A 150ml pump bottle with a dilution scale up to 1:10 that transforms concentrated cleaning agents into a dry, voluminous foam — ideal for upholstery, leather, and Alcantara. Not suitable for highly acidic wheel cleaners, insect removers, solvents, or ready-to-use cleaners, as the bottle is designed for concentrated products to be diluted.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003e\u003cstrong\u003eThe Koch-Chemie Foamer Bottle\u003c\/strong\u003e is a foam dispenser from Koch-Chemie that converts concentrated cleaners into a dry, lamellar foam using an integrated mixing chamber and a pump head. The active ingredient remains on the fiber longer because the cleaning solution does not flood the surface as a spray, but rather rests as a fine-pored foam structure and dissolves the substrate layer by layer, instead of soaking it through.\u003c\/p\u003e\n\n\u003cp\u003eA volume and dilution scale is printed on the side of the bottle, clearly marking ratios from 1:1 to 1:10. First, fill with water up to the desired dilution mark, then add the concentrate — not the other way around, otherwise the cleaner will foam up during filling and you will lose volume. This sequence is the most common mistake in practice and the reason why some users report foam density problems.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScale 1:1 to 1:10 on the bottle.\u003c\/strong\u003e 150 ml of concentrate at a 1:10 ratio yields approximately 1.65 liters of ready-to-use cleaning solution — enough for four to five complete vehicles for a typical interior job with COLOURLOCK Pol Star concentrate. You don't need to carry measuring cups or syringes, and the dilution is reproducible when refilling.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDry foam instead of wet spray.\u003c\/strong\u003e The pump head creates fine-pored foam that adheres vertically to seat bolsters and door panels without soaking through. On upholstery and Alcantara, this means the active ingredient stays in the dirt instead of the foam core, and the brush works cleaner because it doesn't have to go through a layer of water.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControlled material usage.\u003c\/strong\u003e One filling of the Foamer Bottle is sufficient for the complete interior detailing of a mid-range vehicle (seats, carpet, headliner, door panels, center console) — consumption between 80 and 120 ml of diluted solution. Compared to spraying directly from a 1-liter bottle, this reduces cleaner consumption by about two-thirds.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-foamer-bottle-schaumspender-150ml_hero.jpg?v=1777826972\" alt=\"Water being filled into the Koch-Chemie Foamer Bottle, Pol Star concentrate next to it, Porsche 911 Turbo S in the background\" loading=\"lazy\" width=\"1200\"\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDetailing1 Pro Tip:\u003c\/strong\u003e The most common cause of pump mechanism failure is not a defect, but dried cleaner concentrate in the pump chamber. After each cleaning session, empty the bottle, refill it with clear tap water, and pump it empty 8 to 10 times until only water comes out. This 60 seconds of care significantly extends the life of the Foamer Bottle — a pump that dries out with cleaner residue will block the return spring and must then be manually pushed back.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eWater first, concentrate after, read the scale\u003c\/h3\u003e\n\u003cp\u003eUnscrew the pump head, fill the bottle with lukewarm tap water up to the desired dilution mark, and only then add the concentrate — such as COLOURLOCK Pol Star or \"Mzr\" all-purpose cleaner — up to the 100% mark. Replace the pump head, tip the bottle two or three times instead of shaking it to prevent premature foam from entering the pump chamber, and pre-pump three to four times until stable foam emerges.\u003c\/p\u003e\n\n\u003cp\u003eIt is important to distinguish between concentrate and ready-to-use: The classic Pol Star \"Po\" 1L already comes ready-to-use in a spray bottle and should NOT be diluted — it goes directly onto the upholstery. The Foamer Bottle is intended for the concentrate line (COLOURLOCK Pol Star, Green Star \"Gs\", \"Mzr\" all-purpose cleaner), which would not be applicable without dilution because it is too highly concentrated.\u003c\/p\u003e\n\n\u003cp\u003eThen, wipe in one direction with a damp microfiber cloth — never back and forth, as this will re-embed dissolved dirt into the fabric. For heavily soiled seat bolsters or upper backrest edges, a second pass with a reduced amount of foam is more effective than extending the dwell time of the first application, because the foam lamellae begin to collapse after 90 seconds and the active ingredient is no longer working actively.\u003c\/p\u003e\n\n\u003cp\u003eThe dilution matrix for the most common applications is as follows:\u003c\/p\u003e\n\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n\u003cth\u003eConcentrate\u003c\/th\u003e\n\u003cth\u003eDilution\u003c\/th\u003e\n\u003cth\u003eApplication Area\u003c\/th\u003e\n\u003cth\u003eDwell Time\u003c\/th\u003e\n\u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCOLOURLOCK Pol Star\u003c\/td\u003e\n\u003ctd\u003e1:10\u003c\/td\u003e\n\u003ctd\u003eUpholstery, Alcantara, Fabric seats\u003c\/td\u003e\n\u003ctd\u003e1–2 Min\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCOLOURLOCK Pol Star\u003c\/td\u003e\n\u003ctd\u003e1:5\u003c\/td\u003e\n\u003ctd\u003eSmooth leather, medium soiling\u003c\/td\u003e\n\u003ctd\u003e1 Min\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eAll-purpose cleaner Mzr\u003c\/td\u003e\n\u003ctd\u003e1:5\u003c\/td\u003e\n\u003ctd\u003eCockpit, plastic door panels\u003c\/td\u003e\n\u003ctd\u003e30 Sec\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eGreen Star Gs\u003c\/td\u003e\n\u003ctd\u003e1:10\u003c\/td\u003e\n\u003ctd\u003eGeneral interior surfaces\u003c\/td\u003e\n\u003ctd\u003e1 Min\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eAll-purpose cleaner Mzr\u003c\/td\u003e\n\u003ctd\u003e1:10\u003c\/td\u003e\n\u003ctd\u003eHeadliner, fabric headliner\u003c\/td\u003e\n\u003ctd\u003e30 Sec\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-foamer-bottle-schaumspender-150ml_anwendung.jpg?v=1777826972\" alt=\"Bubbly foam from Koch-Chemie Foamer Bottle being pumped onto a black leather upholstery sample in the Detailing1 Warehouse\" loading=\"lazy\" width=\"1200\"\u003e\n\n\u003ch3\u003eNot for acidic cleaners and not for foam cannon quantities\u003c\/h3\u003e\n\u003cp\u003eThe Foamer Bottle covers the medium dilution spectrum for interior chemicals — it is not a universal replacement for other application devices. Highly acidic wheel cleaners, acidic insect removers, and solvent-based tar removers do not belong in the foam dispenser, as the polypropylene seals and the stainless steel return spring will be damaged within a few applications at pH values below 4 or with aromatic solvents.\u003c\/p\u003e\n\n\u003cp\u003eReady-to-use interior cleaners like the classic Pol Star \"Po\" 1L or Top Star \"Ts\" should also not be refilled into the Foamer Bottle — these are already set to the correct concentration ex-works and would only take an unnecessary detour in the foam dispenser instead of coming directly from the spray bottle. The Foamer Bottle is a dilution and foaming tool, not a refilling container.\u003c\/p\u003e\n\n\u003cp\u003eFor exterior washing, the 150ml filling volume is simply too small and the spray radius too narrow — foaming an entire car body with the pump bottle takes half an hour and fatigues the hand. If you want to foam paint, you need a foam cannon for the pressure washer or at least a 1-liter pump spray bottle with a foam nozzle.\u003c\/p\u003e\n\n\u003cp\u003eFor precise application on interior surfaces → Foamer Bottle.

The second limitation comes from practice: The pump head has a limited stroke volume, and after 200 to 300 strokes with undiluted concentrate, the spring force decreases. Dilution is not optional here, but a technical prerequisite for a long lifespan.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-foamer-bottle-schaumspender-150ml_detail.jpg?v=1777826972\" alt=\"Koch-Chemie Foamer Bottle 150 ml with dilution scale 1:1 to 1:5 next to Koch-Chemie Pol Star concentrate in the Detailing1 Warehouse\" loading=\"lazy\" width=\"1200\"\u003e\n\n\u003ch3\u003eFor targeted interior detailing, not for the whole wash\u003c\/h3\u003e\n\u003cp\u003eThe Foamer Bottle is the right choice for anyone who regularly details interiors with concentrated cleaners — for their own vehicles, small detailing workshops, or professional detailers specializing in upholstery. If you already have COLOURLOCK Pol Star or all-purpose cleaner on your shelf, the foam dispenser is the most obvious application technique for it.\u003c\/p\u003e\n\n\u003cp\u003eThe bottle is less suitable if you only do a rough interior cleaning once or twice a year — in that case, the direct spray from the original bottle of a ready-to-use cleaner is sufficient, and you completely avoid the pump as a wear part. Even in purely commercial high-volume operations, where ten to fifteen interiors are detailed daily, investing in a compressed-air-based Tornador foam attachment is worthwhile — it produces more foam per second and relieves the hand during continuous operation.\u003c\/p\u003e\n\n\u003cp\u003eThe complete interior detailing set combines the Foamer Bottle with three components: a concentrate as the chemical dissolving component, a medium-hard \u003ca href=\"\/en\/collections\/buersten\"\u003eupholstery brush\u003c\/a\u003e for the mechanical dissolving component, and a microfiber cloth for absorption.

With ten interior sessions per year, the Foamer Bottle pays for itself in the first month. This is not a premium tool, but a consumable tool — and it works best in this category.\u003c\/p\u003e\n\n\u003cp\u003eOne trick the manufacturer doesn't mention: After each cleaning session, rinse the pump with clear water and let the bottle air dry open. These 60 seconds of care turn the €5.99 wear part into a tool that lasts easily two to three seasons — and this is where negative reviews that criticize the lack of care rather than the product itself fall short.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-foamer-bottle-schaumspender-150ml_workflow.jpg?v=1777826972\" alt=\"Application set with Koch-Chemie Foamer Bottle, Pol Star concentrate, upholstery brush, and microfiber cloth on a stainless steel workbench\" loading=\"lazy\" width=\"1200\"\u003e","brand":"Koch-Chemie","offers":[{"title":"150ml","offer_id":48867490890063,"sku":"D1-KCX-9998145","price":9.06,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/9998145__1715052916.png?v=1715112378","url":"https:\/\/detailing1.eu\/en\/products\/koch-chemie-foamer-bottle-schaumspender-150ml","provider":"Detailing1","version":"1.0","type":"link"}
