A water-based, silicone-free polymer preservation for engines, ancillaries, housings and rubber hoses that forms a permanently elastic protective film up to 250 °C and carries the Daimler factory approval (GOTIS P 00.16 – 02.0).

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

The approval checks compatibility on EPDM coolant hoses and PA, PP and ABS covers under 90–110 °C sustained load — that's why brand workshops reach for this product instead of any random engine-shine spray.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSilicone-free and propellant-free.\u003c\/strong\u003e The water-based polymer carrier holds no volatile silicone oils (critical near paintwork — think fisheyes) and no aerosol (no butane\/propane propellants). VOC content about 3 %, labelling required under GHS07, but not flammable. That cuts the risk on jobs done right there in the shop considerably.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e3 to 8 months of protection, 50–200 ml per engine bay.\u003c\/strong\u003e A 500 ml spray bottle lasts for 2 to 10 full treatments depending on engine size, which works out to 1 to 3 years of car care day-to-day. In the 5 L pro canister the price per litre drops noticeably — that version is built for detailing shops, fleet care and high-mileage households. 20 and 200 litre containers exist for industrial customers.\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 The most common mistake with Motorplast isn't too little, it's too much. Lay down puddles instead of a fine mist and you stretch the drying time well past the usual 6 to 8 hours, the polymer cures unevenly and leaves milky edges or tacky spots. The clean routine: let the engine cool to hand-warm, pre-clean with \u003ca href=\"\/products\/koch-chemie-green-star-gs-universalreiniger\"\u003eGreen Star\u003c\/a\u003e at 1:10, rinse off with a soft water jet, mist Motorplast thinly into the still-wet bay, close the bonnet and let it sit overnight. Tap any leftover pools the next morning with a dry microfibre cloth. It's self-levelling — no working in with a pad needed.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eSpray it on wet. Bonnet shut. Dry overnight.\u003c\/h3\u003e\n\n\u003cp\u003eYou spray Motorplast onto the pre-cleaned, still-wet engine bay because the residual water carries the polymers right into the tight gaps before the product itself pushes it back out. That's pro technique straight from the Daimler factory-norm test, not a marketing slogan.\u003c\/p\u003e\n\n\u003cp\u003eBefore you apply, let the engine cool down — hand-warm is ideal, boiling hot is not. On a block sitting at 130 °C oil temperature after a motorway run, the water-glycol-ether mix flashes off instantly and burns the polymers into the plastic as streaks. The officially approved heat window is 250 °C component temperature — that's for the cured film, not for the moment you apply it.\u003c\/p\u003e\n\n\u003cp\u003eFor a mid-size car, reckon on 50 to 200 ml. Work sparingly from about 20 cm away with the spray head and go systematically from back to front — valve cover, fuse box, then intake manifold, then the visible hoses and seals. You can reach awkward spots with a Cyclone or Tornador gun at 4 to 6 bar; in the home garage the supplied spray head does the job. Keep the mist away from open intake tracts and mass airflow sensors — those hot-wire sensors react badly to polymer coatings.\u003c\/p\u003e\n\n\u003cp\u003eOnce it's on, close the bonnet and let it sit 6 to 8 hours, ideally overnight. Day-one test: check the next morning whether any pools or drips are still holding. If so, tap them with a dry microfibre cloth — don't rub. The film is self-levelling and needs no mechanical spreading.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-motorplast-mp-motorkonservierung_anwendung.png?v=1777464474\" alt=\"Koch-Chemie Motorplast Mp being sprayed onto a wet engine bay Detailing1\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003ePlastic, rubber, ancillaries. Never the drive belt.\u003c\/h3\u003e\n\n\u003cp\u003eMotorplast is approved for the typical engine-bay materials: PA, PP and ABS plastic covers, EPDM rubber hoses, seals and metal ancillaries in aluminium or steel. On these substrates the permanently elastic polymer film forms, holding off dirt build-up by months and slowing road-salt corrosion.\u003c\/p\u003e\n\n\u003cp\u003eThe hard limits are friction- and safety-critical. Drive belts, V-belts and pulleys are off-limits — the polymer layer cuts the grip friction, the belt slips and worst case the alternator drops out. For the same reason, keep it off brake components, brake disc faces and the pedals. On body paint, overspray leaves streaks and is pointless there anyway — Motorplast is no paint sealant. Any mist that lands on an inner wing or bumper edge, wipe it off straight away with a damp microfibre.\u003c\/p\u003e\n\n\u003cp\u003eIf too much product did end up in the bay and milky streaks have formed, a stripping routine with an alkaline cleaner sorts it: spray \u003ca href=\"\/products\/koch-chemie-green-star-gs-universalreiniger\"\u003eGreen Star\u003c\/a\u003e on generously at 1:10, foam it up with a soft detailing brush, rinse off. The cross-linked polymers break down under the APC and the film comes off without residue. After that you can lay on a second, thinner coat of Motorplast.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-motorplast-mp-motorkonservierung_detail.png?v=1777464492\" alt=\"Koch-Chemie Motorplast Mp permanently elastic protective film on a plastic cover\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eSpring and autumn. Twice a year is plenty.\u003c\/h3\u003e\n\n\u003cp\u003eThe typical rhythm for Motorplast is twice a year — once in spring after the salt season and once in autumn before winter sets in. In between, dusting the plastic covers with a microfibre cloth is enough. Detailing shops slot the product into their winter-check packages, because 5 minutes of work buys 6 months of corrosion protection.\u003c\/p\u003e\n\n\u003cp\u003eThe 500 ml spray bottle is the right call for a single car or for hobbyists getting seasonal vehicles like convertibles or classics ready for spring. Per treatment 50 to 100 ml — so the bottle carries you across several seasonal cycles. For multi-car households or commercial detailers the 5 litre canister pays off: noticeably lower price per litre, just decant it into a separate \u003ca href=\"\/collections\/koch-chemie\"\u003eKoch-Chemie\u003c\/a\u003e cylinder bottle with a spray head. 20 and 200 litre containers are pure industrial variants for workshop groups and OEM supplier chains.\u003c\/p\u003e\n\n\u003cp\u003eStorage is fussier than with many other detailing products: Motorplast keeps at +5 °C to +25 °C, frost-free and out of the sun. Frost breaks down the polymer emulsion and the product won't spray cleanly afterwards. It's fine in the garage or the stockroom — just don't let it overwinter in the boot.\u003c\/p\u003e\n\n\u003cp\u003eApply Motorplast properly once — cold engine bay, wet pre-clean, thin mist, bonnet shut overnight — and you get an engine bay that looks the same after winter as it did before. That's the Detailing1 standard: not shine in the shop window, but an engine that still runs like new after three winters. For full seasonal care you pair Motorplast with \u003ca href=\"\/products\/koch-chemie-green-star-gs-universalreiniger\"\u003eGreen Star\u003c\/a\u003e as the pre-cleaner — that's the complete engine-bay workflow in under 30 minutes per car.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-motorplast-mp-motorkonservierung_lineup.png?v=1777464511\" alt=\"Koch-Chemie Motorplast Mp 500ml spray bottle and 5 litre canister Detailing1\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n","brand":"Koch-Chemie","offers":[{"title":"500ml","offer_id":48498577211727,"sku":"D1-KCX-236500","price":9.99,"currency_code":"EUR","in_stock":true},{"title":"2x500ml","offer_id":49763373973839,"sku":"D1-KCX-236500_2","price":19.58,"currency_code":"EUR","in_stock":true},{"title":"3x500ml","offer_id":49763374006607,"sku":"D1-KCX-236500_3","price":29.07,"currency_code":"EUR","in_stock":true},{"title":"5 liters","offer_id":48498577277263,"sku":"D1-KCX-236005","price":65.49,"currency_code":"EUR","in_stock":true},{"title":"20 liters","offer_id":49763374039375,"sku":"D1-KCX-236020","price":244.49,"currency_code":"EUR","in_stock":true},{"title":"200 liters","offer_id":49763374072143,"sku":"D1-KCX-236200","price":2602.99,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-motorplast-motorkonservierung.jpg?v=1710780165"},{"product_id":"koch-chemie-top-star-ts-innenraum-kunststoffpflege","title":"Top Star \"Ts\" Interior Plastic Care","description":"\u003ch2 id=\"speakable-headline\"\u003eSatin-matt shine in the interior with the Koch-Chemie Top Star \"Ts\"\u003c\/h2\u003e\n\n\u003cblockquote id=\"speakable-summary\"\u003e\n  \u003cp\u003e\u003cem\u003eWhat is the Koch-Chemie Top Star \"Ts\"?

We often get messages like \"the glass cleaner leaves streaks\". Usually the wiping happened on a warm pane in the sun, where the film flashes off before the cloth lifts it. Work on a cold pane in the shade and go by the two-cloth rule: lift the dirt with 1 damp cloth, then buff dry in straight passes with a dry glass cloth. More product doesn't clean better, it tends to leave edges.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eSpray it on neat, pull it off streak-free with two cloths\u003c\/h3\u003e\n\u003cp\u003eYou spray the Glass Cleaner \"Gc\" on neat from 20 to 30 cm onto the cold, shaded pane and pull it off with a dry microfibre glass cloth in straight passes. That way no film of water is left standing to flash off.\u003c\/p\u003e\n\u003cp\u003eOutside, the cleaner lifts bug splatter, pollen and the greasy road film. With a baked-on bug front, let the cleaner soak for about 30 seconds and only then pull it off, rather than scrubbing harder. That goes easy on the glass and on the wiper blades.\u003c\/p\u003e\n\u003cp\u003eInside, it's about the greasy film off-gassing from the dash and about nicotine. If you want to \u003cem\u003eclean your car windows from the inside\u003c\/em\u003e, spray sparingly onto the cloth rather than straight onto the glass, so no mist drifts onto a display or a vent. With a \u003ca href=\"\/products\/the-rag-company-diamond-280-gsm-mikrofaser-glastuch\"\u003emicrofibre glass cloth\u003c\/a\u003e especially, the cloth quality decides whether the loosened dirt gets picked up or just smeared around.\u003c\/p\u003e\n\u003cp\u003eThe second, bone-dry pass over the finished pane lifts the last haze out. That's exactly the step most people skip, and that's exactly where you get the streaks you spot later in backlight. A good glide additive makes the difference here between any old cleaner and a real car glass cleaner.\u003c\/p\u003e\n\u003cp\u003eWhy the cold pane? The additive only works its glide as long as the film is liquid. On hot glass the water flashes off too fast, the cleaner grabs and the cloth just pushes the dirt around. In the shade or early in the morning you've got that window of time. Wash new microfibre cloths once without softener before they ever touch glass too, otherwise they carry sizing onto it that pulls streaks all by itself.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-glass-cleaner-gc-glasreiniger_anwendung.png?v=1780006597\" alt=\"Koch-Chemie Glass Cleaner Gc being sprayed on a car window and pulled off with a microfibre cloth\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eWhat the Gc is built for and what it isn't\u003c\/h3\u003e\n\u003cp\u003eThe Gc cleans glass, it doesn't seal it and it doesn't belong in the washer reservoir.

One verified customer puts it well: with stubborn dirt you need 2 to 3 passes rather than scrubbing under pressure. A short soak and another pull is gentler and quicker in the end, because you avoid scratches you'd have to polish out later.\u003c\/p\u003e\n\u003cp\u003eAnti-fog protection is something the Gc deliberately leaves out. It gets you clean, clear glass, but against fogging from the inside only an anti-fog treatment helps for the long run. Clean glass does fog up far more evenly though, and so far less of a bother than a greasy film.\u003c\/p\u003e\n\u003cp\u003eBeyond the car the Gc cleans mirrors, interior and exterior, motorcycle visors, instrument glass and smooth surfaces around the house like tiles or stainless steel. The only place to be careful is on matte anti-glare nav and instrument displays: there you always spray onto the cloth and work with little pressure, so the coating doesn't suffer. On clear glass and glossy plastic headlights it works with no restrictions.\u003c\/p\u003e\n\u003cp\u003eIn a smoker's car a tacky nicotine film settles on the inside glass, scattering the light and making everything look yellowed. Here you work in 2 layers: lift and roughly take it off first, then buff dry with a fresh cloth.

The commuter grabs the 1-litre bottle, the detailer the 10 or 20-litre container.\u003c\/p\u003e\n\u003cp\u003eGlass cleaners are in highest demand in spring: pollen and bug season drives demand about 40 percent over the quiet winter level. If you've got a bottle in the boot now, you clean the windscreen on the road instead of driving into the low sun with a pollen film and streaks.\u003c\/p\u003e\n\u003cp\u003eDay-to-day the difference shows in the details: no streaks in backlight, no haze on the inside glass that turns oncoming headlights into stars at night. If you drive a lot with the sun low or in the dark, you notice a streak-free pane straight away.\u003c\/p\u003e\n\u003cp\u003eThe Gc is fuss-free on cost: 1 litre ready-to-use lasts many weeks of commuter life depending on how much you spray, and decanting the 10-litre container into a spray bottle costs you far less per litre. Store the cleaner frost-free and the spray function stays reliable across the whole shelf life. An opened bottle in the car survives the summer heat better if it isn't left baking in full sun all the time.\u003c\/p\u003e\n\u003cp\u003eHow often you clean depends on your driving: if you commute daily, keep the windscreen clear inside about every 2 weeks and outside as needed with pollen or bugs. High-mileage drivers and detailers with several cars a day get the most out of the big container and a spray bottle fixed to the trolley. That turns reaching for the car glass cleaner into routine rather than the exception.\u003c\/p\u003e\n\u003cp\u003eThe one trick hardly anyone does and that stops most streaks: clean the inside first, then the outside, and pull horizontally inside, vertically outside. If a streak is left after cleaning, the direction tells you straight away whether it's on the inside or the outside, and you only fix it there. That saves you the third pass and the guessing.

Lay Leather Star on thick and you get a shiny halo on the bolsters and a greasy, slippery film on the cushion. The rule we use in the bay: 15 to 20 pea-sized drops on a microfibre applicator per seat cushion, worked in circular motions and thin as a whisper. With perforated leather, follow up with a soft brush over the holes — otherwise the product dries white inside them. After 5 to 10 minutes' dwell, buff the shine off with a dry microfibre — that's when the OEM look lands.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003ePol Star first, then Leather Star.

The hydrophobic emulsion can't enter a water-saturated fibre structure — it just sits on the surface as a streaky film. On a dirty seat the other way round, the dressing locks sweat and skin oils into the leather pores — a mistake that only shows up after weeks, but then for good.\u003c\/p\u003e\n\n\u003cp\u003eOnto clean, dry leather go 15 to 20 pea-sized drops per seat cushion on a soft microfibre applicator. Work in circular motions across the panel without running over the seat edges.\u003c\/p\u003e\n\n\u003cp\u003eA bolster needs less than a cushion, perforated leather less than smooth leather with a dense grain pattern. On the centre console and the leather steering wheel one single drop per part is enough.\u003c\/p\u003e\n\n\u003cp\u003eWith pigmented aniline leather (often in BMW Individual, Bentley or Rolls-Royce) you work fast, because the open-pore fibre pulls the emulsion in quicker — uneven saturation leaves tonal patches.

On convertibles and cars with light leather the UV block carries the heavy lift — without active protection, light aniline leather can fade visibly in a single summer of convertible use.\u003c\/p\u003e\n\n\u003cp\u003eThere are hard limits too. Alcantara isn't leather, it's a synthetic microfibre fabric of polyester and polyurethane — the greasing emulsion glues the microfibres together permanently and triggers pilling. For Alcantara the right tool stays the bare \u003ca href=\"\/products\/koch-chemie-pol-star-po-textil-leder-alcantarareiniger\"\u003ePol Star\u003c\/a\u003e without a follow-up dressing. With vinyl-coated faux leather you can dress the surface, but the material doesn't take up the re-greasing components — a thorough wipe-down afterwards is non-negotiable. On already-cracked patent-leather surfaces you need a repair product from the COLOURLOCK line, not a dressing.\u003c\/p\u003e\n\n\u003cp\u003eFor pro detailers and shops there's one more thing: Leather Star carries 12.35 percent VOC (Swiss VOC-CH regulation). With several applications a day in closed reconditioning bays, ventilation is required — doors wide open or extraction running — plus nitrile gloves because the carriers de-grease your skin (EUH066 in the SDS).\u003c\/p\u003e\n\n\u003cp\u003eIf you've got classic smooth or genuine leather and want a ready-to-use top-up every few months, Leather Star is the call. Pro detailers running ten cars a week have the concentrate sibling in COLOURLOCK Leather Care — same maker, same formula family, different dilution logic.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-leather-star-ls-lederpflege_workflow.png?v=1777309068\" alt=\"Workflow with Koch-Chemie Pol Star Po and Leather Star Ls on a Porsche 911 interior clean-up\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eThree bottle sizes, three buyer profiles.\u003c\/h3\u003e\n\n\u003cp\u003eThe 1-litre bottle at €14.23 is the easy starting point for one or two cars in a private household. With care intervals every four to six months it works out to about ten full car interiors — three to four years for a single car. The bottle itself stays good for 24 months after opening, frost-free and sealed in the original container.\u003c\/p\u003e\n\n\u003cp\u003eThe 2×1 L set at €27.89 saves you roughly 50 cents per litre versus the single bottle. It fits households that look after a car and leather furniture together — high-end manufacturers like De Sede, Vitra or USM Haller build their seating with aniline or semi-aniline leather.\u003c\/p\u003e\n\n\u003cp\u003eFor furniture, once or twice a year after a thorough dust-down is enough, because living-room furniture doesn't take the UV and temperature beating a car interior does. The colour-deepening effect comes out strongest on open-pore aniline.\u003c\/p\u003e\n\n\u003cp\u003eThe 3×1 L bundle at €41.41 fits smaller detailers, shops without 5-litre storage and fleets of three to five vehicles. Per litre you're at about €13.80, which drops the per-seat anchor to around €1.30. If you burn through a full 1 L bottle per quarter, that's the volume that turns over without storage risk — four to five jobs a month.\u003c\/p\u003e\n\n\u003cp\u003eSeasonally, two windows make sense to buy: spring detailing between March and May when convertibles come out of winter storage, and the autumn impregnation between October and November before the dry heating air hits the interior. Both peaks land in DACH search behaviour too, and they're the weeks when Leather Star tends to be most readily available.\u003c\/p\u003e\n\n\u003cp\u003eThe Detailing1 tip the maker doesn't write down: the smell of a fresh application is creamy-chemical and fades within about 48 hours. If you're picking up a passenger on the same day, ventilate well beforehand or do the job at the weekend with the doors open. On perforated seats with ventilation, one more thing: leave the seat-vent switch off until the next morning — otherwise the ventilation pulls the smell into the cushion fill, and it sticks around noticeably longer than the standard 48 hours.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-leather-star-ls-lederpflege_lineup.png?v=1777309078\" alt=\"Koch-Chemie Pol Star Po and Leather Star Ls 1000 ml with microfibre cloths and detail brush\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e","brand":"Koch-Chemie","offers":[{"title":"1000 ml \/ 1 liter","offer_id":48762445168975,"sku":"D1-KCX-238001","price":12.99,"currency_code":"EUR","in_stock":false},{"title":"2x 1000 mL","offer_id":49725075030351,"sku":"D1-KCX-238001_2","price":25.46,"currency_code":"EUR","in_stock":false},{"title":"3x 1000 mL","offer_id":49725075063119,"sku":"D1-KCX-238001_3","price":37.8,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-leather-star-ls-lederpflege_1000ml.png?v=1713691853"},{"product_id":"koch-chemie-hydro-plast-care-hpc-kunststoffpflegekonzentrat-wassserverduennbar","title":"Hydro Plast Care \"Hpc\" Plastic Care Concentrate (Water-Dilutable)","description":"\u003ch2 id=\"speakable-headline\"\u003eKoch-Chemie Hydro Plast Care cares for plastic and rubber with an adjustable gloss level\u003c\/h2\u003e\n\n\u003cblockquote id=\"speakable-summary\"\u003e\n  \u003cp\u003e\u003cem\u003eWhat is Koch-Chemie Hydro Plast Care?

The care layer then sits on top of the dirt instead of lifting it, the surface looks fresh but pulls dust back in twice as fast within a few days. Degrease with APC first, wipe it dry, then spray. That way the care bonds with the plastic, not with the grime layer on top of it.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eNeat for high gloss. 1:4 for the original look.\u003c\/h3\u003e\n\u003cp\u003eYou apply Hydro Plast Care neat to tyre sidewalls and glossy exterior parts. Diluted at 1:4 it gives the matte original look for dashboards and door trims.\u003c\/p\u003e\n\n\u003cp\u003eThe dosing sets the gloss level, not how much you put on. The concentrate goes into an empty spray bottle or onto a clean sponge. Lay it down thin and even on the dry, degreased surface, let it flash off for 2 to 3 minutes and buff out with a microfibre cloth.\u003c\/p\u003e\n\n\u003cp\u003ePer car interior you'll work out around 20 to 30 millilitres at 1:4, and for neat application on four tyre sidewalls 30 to 40 millilitres covers the full set. For door seals and rubber profiles you go 1:1 and apply with an applicator brush, that keeps them supple without any shine.\u003c\/p\u003e\n\n\u003cp\u003eFor the cockpit we'd suggest 1:3 or 1:4, so the light doesn't bounce up into the windscreen and the dash doesn't look freshly oiled from the driver's seat. On bumpers and trim strips in matte plastic you work at 1:2. If you're prepping tyres for a photo shoot, apply neat to the dry sidewall and leave it for 5 minutes, no working in needed. You'll find the kit to go with it in the \u003ca href=\"\/collections\/kunststoffpflege\"\u003ePlastic Care category\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003cp\u003eMix the amount you need for the day fresh, not in advance. A diluted solution in an open spray bottle pulls in air after 5 to 7 days and loses gloss, because the surfactant structure slowly separates out. For commercial use, write the mixing date on the bottle with a waterproof marker and bin the leftovers after a week, that's cleaner than the \"give it another good shake\" approach.\u003c\/p\u003e\n\n\u003cp\u003eFor the order in the workflow: vacuum the interior first, then degrease, then apply Hydro Plast Care. Outside it goes on after the wash and before the tyre care. If you do the tyre care first and then treat the bumper next to it with the gloss coat, you risk overspray on tyre sidewalls that haven't dried off yet, the result is patchy and won't just wipe back to right.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-hydro-plast-care-hpc-kunststoffpflegekonzentrat-wassserverduennbar_anwendung_f49ebe99-a6d7-4a04-89f7-a56830465279.png?v=1778657765\" alt=\"Koch-Chemie Hydro Plast Care applied to a cockpit with a microfibre cloth\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eSolvent-free means UV protection without the chemical smell.\u003c\/h3\u003e\n\u003cp\u003eHydro Plast Care lays a thin, flexible film as a UV barrier over the plastic. That slows fading and embrittlement, which tend to show up on black dash parts after two or three summers.\u003c\/p\u003e\n\n\u003cp\u003eBlack plastic in the interior hits surface temperatures of 70 to 90 °C in summer sun. Under that load the plasticisers migrate to the surface and get broken down by UV, the plastic goes grey, rough and starts to creak. The care layer from Hydro Plast Care doesn't replace those lost plasticisers, but it slows the UV reaction down.\u003c\/p\u003e\n\n\u003cp\u003eBecause the formula does without classic solvents, no aggressive fumes evaporate as you apply it. The product is cleared for the interior, no smell to deal with on the first drive home and no irritation for people who react to volatile hydrocarbons. The protective layer cuts the static charge on smooth plastic surfaces noticeably, which slows how fast dust settles between care intervals.\u003c\/p\u003e\n\n\u003cp\u003eThe clear limits: Hydro Plast Care isn't meant for leather, Koch-Chemie has its own products for that with Pol Star \"Po\" and Leather Star \"Ls\". The concentrate doesn't get on with fabric seats, headliners or Alcantara either, because the care film would gum up the textile fibres.\u003c\/p\u003e\n\n\u003cp\u003eLet hot plastic parts after summer drives cool down for at least 15 minutes, otherwise the product burns in streaky and you end up buffing it off again.

One bottle neat, the same bottle diluted, one purchase covers interior and exterior.\u003c\/p\u003e\n\n\u003cp\u003eIt's less of a fit for occasional users who give their car a thorough detail once or twice a year. A concentrate only pays off with regular use: if you rarely dilute, you lose the price edge to shelf life, because an opened bottle can go cloudy after about 24 months. In that case a ready-dosed product from our \u003ca href=\"\/collections\/koch-chemie\"\u003eKoch-Chemie category\u003c\/a\u003e is the smarter buy.\u003c\/p\u003e\n\n\u003cp\u003eA verified customer review of the 5-litre canister puts this honestly: if you're used to the Klassik version ready-to-use, the dilution step feels like extra work, and for that type of user Plast Star \"Pss\" is the better fit, not the concentrate. A second voice from the 1-litre bottle, by contrast, makes a point of the yield. Both bits of feedback show the same thing: the dilution curve isn't a blanket upside, it's a way of working that has to fit your workflow.\u003c\/p\u003e\n\n\u003cp\u003eThe four pack sizes cover different use profiles. The 1-litre bottle is the way in for one car and gives you around 5 litres of ready-to-use care after 1:4 dilution, enough for 25 to 30 cockpit passes. The 2×1-litre set and the 3×1-litre set are meant as a stash for detailing enthusiasts who run the family car, the second car and the seasonal car side by side.\u003c\/p\u003e\n\n\u003cp\u003eThe 5-litre canister is clearly worked out for detailers, workshops and fleet care and pulls the per-litre price down noticeably, at full 1:4 dilution it works out to 25 litres of ready care. If you're emptying the canister commercially, fill the spray bottle up front with the amount you need for the day and reseal the main container straight away, so the emulsion doesn't pull in air for nothing.\u003c\/p\u003e\n\n\u003cp\u003eOur strongest hands-on insight from our own details: applying Hydro Plast Care straight after the wash onto lightly damp-wiped plastic saves you a whole step compared to solvent-based classic care. The water-dilutable concentrate spreads more evenly on a damp surface, as long as the surface is degreased and not dripping wet.\u003c\/p\u003e\n\n\u003cp\u003eStore frost-free between 5 and 30 °C and use it up within 24 months of opening, that way the emulsion stays stable and you hold the set gloss level for the whole life of the container. Below freezing the emulsion separates, and a shake won't fully bring the mix back together after that.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-hydro-plast-care-hpc-kunststoffpflegekonzentrat-wassserverduennbar_lineup.png?v=1778625693\" alt=\"Koch-Chemie Hydro Plast Care 1L bottle, 2-pack, 3-pack and 5L canister lineup\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n","brand":"Koch-Chemie","offers":[{"title":"1000ml","offer_id":49855770689871,"sku":"D1-KCX-476001","price":12.49,"currency_code":"EUR","in_stock":true},{"title":"2x 1000ml Set","offer_id":49855770722639,"sku":"D1-KCX-476001_2","price":27.42,"currency_code":"EUR","in_stock":true},{"title":"3x 1000ml Set","offer_id":49855770755407,"sku":"D1-KCX-476001_3","price":40.71,"currency_code":"EUR","in_stock":true},{"title":"5 liters","offer_id":49920342196559,"sku":"D1-KCX-476005","price":44.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-hydro-plast-care-hpc-kunststoffpflegekonzentrat-wassserverduennbar_4b21292d-a5ac-42bb-8ebf-3e5eaeb10212.png?v=1778623453"}],"url":"https:\/\/detailing1depot.com\/collections\/koch-chemie-innenraum-finish.oembed","provider":"Detailing1","version":"1.0","type":"link"}
