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😁

Great snow foam! Produces thick, rich foam that clings well and lifts dirt effectively. pH neutral, so it’s safe on paint and coatings. Leaves the car looking clean and glossy—highly recommend!leakage

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.

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 👌.

Excellent prewash worth the money

There are so many car washes and Snow Foams out there, but I settled on this one after watching a YouTube video showing how long the foam lasts. Very happy with the performance both in the foam gun and in the bucket. Nice fragrance - a bit of a cherry smell. Very slippery feel when washing the car.

I like GSF particularly for contact washing because of its extremely high lubricity and neutral pH, however if you plan to use this in a foam cannon it tends to be extremely runny unless you add 2-3X’s more product than they recommend. If you need more foam dwell time then I’d recommend looking at other products, but if you’re already doing a foam pre-wash, then this is a perfect second foam product for contact washing.

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).

Hace muy buena espuma para un prelavado desprende gran cantidad me suciedad haciendo más fácil el lavado de contacto Muy recomendable no es barato pero vale la pena ya que rinde mucho

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