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😁

Wow! That's all I could say the first time I used this stuff. I used my Ryobi pressure washer (not a very high pressure unit) and the foam that my foam cannon produced was incredibly thick and really shaving cream like. The cleaning power is excellent with the long cling time. I wasn't really sure what people were referring to as the "secondary foam" on this soap until I used it- During the rinse process, a secondary suds or foam is activated when the water hits the soap residue. It takes a bit of extra rinse time but I assume that increases the cleaning power. I'll have to fully dial in my ratios before I can assess the value for money on this stuff but it seems like a little goes a long way.

One of my favorite foams as a detailing business owner. It smells incredible, is super slick, and creates a wonderful thick foam. This is the favorite of many for a reason. The PH neutral soap allows for use on coated cars as well. I've gone through many bottles of this snow foam and always keep coming back!

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

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.

Works great on mine ans wife's ceramic coated cars best results when blown dry

So thrilled my dealership recommended Koch Chemie Gsf for my high gloss finish. Gsf, foam gun and a super soft cloth has made my life so much easier. I have people stop me to compliment how Wow my vehicle looks.

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

Genera una espuma densa, bastante densa en un foam canon. Si bien se recomienda de dilución en algunos foros 100ml por cada 900 de agua. Lo cierto es que con 50ml es mas que suficiente para generar una espuma muy densa. Ahora bien, por cuanto hace a la limpieza que por si solo debe hacer el prewash, ahí si no es el mejor producto, pues no desprende la mugre o suciedad del coche por sí solo, en ocasiones pareciera que no se desprende en lo más mínimo.

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