KOCHCHEMIE Gentle Snow Foam - pH Neutral Pre-Cleaning; Works With Foam Cannons & Sprayers; Manual Washing Shampoo; Safe on Existing Wax & Sealed Surfaces; Unique Cherry Fragrance (1 Liter)

Koch Chemie GSF is easily one of the best snow foams I’ve used. It produces a rich, thick layer of foam that clings to the paint and helps loosen dirt and road grime before I even touch the car. The foam consistency is just right — not too watery, not too thick — which makes rinsing super easy.What I love most is that it’s pH-neutral, so it’s safe for waxes, sealants, and ceramic coatings. It’s perfect for weekly maintenance washes, and it leaves the paint looking fresh and glossy after every rinse.The scent is light and pleasant, which makes the wash process more enjoyable, and I appreciate that a little product goes a long way — it’s very economical when diluted correctly.If you’re looking for a high-quality, coating-safe pre-wash foam that delivers consistent results, GSF is a must-have in your detailing arsenal.

Best car shampoo out there great foam for power wash or just to clean regulary. I have hard water and after using this there is no spots left unlike others I have used in the past. I have used many and this is by far my favorite

Excellent foaming properties from a foam cannon. Left the car clean and smelling real good.

Soap was nice and thick. And car looked like I waxed it. Highly recommend this product. It is a bit pricey but well worth it.

This is a perfect ph balanced formula used for a “pre-soak” I foamed on let sit and 75% of dirt did cone off with a rinse. I applied again and used as my once a month hand wash on a black car. Follow dilution ratio and I definitely recommend using a foam cannon for application. Great product! Residue removal:Let sit for a few minutes and rinse off 75% of dirt

A good product, good lasting foaming action, nice smell (non-offensive)

Seriously Great shampoo. Smells so so so good and works better than any other products on the market. Don't fall for advertising from competitors, this stuff wins every time hands down

Hooking this Koch-Chemie Gentle Snow Foam into my pressure-washer cannon was the easiest win I’ve had in a while. Two ounces in the bottle, topped with warm water, and the lance laid down a dense white blanket that clung to my Subaru’s paint for a solid five minutes—even on the vertical doors. While it dwelt I could see road film softening, so most of the grime slid off with a low-pressure rinse before I ever touched a wash mitt. The pH-neutral formula left my sealant beading just as strongly as before, and the glossy finish actually looked a shade brighter once the car dried.The cherry fragrance is surprisingly pleasant for a detailing product, though it can linger in the driveway for an hour on still days. Not a deal-breaker, just something to know if you’re scent-sensitive. After three washes I’ve used about a quarter of the one-liter bottle, so the cost per wash works out cheaper than the big-box soaps that never foam this well. If your goal is maximum lubrication and zero risk to existing wax or ceramic, this is the bottle to grab.
