung.jpg?v=1776554761\" alt=\"Detailing1 applying Koch-Chemie Heavy Cut H9.02 with a rotary on clear coat\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eCut rating 9.0 clears P1200. Down to primer it won't.\u003c\/h3\u003e\n\u003cp\u003eThe Koch-Chemie Heavy Cut H9.02 is a correction compound, not a repair. Anything that sits within the thickness of the clear coat — swirls from automatic car washes, buffer trails, sanding marks after wet-sanding down to P1200, water-spot etching, light bird-dropping etching, UV dulling — comes back in one to three passes. Anything that already reaches into the colour coat or primer won't be fixed by any polish on earth.\u003c\/p\u003e\n\n\u003cp\u003eA paint thickness gauge is a must for serious work at cut rating 9. Modern OEM clear coats run between 40 and 60 microns, and a single H9.02 pass takes off 1 to 3 microns depending on pad and pressure. Work with no gauge and correct three times, and on jet-black clear coat you'll be down to the colour coat faster than you'd think — and then neither a finishing polish nor a sealant saves you, only a respray.\u003c\/p\u003e\n\n\u003cp\u003eThe honest limits: bitumen, tar and silicone stains don't react chemically with the aluminium oxide — for those you need a tar remover before you polish. Very soft Japanese clear coats (Toyota white, a few Mazda reds) can tip into the hologram phase fast with the lambswool pad, so here you're better off starting straight with the Foam Pad Red.\u003c\/p\u003e\n\n\u003cp\u003eFor fine correction of medium scratches the H9.02 is overkill — that's where the \u003ca href=\"\/en\/products\/koch-chemie-fine-cut-f601-schleifpolitur-fein\"\u003eFine Cut F6.01\u003c\/a\u003e is the right tool.

For the occasional polisher it's overkill.\u003c\/p\u003e\n\n\u003cp\u003eIt's aimed at keen home detailers with a rotary or DA polisher, semi-pro reconditioners with a regular fleet workload, and shops prepping used cars for resale. If you refresh your new car once a year, you're a lot better off with a finer polish like the F6.01 or an all-rounder.\u003c\/p\u003e\n\n\u003cp\u003eOn cost, the 250 ml bottle is already the standard size for home use: at 2 to 3 millilitres per panel it lasts for around 100 to 125 panels, or roughly three to four full corrections — that works out to a material cost of about 14 to 17 cents per panel, priming the pad included. The 1-litre bottle pays off from the tenth correction job a year, and the 5-litre canister is the bulk size for outfits running flat out.\u003c\/p\u003e\n\n\u003cp\u003eIn day-to-day Detailing1 work the H9.02 never stands alone — it's step 1 in a two- to three-stage polishing system. The typical Koch-Chemie workflow: H9.02 on the Heavy Cut Pad Red for the coarse correction, Fine Cut F6.01 on the Fine Cut Foam Pad Yellow to even out the sanding structure, Micro Cut M3.02 to clear the holograms. Skip step 3 and you accept visible micro-sanding marks on dark paint. Over 87 percent of our H9.02 buyers add the F6.01 to the same basket — exactly for this reason.\u003c\/p\u003e\n\n\u003cp\u003eBut the biggest lever for a clean result is neither the polish nor the pad — it's the state of the paint before the first drop. Clean prep — clay bar, IPA wipedown, taping off the trim — saves a full polishing pass on average.\u003c\/p\u003e\n\n\u003cp\u003eThe best H9.02 tip from our bench, though, only comes at the end: after polishing, wipe the paint down with IPA again before you seal. The leftover oils from the pad are otherwise enough to cut the lifespan of a ceramic coating by 30 to 40 percent — and you only notice three months later. Keep pads damp after the session in a bucket of warm water and pad cleaner, don't let them dry out — that halves their service life.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-heavy-cut-h9-02-grobe-schleifpolitur_lineup.jpg?v=1776554776\" alt=\"Koch-Chemie Heavy Cut H9.02 250ml 1000ml 5 litre line-up Detailing1\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n","brand":"Koch-Chemie","offers":[{"title":"1000 ml \/ 1 liter","offer_id":48495549710671,"sku":"D1-KCX-458001","price":61.49,"currency_code":"EUR","in_stock":true},{"title":"250ml","offer_id":48495549677903,"sku":"D1-KCX-458250","price":18.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-heavy-cut-h9-02-grobe-schleifpolitur.jpg?v=1710775571"},{"product_id":"koch-chemie-heavy-quick-cut-b9-01-starke-schleifpolitur","title":"Heavy Quick Cut \"B9.01\" Heavy Cutting Compound","description":"\u003ch2\u003eKnock out deep scratches and heavy oxidation in one step — with the Koch-Chemie Heavy Quick Cut \"B9.01\" Heavy Cutting Compound\u003c\/h2\u003e\n\u003cblockquote\u003e\u003cem\u003eThe Koch-Chemie Heavy Quick Cut \"B9.01\" is a powerful cutting compound with cut grade 9.0 for machine correction of deep scratches, heavy oxidation and coarse sanding marks from P1500 grit upward — silicone-oil-free, suitable for all paint types and built to be the first stage in Koch-Chemie's multi-step polishing process.\u003c\/em\u003e\u003c\/blockquote\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCut grade 9.0 — the most aggressive cut in the polishing range\u003c\/strong\u003e — for deep scratches, heavy oxidation and coarse sanding marks from P1500.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSilicone-oil-free, plays nice with every coating\u003c\/strong\u003e — no silicone fillers that mask paint defects instead of correcting them.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow dust and sling\u003c\/strong\u003e — built for clean work with rotary and dual-action machines, without throwing product everywhere.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat do you actually need a heavy cut compound for — and when is it the right call?\u003c\/h3\u003e\n\u003cp\u003eIn the Koch-Chemie polishing system, the \u003cstrong\u003eHeavy Quick Cut B9.01\u003c\/strong\u003e is the heaviest hitter in the lineup. With a cut grade of 9.0, it's built for paint that finer compounds like the Fine Cut F6.01 or the Lack-Polish range simply won't cut deep enough on. Where it earns its keep: badly oxidised paint on older cars, deep holograms after years of automatic car washes, coarse sanding marks after wet-sanding (P1500 grit and up), scratches that go past the clear coat, or the opening stage of a full paint correction. The difference from a basic polishing paste comes down to abrasive size and hardness — the B9.01 actually removes material instead of just filling defects. That's why you always follow it up: after the B9.01 comes a refining step with the \u003ca href=\"https:\/\/detailing1.de\/products\/koch-chemie-fine-cut-f601-schleifpolitur-fein\"\u003eFine Cut F6.01\u003c\/a\u003e or the \u003ca href=\"https:\/\/detailing1.de\/products\/koch-chemie-micro-cut-finish-p3-01-micro-schleifpolitur-carnaubawachs\"\u003eMicro Cut \u0026amp; Finish P3.01\u003c\/a\u003e, to polish out the micro-scratches the heavy cut leaves behind.\u003c\/p\u003e\n\u003ch3\u003eMachine choice and pad pairing for maximum cut\u003c\/h3\u003e\n\u003cp\u003eThe B9.01 hits hardest on a \u003cstrong\u003erotary polisher\u003c\/strong\u003e with a heavy cut pad (firm foam or wool). Rotaries build more heat and friction through their combined spin-and-travel motion — which fires up the B9.01's abrasives more effectively. You can run the B9.01 on a dual-action with the right heavy cut pad too, you'll just get less bite than off a rotary. Five pea-sized drops on the pad, spread them at low speed, then work with medium pressure and medium speed in crosshatch passes. Don't let the compound flash off and dry on the panel.\u003c\/p\u003e\n\u003ch3\u003eSilicone-oil-free — why that matters for proper paint correction\u003c\/h3\u003e\n\u003cp\u003eA lot of cheaper cutting compounds lean on silicone oils as fillers: they visually hide micro-scratches without actually removing them — it looks fresh, but the defects are still there and resurface a few weeks down the line. Silicone oils also mess with the bond of sealants and ceramic coatings. The Koch-Chemie B9.01 is formulated silicone-oil-free — what you see after working it is the real result, not a masked impression. Even so, degrease with the \u003ca href=\"https:\/\/detailing1.de\/products\/koch-chemie-panel-preparation-spray-entfetter-kontrollspray\"\u003ePanel Preparation Spray PPS\u003c\/a\u003e before you seal after the B9.01 — even silicone-free compounds leave carrier residue on the paint.\u003c\/p\u003e\n\u003cblockquote class=\"praxistipp\"\u003e\n\u003cp\u003e\u003cstrong\u003eDetailing1's tip from the shop:\u003c\/strong\u003e Always start the B9.01 on a small test patch — on thin or sensitive clear coats (a lot of modern cars from 2015 on) cut grade 9.0 can burn through if you lean on it too hard or pick the wrong machine. Start at low machine speed, check the result under light, then build up in measured steps.

If you want to correct light to medium scratches in one step and pull a high-gloss finish at the same time, grab the purple P2.03.

With a cut rating of 2.0 and a gloss rating of 9.3, the P2.03 picks up exactly where classic finishing products run out of steam, without crossing over into the territory of coarse cutting compounds.

What that means in practice is easy to picture with the cut rating of 2.0. That figure sits well below cutting compounds like the Koch-Chemie Heavy Cut H9.02 (cut rating 9.0), but noticeably above a pure finishing polish with no bite at all. The abrasives in the P2.03 are fine enough to mechanically level out hazing, holograms and fine scratches down to a certain depth — yet they remove so little material that delicate paints, clear coats and even scratch-resistant systems can be worked without a second thought. What surprises a lot of people day-to-day: the P2.03 doesn't dry out while you work it, and it spreads happily even at moderate temperatures without the polish flashing off on the surface. The gloss rating of 9.3 is one of the highest finish values in the Koch-Chemie line-up — for a sense of what that means: the Micro Cut M2.02 also hits high gloss, but it's geared purely toward hologram and swirl correction with no protective component. The P2.03 adds the bonus of built-in protection, which makes it the more efficient pick in a lot of detailing workflows. Important for dark paint: on black or deeply pigmented clears, holograms and hazing show up the most — and this is exactly where the P2.03 plays to its strengths, because the high gloss rating brings out the depth and colour saturation of these paints beautifully.\u003c\/p\u003e\n\n\u003ch3\u003eUsing the Lack-Polish violett the right way — workflow, pads and machines\u003c\/h3\u003e\n\u003cp\u003eBefore the P2.03 touches the surface, give the car a thorough wash and — depending on the state of the paint — decontaminate it with a clay bar. Fallout, tar residue and brake dust left on the paint would get dragged in during polishing and could cut in deep scratches. Give the P2.03 a good shake before you use it. Never work the paint in direct sun or on hot surfaces — that goes for the P2.03 and any polish, full stop. For the best cut, Koch-Chemie recommends a rotary at medium speed; the cleanest finish with no machine marks comes off a dual-action polisher. In the two-stage Koch-Chemie system the P2.03 is typically the final polishing step: step 1 handles the heavy correction (Heavy Cut H9.02 or Fine Cut F6.01), step 2 the abrasive gloss polish with the P2.03 or, alternatively, the Micro Cut M2.02. If you want to lay down a protective layer afterwards, you can apply the \u003ca href=\"https:\/\/detailing1.de\/products\/koch-chemie-ceramic-allround-c0-02-keramikversiegelung\"\u003eCeramic Allround C0.02 ceramic sealant\u003c\/a\u003e — the protective wax content of the P2.03 won't get in the way as long as you wipe the panel down with IPA first. Once you've worked it out, buff the polish residue to a high gloss with a soft Polish \u0026amp; Sealing Towel — don't lean on it, just finish it off.\u003c\/p\u003e\n\n\u003ch3\u003eResults and where the abrasive gloss polish P2.03 shines\u003c\/h3\u003e\n\u003cp\u003eThe P2.03 delivers its best results on lightly to moderately weathered paint — which is exactly the state most daily-driven cars are in. The typical jobs: a car that's spent years parked outside with a clear coat gone slightly matt from UV; a used car carrying holograms from car-wash visits; a brand-new car showing its first swirl marks after the first run through winter. In every one of those cases the P2.03 has enough correction depth to bring the surface back to a high gloss without needing an upstream heavy-cut step. The same goes for motorbikes, vans and motorhomes: wherever there's painted bodywork, the P2.03 can go to work — by machine or with a hand applicator for small areas and tight spots. For pro detailers the P2.03 is especially worth a look when no ceramic coating follows the job and the polish's wax film is enough to serve as short-term protection.\u003c\/p\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDetailing1's tip from the shop:\u003c\/strong\u003e The pad decides the character of the P2.03.

Only ever drop five pea-sized blobs on the pad — the P2.03 goes a long way, and too much polish makes it harder to work out.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003ch3\u003eP2.03 compared: when to reach for Micro Cut M2.02 or Fine Cut F6.01 instead?\u003c\/h3\u003e\n\u003cp\u003eThe Koch-Chemie line-up has three polishes that look like they do similar jobs at first glance, but in the detail they have clearly different strengths. The \u003ca href=\"https:\/\/detailing1.de\/products\/koch-chemie-micro-cut-m2-02-hochglanz-antihologramm-politur\"\u003eMicro Cut M2.02\u003c\/a\u003e is the pure anti-hologram and high-gloss polish with no protective content — the right call when a ceramic or polymer coating follows the polish, because no wax residue messes with the bonding surface. If you want to seal straight after polishing, you take the M2.02 and wipe the panel down with IPA. The P2.03, on the other hand, is the better shout when the paint needs to stay looking good for a few weeks or months with no sealant — the built-in wax content protects and shines at the same time. The Fine Cut F6.01 sits a step up in abrasiveness: cut rating 6.0 for medium scratches and oxidation. If you've got deeper defects the P2.03 can't fully correct on its own, you start with the F6.01 and finish with the P2.03 — that's the classic two-stage Koch-Chemie system. If you've already knocked out the correction work before the P2.03 with a hard \u003ca href=\"https:\/\/detailing1.de\/products\/koch-chemie-polierpad-heavy-cut-foam-pad-rot-2024\"\u003eHeavy Cut Foam Pad Rot\u003c\/a\u003e and a stronger polish, the P2.03 gets you to that perfect finish. The competition — say Menzerna Super Finish SF 3800 or Rupes UNO Protect — also offers gloss polishes with a protective component, though often without the same flexibility from pad choice. Koch-Chemie's colour system makes the pad pairing especially practical: violet pad = P2.03, no risk of mixing them up under time pressure.\u003c\/p\u003e\n\n\u003ch3\u003eWho is the Koch-Chemie Lack-Polish violett P2.03 the right choice for?\u003c\/h3\u003e\n\u003cp\u003eThe P2.03 is the perfect pick for ambitious hobby detailers and professional reconditioners after a product that brings correction and high gloss together in a single bottle. If you're working a car with light to moderate weathering and don't necessarily want to lay down a sealant afterwards, the P2.03 is the most efficient finishing step in your workflow.

The \u003cstrong\u003eKoch-Chemie Cosmo-Clean \"Cc\"\u003c\/strong\u003e was built for exactly this commercial-grade load. The mildly alkaline formulation cuts through grease, oil and dirt residue without harsh solvents — NTA-free and with no halogenated compounds. That's not just an eco win: solvent-free cleaners play far better with light-liquid separators, which is often a hard requirement in commercial workshops and industrial halls. The chosen mix of wash-active agents and phosphates still delivers outstanding cleaning power even at high dilution.\u003c\/p\u003e\n\n\u003ch3\u003eDilution ratios and where you'll use them day-to-day\u003c\/h3\u003e\n\u003cp\u003eThe Cosmo-Clean's strength is just how far you can dilute it: on lightly soiled office and admin floors you mix the concentrate 1:60 to 1:300 — a sparing dose that makes the 11 kg canister go even further. For heavily soiled workshop and industrial floors, Koch-Chemie recommends a 1:40 to 1:120 dilution for machine or manual cleaning. So you dial in the dose to match how dirty the floor is, no swapping products. Using it couldn't be simpler: lay the concentrate down on the surface, let it dwell depending on the dirt, then rinse off with a scrubber-drier, a steam jet or a pressure washer.\u003c\/p\u003e\n\n\u003ch3\u003eSafety aspects — what \"safety cleaner\" actually means\u003c\/h3\u003e\n\u003cp\u003eThe term \"safety floor cleaner\" isn't marketing fluff, it's a technical classification: the product is fast-separating to ÖNORM 5105 and therefore suited to wastewater systems with light-liquid separators. In a car workshop or industrial hall that's often a legal requirement — cleaners mustn't overload the oil separator with surfactant concentrates. The Cosmo-Clean meets those requirements. The slip-resistant effect is another safety factor: floors that are still wet are a real accident risk when you're working with other cleaners — the Cosmo-Clean cuts that risk right down thanks to its special formulation.\u003c\/p\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDetailing1's tip from the shop:\u003c\/strong\u003e For detailing shops, the Cosmo-Clean really shines for cleaning the floor after polishing work, once polishing dust has settled onto it. The low-foaming formula also makes it a great match for scrubber-driers — no foam overflow inside the machine. Mixing it up in a dosing sprayer makes it easier to lay down evenly across big areas.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003ch3\u003eCosmo-Clean vs. Green Star — when to reach for which?\u003c\/h3\u003e\n\u003cp\u003eAlongside the Cosmo-Clean, the Koch-Chemie range also offers the Green Star BMP as an all-purpose cleaner. The difference comes down to where you use them: the Cosmo-Clean is built specifically for floor cleaning — mildly alkaline, slip-resistant and gentle on floor sealants. The Green Star is a broader all-purpose cleaner — for vehicle surfaces, engines, wheels and floors, but without that specific slip-resistant property. If you only clean floors and have to meet safety requirements (ÖNORM, light-liquid separators), the Cosmo-Clean is the one to grab.\u003c\/p\u003e\n\n\u003ch3\u003eWho is the Koch-Chemie Cosmo-Clean the right pick for?\u003c\/h3\u003e\n\u003cp\u003eThe Cosmo-Clean is aimed at car workshops, dealerships, detailing businesses and industrial operations that regularly clean large floor areas and have to keep an eye on both cleaning power and legal wastewater requirements.

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.

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.

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 detail regularly, grab the 11-kg drum: at €77.75 you're at €7.07 per kilo and around 200 litres of working solution at 1:20.\u003c\/p\u003e\n\n\u003cp\u003eThe Mzr is built for detailers, workshops and serious hobby detailers who want a concentrate over ready-mixed bottles. 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 active blend — C10–C13 n-alkanes, isoalkanes and cycloalkanes with under 2 percent aromatics — chemically breaks apart the molecule chains in bitumen and tar. The residue runs off in streaks and you either steam it away with the pressure washer or wipe it off with a microfibre cloth.\u003c\/p\u003e\n\n\u003cp\u003eFree of halogenated hydrocarbons, so it's a lot kinder to materials than the old-school tar removers people kept in jerry cans back in the 90s. Available in 1 litre, 10 litre and 20 litre — plus a 2-pack and 3-pack when you need more. Alongside the alkane blend the formula carries a share of 2-butoxyethanol as a coupling agent, which improves how it wets a glass-smooth panel and keeps it working even at cooler ambient temperatures. For indoor use, run ventilation above three air changes an hour, and eye protection is a must for any overhead work.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChemical, not mechanical.\u003c\/strong\u003e You can't polish tar out — scrubbing drags the particles across the paint and leaves swirls behind.

That's the bit manufacturers and rivals rarely mention. If you do nothing after the tar comes off, you're left with unprotected paint that takes on fallout and water spots with no barrier. So always plan it in as the first step of a combo job: tar wash → normal wash with a pH-neutral shampoo → reseal with a \u003ca href=\"\/en\/products\/sonax-profiline-speedprotect-spruhversiegelung\"\u003espray sealant\u003c\/a\u003e or wax. For a spot job (the odd tar fleck on the sill) a quick detailer is enough as local protection. For a full exterior job including resealing, set aside about 45 minutes for a mid-size car.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eSpray it on neat. Short dwell. Steam it off.\u003c\/h3\u003e\n\n\u003cp\u003eThe application is kept deliberately simple. Lay Teerwäsche A on the dry, cold surface undiluted — either straight from the 1-litre bottle with the \u003ca href=\"\/en\/products\/koch-chemie-teerwaesche-a-tea-bitumen-teerentferner?variant=54013040492879\"\u003eCanyon spray head CHS-3AN\u003c\/a\u003e or from a sturdy solvent-safe spray bottle. A wet surface dilutes the solvent and cuts the cleaning power right down — when washing, tar wash first, then shampoo.\u003c\/p\u003e\n\n\u003cp\u003eDwell time runs from 30 seconds to 3 minutes — depending on how thick the tar layer is. You can see when it's working: the tar dissolves into brownish-black streaks and runs down vertical surfaces. As soon as that happens, rinse straight off with a strong jet of water or wipe it away with a clean microfibre cloth. A 1000 ml bottle covers roughly 4 to 6 full vehicle sides with moderate tar.\u003c\/p\u003e\n\n\u003cp\u003eOn bigger areas, don't let it dry — in direct sun or on hot paint above 25 °C the solvent flashes off too fast and leaves an oily film that only comes off at the next wash. For underbody or wheel-arch work on commercial vehicles, the 10 or 20 litre version is the right call.\u003c\/p\u003e\n\n\u003cp\u003eThere you apply it over a wide area with a pump sprayer and then steam it off with the pressure washer at around 120 bar. On stubborn, dried-on bitumen spots after a drive through roadworks, a second application does more than a longer dwell on the first pass — the solvent is saturated after about 3 minutes and stops working.\u003c\/p\u003e\n\n\u003ch3\u003eIt breaks down tar. And wax too.\u003c\/h3\u003e\n\n\u003cp\u003eTeerwäsche A attacks any organic coating sitting on the paint. That's how it works — and at the same time it's the one catch for anyone who reaches for it without a plan. Carnauba waxes, synthetic polymer-based sealants and most quick detailers dissolve away on contact with the hydrocarbon blend. That's no fault in the product either, it's chemistry: what breaks down bitumen breaks down wax too, because both are built on similar organic molecule structures.\u003c\/p\u003e\n\n\u003cp\u003eFor the real world that means two things. First: every tar wash is followed by a full paint wash with a pH-neutral shampoo to neutralise the solvent residue. Second: the treated spot needs a fresh layer of protection.\u003c\/p\u003e\n\n\u003cp\u003eIf you're only dealing with small flecks on the side sill, you can follow up with a spot wax or detailer. If you're cleaning whole panels or the underbody, build the reseal into the workflow as a fixed step. SiO₂-based ceramic coatings usually aren't fully wrecked after a tar-wash treatment, but they lose noticeable hydrophobicity — a topper or detailer brings them back up to level.\u003c\/p\u003e\n\n\u003cp\u003eWhat Teerwäsche A isn't suited to: unpainted soft plastics, rubber seals and EPDM profiles. The solvent swells rubber over longer contact and can dull plastics. It mainly hits window seals, door rubbers and black plastic trim on older vehicles.\u003c\/p\u003e\n\n\u003cp\u003eDon't spray it over those surfaces broadly — if overspray happens, rinse it off with water within 60 seconds. On fresh wraps and PPF (paint protection film), test first on a hidden spot. Plenty of PPF coatings handle short contact times under 30 seconds but react sensitively to longer exposure.\u003c\/p\u003e\n\n\u003ch3\u003eWhen Teerwäsche A fits — and when it doesn't\u003c\/h3\u003e\n\n\u003cp\u003eTeerwäsche A is the right call when you're removing genuine road tar, bitumen spray after driving through roadworks, asphalt residue on wheel arches or dried-on oil films in the underbody area. It's also built for the regular cleaning of car-wash brushes and shop floors — wherever it's not paint cosmetics that's needed but real chemical solving power. In the spring season after winter it's standard for underbody prep, once tar-salt mixes have piled up over months.\u003c\/p\u003e\n\n\u003cp\u003eFor insect residue, though, it's not the first choice. Insect proteins are organic but structured differently — enzymatic cleaners like the \u003ca href=\"\/en\/collections\/insektenentferner\"\u003einsect remover\u003c\/a\u003e work more precisely and more gently on paint there. If you've got both at once — tar on the sill, bugs on the front end — treat both areas separately with the product that fits each. Trying to solve everything with one all-rounder usually ends in more rework. Same goes for tree sap and adhesive residue: both dissolve with the tar wash, but a dedicated tree-sap remover works cleaner.\u003c\/p\u003e\n\n\u003cp\u003eAs for pack size, the 1-litre bottle suits the private user and the occasional detailer planning one go per vehicle. The 2-pack and 3-pack bring the price per litre down by roughly 5 to 15 percent — worth it if there are several vehicles in the household or you want the season's supply locked in.\u003c\/p\u003e\n\n\u003cp\u003eThe 10 and 20 litre drums are trade sizes for reconditioning, underbody cleaning or fleet work — here the outlay only pays off from regular weekly use. For precise single-spot application the 1-litre bottle with the Canyon spray head stays the most ergonomic solution. The spray head delivers a precise cone rather than a mist and doses right onto the problem spot without wetting more area than needed.\u003c\/p\u003e\n\n\u003cp\u003eStore Teerwäsche A frost-free at room temperature.

Above 30 degrees paint temperature the cleaner flashes off before the dwell time is up — leaving dull streaks that only come off with polish. Before you start, move the vehicle into the shade or rinse it down with cold water first. In full summer sun, reach for the milder Pre-Foam efficient instead, which is far more forgiving with its 1-minute maximum dwell time.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003e1:30 for insects. 1:300 for high pressure.\u003c\/h3\u003e\n\u003cp\u003eDilution depends on how dirty the vehicle is and how you apply it. 1:30 to 1:50 for the pre-wash, 1:3 to 1:10 for heavily soiled wheels, 1:300 for self-service high-pressure units.\u003c\/p\u003e\n\u003cp\u003eFor the touchless pre-wash with a foam lance you work at 1:30 to 1:50. One litre of concentrate at 1:50 gives you 51 litres of ready-to-use solution — enough for roughly 20 to 25 cars in standard exterior care.\u003c\/p\u003e\n\u003cp\u003eThe foam lance should run at 0.8 to 1.2 litres per minute flow so the foam consistency is right and the cleaner clings to vertical panels long enough to do its job. Apply the pre-cleaner from the bottom up onto the cold, pre-wetted vehicle — that way you avoid run marks on unevenly dried panels. After 5 minutes dwell time at most (VDA Class A), rinse off thoroughly with the pressure washer.\u003c\/p\u003e\n\u003cp\u003eIn self-service wash bays, 1:300 is enough — that's the high-volume dilution and it cuts product use noticeably over a full year. For wheel cleaning you work at 1:3 to 1:10, sprayed straight onto the cold dry wheel, left to dwell for 1 minute at most, then rinsed. Important: don't use it on hot brake discs or warm wheels. The heat speeds up the reaction in an uncontrolled way and raises the risk of dulling on painted alloy wheels.\u003c\/p\u003e\n\u003cp\u003eFor wash tunnels with conveyor lines you typically run 1:100 to 1:200. Dwell time in the tunnel is usually 30 to 60 seconds, which still keeps you safely inside the VDA-B limit of 1 minute. The higher dilution cuts foam volume at the spray arch but keeps enough cleaning power thanks to the high active-ingredient concentration. With high vehicle throughput it pays to switch to the 225 kg container — a better price per litre of concentrate.\u003c\/p\u003e\n\u003cp\u003eFor copolymer de-waxing — stripping old preservatives before a fresh sealant — 1:5 to 1:10 is the right dilution.

No snow foam replacement.\u003c\/h3\u003e\n\u003cp\u003eThe Koch Chemie Vorreiniger B is not a mild foam pre-cleaner for coating-protected vehicles. pH 13.1 is workshop level — strong, uncompromising, but sensitive in use.\u003c\/p\u003e\n\u003cp\u003eIts strength is on heavily soiled vehicles with insect, bird-dropping and road residue after a long motorway run or after winter. It also works reliably on baked-on brake dust on steel wheels and on alkali-resistant painted alloy wheels. The foam is functional — not the show foam you get from classic snow-foam products, but a working foam that clings to vertical panels.\u003c\/p\u003e\n\u003cp\u003eNow the honest read on the limits. First, the Vorreiniger B is not friendly to active ceramic coatings. Used regularly on coating-protected vehicles it breaks the coating down faster than a pH-neutral pre-wash foam does. For vehicles with an active coating, the milder Pre-Foam efficient is the better call. Second, don't use it on polished aluminium or chrome surfaces — despite the corrosion inhibitors, pH 13.1 can dull untreated light metals. The inhibitors protect anodised alloy, not bare alloy.\u003c\/p\u003e\n\u003cp\u003eThird: it is not paint-surface gentle in the sense of a hand-wash chemistry. If you look after your new car with the two-bucket method and a mild car shampoo, you don't need a Vorreiniger B in the garage. Its job starts where hand washing no longer cuts it — on heavily soiled vehicles, commercial fleets, utility vehicles and construction machinery.\u003c\/p\u003e\n\u003cp\u003eProtective gear is a must, not optional. Nitrile gloves and safety glasses when mixing and applying. On skin contact, rinse straight away with plenty of water and remove residue with mild soap. Never leave the concentrate bottle open — the fumes from the alkaline cleaner irritate airways and mucous membranes on longer exposure. Close it well after use and store it frost-free and dark.\u003c\/p\u003e\n\u003cp\u003eThe material compatibility of the Vorreiniger B has clear limits. Allowed: steel, anodised aluminium, alkali-resistant painted surfaces, glass and standard automotive plastics. Not allowed: polished light metals, bare chrome surfaces, coloured anodised layers (risk of discolouration) and matt-painted surfaces without a protective film. When in doubt, test on an inconspicuous spot before the first application and watch it for 3 minutes — it costs little time and saves expensive damage.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-vorreiniger-b-vb-vorreiniger_ergebnis.jpg?v=1776199899\" alt=\"Koch-Chemie Vorreiniger B workshop-grade alkaline cleaner pH 13.1\" loading=\"lazy\" style=\"width:100%;height:auto;display:block;margin:1.5em 0;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eWho the Vorreiniger B is for — from the pro to the home garage\u003c\/h3\u003e\n\u003cp\u003eThe Koch Chemie Vorreiniger B is built for pros and experienced home users with know-how in alkaline chemistry.

The first time you mix it, work with a calibrated measuring jug — go by eye and most beginners land far too concentrated, which loads the material needlessly and encourages streaking.\u003c\/p\u003e\n\u003cp\u003eIf you want a mild, coating-friendly pre-wash foam, you're better off with the Pre-Foam efficient. If you supply express wash lines with extremely short dwell times, reach for the Pre-Wash B.
