A pH-neutral cleaner concentrate from Koch-Chemie and COLOURLOCK for fabric, Alcantara and pigmented smooth leather, dosed 1:5 to 1:20.

Since Koch-Chemie took over leather specialist COLOURLOCK in 2025, the classic Pol Star carries over with the same formula under the new label.\u003c\/p\u003e\n\n\u003cp\u003eSame chemistry, new branding: the leather know-how now lives in the product name, but production stays at Koch-Chemie in Unna. If you knew the old Pol Star Po, you're getting the same formulation here — just as a more economical concentrate rather than ready-to-use. The 1-litre bottle gives you around 11 litres of working solution at 1:10, which puts the per-use cost below any comparable pre-mixed interior cleaner.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-colourlock-pol-star-reinigerkonzentrat-textil-leder-alcantara_hero.png?v=1776185413\" alt=\"COLOURLOCK Pol Star cleaner concentrate on workshop trolley next to BMW M3 interior\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThree materials, one bottle.\u003c\/strong\u003e Pol Star pulls dirt off textile fabrics, Alcantara and pigmented smooth leather. pH 7, no acids or alkalis, no bleach.

A lot of detailers start at 1:5 — but the stronger mix leaves surfactant residue that dries as pale rings. Start at 1:10 and only step up to 1:5 if the dirt won't come out on the first pass. On leather you stay at 1:20, full stop. Use distilled water — tap water brings limescale rings with it, particularly nasty on dark Alcantara.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003e1:10 as standard. 1:20 on leather.\u003c\/h3\u003e\n\u003cp\u003ePol Star gets dosed differently depending on material and dirt level. 1:10 is the all-round ratio for fabric and Alcantara at normal soiling — a 500 ml spray bottle then takes 45 ml of concentrate and 455 ml of distilled water. Vacuum thoroughly before cleaning so loose dirt doesn't get into the solution and pull streaks.\u003c\/p\u003e\n\n\u003cp\u003eFor embedded stains on carpet or footwell, drop to 1:5. On leather you stay at 1:20, because the top coat can react to higher surfactant levels with a loss of sheen. The conserver in the formula protects existing impregnations but doesn't replace a sealant after cleaning — if you want to rebuild a fabric impregnation, lay it down separately once everything is fully dry. Dwell time runs 30 to 60 seconds; longer doesn't give you more cleaning, because the surfactant action hits its plateau by then.\u003c\/p\u003e\n\n\u003cp\u003eYou apply with a fine-mist sprayer, not directly with the cloth. The fine foam needs air to work into the fibre — too much liquid floods the fabric and drags the drying time out to 12 hours. To lift it off, grab a \u003ca href=\"\/en\/products\/the-collection-mikrofasertuecher-allround-coating-300-kurzfloriges-edgeless-mikrofasertuch-300-gsm\"\u003eshort-pile microfibre cloth\u003c\/a\u003e or a wet-dry vacuum for larger upholstery work. On Alcantara, work along the fibre direction — never circular, otherwise the surface mats up visually and looks duller than before.\u003c\/p\u003e\n\n\u003cp\u003eAfter cleaning, wipe down or extract with clean water so no surfactant residue stays behind. Leftovers would act as a dust magnet and re-soil the surface faster. Work at room temperature between 15 and 25 degrees — in sun or heat the concentrate flashes off too fast and leaves rings.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-colourlock-pol-star-reinigerkonzentrat-textil-leder-alcantara_anwendung_2887a60b-7120-4b56-8839-5f9adb7e9e97.png?v=1776185956\" alt=\"Pol Star diluted 1:10 sprayed onto Alcantara seat from iK Multi spray bottle\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003ePol Star handles three materials. Two leather types it doesn't.\u003c\/h3\u003e\n\u003cp\u003ePol Star is approved for pigmented, top-coated smooth leather — that's most modern automotive leather from year 2000 onwards. The top coat insulates the cleaner from the collagen, so the surfactants pull dirt off without working into the material.\u003c\/p\u003e\n\n\u003cp\u003eOn open-pore leathers it behaves differently. Aniline, semi-aniline and nubuck have no protective pigment layer — the concentrate goes straight into the fibre and can cause staining or discolouration. For those materials, the specific Aniline \u0026 Nubuck Cleaner from the same COLOURLOCK range is the right call, formulated for exactly that case. Suede and velour fall into this category too and need a dry or enzymatic approach instead of a surfactant solution.\u003c\/p\u003e\n\n\u003cp\u003eBefore every leather job, test colourfastness on a hidden spot: wet a cotton swab with 1:20 solution, hold it on the test patch for 30 seconds, check for colour transfer. If the swab picks up colour, the leather isn't a fit for Pol Star. The manufacturer doesn't put this front and centre — but it saves you expensive mistakes, because discoloured leather usually only comes back with a full re-dye. For heavily soiled pigmented leather with embedded skin oil, go to the \u003ca href=\"\/en\/products\/koch-chemie-colourlock-leather-cleaner-strong-lederreiniger\"\u003eCOLOURLOCK Leather Cleaner Strong\u003c\/a\u003e. If you're cleaning all materials in the interior regularly, grab Pol Star. If you're specifically reconditioning soiled leather, grab the specialist.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-colourlock-pol-star-reinigerkonzentrat-textil-leder-alcantara_ergebnis.png?v=1776185960\" alt=\"Clean Alcantara seat after COLOURLOCK Pol Star clean with iK spray bottle in background\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eFor detailers, shops and weekend enthusiasts\u003c\/h3\u003e\n\u003cp\u003ePol Star fits where interior gets cleaned regularly and a concentrate makes more sense than ready-to-use sprays. Detailing shops run the 1-litre bottle and decant into their own sprayers; private users start with the 100 ml or 250 ml size for one to two cars a year. The 1-litre at 1:10 covers around 20 full interior cleans.\u003c\/p\u003e\n\n\u003cp\u003eNot the right pick if you're only doing leather — for that, the COLOURLOCK range has the dedicated Leather Cleaner in Mild and Strong grades, tuned to dirt level and leather type. It also hits limits with dried-in stains older than a week or organic spills like milk, blood or vomit — for those, enzyme cleaners work more reliably, because they break protein bonds instead of just lifting them.\u003c\/p\u003e\n\n\u003cp\u003eOn the workflow side: as a concentrate, you need a proper fine-mist spray head. The \u003ca href=\"\/en\/products\/koch-chemie-spruehkopf-spruehflasche-set\"\u003eKoch-Chemie sprayer and bottle set\u003c\/a\u003e is built for it — the Canyon CHS-3AN throws an even mist that supports fine foam build-up instead of flooding the surface. Once you're set up, a full interior clean runs 40 to 60 ml of concentrate — that's the practical gap between concentrate and ready-mix. If you run the concentrate in a shop setting, follow up with a wet-dry vacuum after cleaning to pull residual moisture out and avoid drying rings.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-colourlock-pol-star-reinigerkonzentrat-textil-leder-alcantara_lineup.png?v=1776185429\" alt=\"COLOURLOCK Pol Star in three sizes 100 ml 250 ml 1 litre on paving stone\" loading=\"lazy\"\u003e\u003c\/p\u003e\n","brand":"Koch-Chemie × COLOURLOCK","offers":[{"title":"1000 ml \/ 1 liter","offer_id":56541767369039,"sku":"D1-KCX-619-1L-01","price":10.52,"currency_code":"EUR","in_stock":true},{"title":"250ml","offer_id":56541771432271,"sku":"D1-KCX-619-250ML-01","price":6.7,"currency_code":"EUR","in_stock":true},{"title":"100ml","offer_id":56541767401807,"sku":"D1-KCX-619-100ML-01","price":5.74,"currency_code":"EUR","in_stock":true},{"title":"5 liters","offer_id":57635624288591,"sku":"D1-KCX-619-5L-01","price":45.97,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-colourlock-pol-star-reinigerkonzentrat-textil-leder-alcantara.png?v=1779136128","url":"https:\/\/detailing1.eu\/en\/products\/koch-chemie-colourlock-pol-star-reinigerkonzentrat-textil-leder-alcantara","provider":"Detailing1","version":"1.0","type":"link"}
