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.

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😁

I’ve been using Koch Chemie Gentle Snow Foam for a little while now, and it’s become one of my go to soaps for my mobile detailing business. The foam is thick, spreads evenly, and gives me plenty of working time. It also has a really clean smell to it. What I like most is how gentle it is while still lifting a lot of dirt, especially on cars that just need a maintenance wash. It rinses off easily and doesn’t leave any film or streaks behind. I’ve been using the 1 liter bottle to test it out, but this product won me over I’ll be grabbing the 5 liter container next time. If you’re a detailer or just wash your own car regularly, this is a solid choice.

Excellent quality auto shampoo. It works excellent with a foam cannon. Produces alot if foam and smells very good. Highly recommend Kochchemie they have excellent products for all auto detailing needs! Two 👍🏾👍🏾 up.

Another great product from Kochchemie. I use this through my MJC foam cannon and it coats with a nice thick foam that smells great. I will be buying again.

It's a great soap and smell amazing. I use 1-2oz os soap (rest water) on a 24oz foam cannon and it produces amazing suds. Leaves a smooth velvet paint finish 👌.

i am a professional detailer. yes it is a great product. but for the price it really is no different than meguires gold class or adam’s car shampoo. my go to is suds lab. there really is nothing special about the product. it foams well and slides well but for $30-$40 it is not worth it. i didnt notice anything special about it. but if you have the money to throw at the “hype” go for it. it is a great product but there are cheaper alternatives that work just as well. i use lots of koch chemie products but gsf, nothing very special.

This snow foam is amazing — produces thick, rich foam that clings well and breaks down dirt effortlessly. It’s super gentle on paint, wax, and ceramic coatings since it’s pH neutral. The scent is clean and subtle, and it rinses off easily without residue. Perfect for pre-wash or maintenance washes, and it works great in a foam cannon or pump sprayer. Leaves the car looking spotless and glossy every time. Definitely worth it for anyone serious about car care!

I have been a detailer for over 10 years and used other soaps up until this year. My soap I used before literally doubled in price so I looked into this soap and was shocked. Smells amazing, works great in a bucket and foam cannon as well as a foam hand sprayer. Dwells great and cleans better than any soap I've used.

This is a very high quality snow foam. It produces thick suds in my foam cannon and does a great job of getting the large majority of dirt off my vehicle prior to the was stage. You can see it binding directly to the dirt and washing it away. The solution is fairly concentrated so you can get many washes out of this 1L bottle as well (I dilute 1:50 as recommended).

30@40 ml pour une bonne mousse

Excellent scent, excellent suds, provides great lubrication for washing.

I wanted a stronger soap for the winter months so that less time was spent on contact washing. This didn’t accomplish that. While cleaning power was good - contact wash is still 100% necessary. Used in an MJCC foam cannon at recommended dilution of ~1oz:1L , the foam was as if you poured milk on the car. Was super thin and ran off quickly. I needed to up the ratio to 5oz:1l to get a thicker foam that would both coat and dwell a bit longer. At that ratio this becomes extremely uneconomical. So while the cleaning and slickness is on par, if you prefer a thicker foam from your cannon - this one’s likely not going to be for you. The soap itself has the viscosity of Meguires Gold Class and the performance + dilution requirements of P&S Pearl (which would be far cheaper). At the price and what I’m looking for - it’s just not for me
