An alkaline intensive cleaner with pH 12.5 that chemically dissolves oils, greases, nicotine, soot, and discoloration on textiles, plastics, and industrial surfaces – dilutable as a concentrate from 1:5 to 1:50. Not suitable for soft-touch surfaces, leather, and painted surfaces.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003e\u003cstrong\u003eKoch-Chemie Mzr\u003c\/strong\u003e is an alkaline cleaner concentrate from Koch-Chemie that chemically dissolves stubborn organic dirt from pores and fibers. The high pH value of 12.5 in the concentrate saponifies fats and oils through alkaline hydrolysis – a process that pH-neutral cleaners cannot chemically achieve. Diluted to 1:10, the pH value is around 11, which is sufficient for most vehicle interior surfaces. Koch-Chemie has given the cleaner an official Daimler approval, making it a standard product in detailing shops and workshops.\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 open door of a black Mercedes-AMG GT in the warehouse workshop\" width=\"900\" loading=\"lazy\"\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDilutable from 1:5 to 1:50 – a concentrate for every type of dirt.\u003c\/strong\u003e For heavy soiling such as engine oil or nicotine residue, use a 1:5 dilution. For regular interior cleaning, 1:20 to 1:50 is sufficient. 1 liter of concentrate yields 21 liters of working solution when diluted 1:20 – at a purchase price of €7.67, that's €0.37 per liter of ready-to-use cleaning solution.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDissolves what pH-neutral cleaners leave behind.\u003c\/strong\u003e Nicotine, greasy fingerprints on headliners, ingrained discoloration on light upholstery – these are the cases where Mzr truly shines. The alkaline formulation saponifies fatty acids and emulsifies oil residues, rather than just displacing them on the surface. Where a neutral \u003ca href=\"\/en\/products\/koch-chemie-allround-surface-cleaner-asc-allzweckreiniger\"\u003eall-purpose cleaner\u003c\/a\u003e requires two passes, Mzr only needs one.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDaimler approval for workshop use.\u003c\/strong\u003e The official approval confirms material compatibility on factory-installed textiles and plastics from Mercedes-Benz. Detailing shops, fleet managers, and independent workshops therefore use this cleaner as a standard interior cleaner – one concentrate for the entire vehicle fleet instead of multiple specialized products.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003ePractical tip from Detailing1:\u003c\/strong\u003e Never spray Mzr undiluted onto surfaces – pH 12.5 in the concentrate attacks sensitive plastics and pigments. Always dilute it in the spray bottle first and start with 1:10. If that's sufficient, reduce the dosage to 1:20 next time. The most common mistake in practice: working with too strong a concentration and then getting white spots on dark plastics because the alkalinity attacks the surface structure. Two passes with 1:10 will produce a better and more even result than one pass with 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 individually for each application. This fundamentally distinguishes it from ready-to-use interior cleaners like the \u003ca href=\"\/en\/products\/koch-chemie-multi-interior-cleaner-innenraumreiniger-750ml\"\u003eKoch-Chemie MultiInteriorCleaner\u003c\/a\u003e, which come with a fixed, unchangeable concentration.\u003c\/p\u003e\n\n\u003cp\u003eFor headliners with nicotine residue or discolored fabric upholstery, use a 1:5 to 1:10 dilution. Spray the solution evenly, let it work for 1-3 minutes, and then work it in with a soft detailing brush in circular motions. Mzr chemically dissolves the dirt, and the brush transports it out of the fibers. Afterwards, remove the dissolved dirt with a clean microfiber cloth or a wet vacuum cleaner. For headliners, a wet vacuum cleaner is mandatory – too much standing moisture can loosen the textile adhesive and cause the headliner to detach.\u003c\/p\u003e\n\n\u003cp\u003eFor everyday interior cleaning – dashboard, center console, door panels – a dilution of 1:20 to 1:50 is sufficient. At this concentration, Mzr is gentle enough for most hard plastics. The surface becomes clean without leaving a greasy film.\u003c\/p\u003e\n\n\u003cp\u003eAfterwards, you can directly apply a plastic dressing – Mzr leaves no residue that would prevent adhesion. This makes it ideal for pre-cleaning before care steps. Nevertheless: On steering wheels with soft-touch coating and rubberized grips, even the weakest dilution is risky. In these cases, it is better to use a pH-neutral cleaner.\u003c\/p\u003e\n\n\u003cp\u003eMzr also demonstrates its versatility outside the vehicle: workshop floors with oil stains, dirty industrial machinery, discolored RV paneling. For outdoor use, dilute 1:5 to 1:10 and let it sit for 3-5 minutes. Work it in with a high-pressure cleaner or a brush, then rinse off.\u003c\/p\u003e\n\n\u003cp\u003eA detail that Koch-Chemie doesn't mention on the product page: Mzr leaves a pleasant, subtle scent on cleaned surfaces. Not an artificial air freshener, but significantly less chemical than comparable industrial cleaners. In smoker's cars, this does not cover the nicotine smell – but after cleaning, the interior smells neutral instead of chemical. This may sound like a side effect, but it is relevant in practice if you are preparing vehicles for sale or return.\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 iK Multi TR 1 spray bottle in a Mercedes-AMG GT\" width=\"900\" loading=\"lazy\"\u003e\n\n\u003ch3\u003eKoch-Chemie Mzr dissolves nicotine residue. It attacks leather.\u003c\/h3\u003e\n\u003cp\u003eOrganic contamination is the core area of Koch-Chemie Mzr: greasy fingerprints, nicotine film, soot, ink stains, and the typical discoloration on light upholstery after two years of everyday use. Here, the alkaline formulation works reliably and in one pass.\u003c\/p\u003e\n\n\u003cp\u003eThe color change from clean to dirty is immediately visible with Mzr – the microfiber cloth clearly shows what the cleaner has removed from the surface after wiping. Especially impressive on discolored, light fabric upholstery: the first wipe often shows two shades of difference. This is not marketing exaggeration, but the chemical effect of alkaline saponification, which dissolves deep-seated grease contamination that a neutral cleaner cannot reach.\u003c\/p\u003e\n\n\u003cp\u003eKoch-Chemie deliberately positions Mzr as a multi-purpose cleaner for cars, industry, and building cleaning. The container sizes demonstrate this: in addition to the 1-liter bottle, there are 11 kg, 21 kg, and 225 kg containers. This is a workshop cleaner that also works in vehicle interiors. This origin explains its strength: Mzr is formulated for industrial contamination and brings that power to the vehicle interior.\u003c\/p\u003e\n\n\u003cp\u003eWhere Mzr is not the right product: On genuine leather and artificial leather with an open-pore structure, the alkalinity can dry out the surface and leave discoloration. Leather requires a pH-adjusted leather cleaner. On soft-touch plastics and rubberized surfaces such as steering wheels or gear knobs, it leaves dull spots. An alkaline cleaner has no place on painted or foiled surfaces – even diluted to 1:50, the pH value is above 9. If you need a \u003ca href=\"\/en\/collections\/universalreiniger\"\u003euniversal cleaner\u003c\/a\u003e without risk for sensitive materials, Koch-Chemie ASC is the safer choice – pre-mixed, pH-neutral, for all surfaces.\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 discoloration on the left, rich black Alcantara on the right\" width=\"900\" loading=\"lazy\"\u003e\n\n\u003ch3\u003eOne canister of Koch-Chemie Mzr. 200 liters of working solution.\u003c\/h3\u003e\n\u003cp\u003eKoch-Chemie Mzr pays off through its yield. 1 liter of concentrate, diluted 1:20, yields 21 liters of ready-to-use solution – enough for 15-20 complete interior cleanings. At €7.67 per liter, you're looking at under €0.50 per vehicle. For those who detail regularly, the 11 kg canister is the choice: at €77.75, that's €7.07 per kilogram and around 200 liters of working solution at a 1:20 dilution.\u003c\/p\u003e\n\n\u003cp\u003eMzr is aimed at detailers, workshops, and ambitious hobbyists who want a concentrate instead of pre-mixed spray bottles. If you only occasionally clean the interior and don't want to bother with dilution, use the MultiInteriorCleaner as a ready-to-use solution. If you want to dose flexibly – stronger for a smoker's car interior, weaker for weekly maintenance – Mzr is the more economical choice.\u003c\/p\u003e\n\n\u003cp\u003eFor daily work in the workshop, we recommend the Koch-Chemie dispensing tap on the 11 kg canister: dispense concentrate into the spray bottle, fill with water, done. The 1-liter bottle is suitable for mobile use and the detailing box. Store both containers frost-free between 5 and 30 °C; the concentrate lasts 24 months unopened. Use diluted solution within 4 weeks.\u003c\/p\u003e\n\n\u003cp\u003eA safety note at the end: Mzr is classified as corrosive (H314) and bears the signal word \"Danger\". Always wear protective gloves and safety goggles when using the concentrate. In the usual working dilution of 1:10 to 1:20, the risk is significantly lower, but prolonged skin contact should still be avoided. The safety data sheet can be downloaded from the product page.\u003c\/p\u003e\n\n\u003cp\u003eIn summary: Koch-Chemie Mzr is not an everyday cleaner for a quick wipe. It is a tool for detailing where deep cleaning is required – smoker's cars, used car detailing, workshop floors, industrial machinery. Those who have these use cases and are willing to deal with dilution and protective equipment will get a concentrate that is hard to beat at costs under €0.50 per vehicle.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-mehrzweckreiniger-mzr-universalreiniger_lineup.png?v=1776196804\" alt=\"Koch-Chemie Mzr 1 liter bottle and 11 kg canister on paving stones in front of a warehouse with a Mercedes-AMG GT\" width=\"900\" loading=\"lazy\"\u003e","brand":"Koch-Chemie","offers":[{"title":"1000ml","offer_id":48762462536015,"sku":"D1-KCX-86001","price":6.85,"currency_code":"GBP","in_stock":true},{"title":"2x 1000 ml","offer_id":49536037454159,"sku":"D1-KCX-86001_2","price":13.44,"currency_code":"GBP","in_stock":true},{"title":"3x 1000 mL","offer_id":49536037486927,"sku":"D1-KCX-86001_3","price":19.95,"currency_code":"GBP","in_stock":true},{"title":"11kg","offer_id":48762460307791,"sku":"D1-KCX-86011","price":69.52,"currency_code":"GBP","in_stock":true},{"title":"21kg","offer_id":49536024772943,"sku":"D1-KCX-86021","price":127.9,"currency_code":"GBP","in_stock":true},{"title":"225kg","offer_id":49536024805711,"sku":"D1-KCX-86225","price":1345.92,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-mehrzweckreiniger-mzr-universalreiniger.png?v=1714922290","url":"https:\/\/detailing1.co.uk\/en\/products\/koch-chemie-mehrzweckreiniger-mzr-universalreiniger","provider":"Detailing1","version":"1.0","type":"link"}
