KOCHCHEMIEGentle 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.

Legit the best pre wash foam to use with a foam cannon. It simply doesn't get better than the quality, smell, and effectiveness of the kosh chemie stuff. As soon as you spray it on, it sticks to the paint and doesn't all run off. It then removes like 60> of the dirt before you even touch the car! I use this as my pre was every time followed by the ceramic effect shampoo, and protector wax. Another thing is the bottle lasts for AES. You dilute it a lot so the 1L last for like 60-70 washes. Would never get any other brand except these guys😁

Foams up real good and smells even better nice cherry scent couldn’t be more happy

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.

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.

Got this one since my car has ceramic coating but for some reason it seems to stick to it, it makes it hard to come off, not sure why!

Exelente

good stuff that does what it says - easy to use…smells good & effectively cleans well
