The high-alkaline pH breaks down polymerised greases and oils that heat has baked onto metal surfaces.

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 Green Star is a broader all-purpose cleaner — for vehicle surfaces, engines, wheels and floors, but without that specific slip-resistant property.

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. 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 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 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.

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. If you need the strongest cleaner for baked-on oil and grease residue on engines and chassis, take the Copo Star BMP-T.
