Active Foam - Phosphate and NTA Free, Paintwork Protective, Unique Foam Formulation, Long Lasting Sandalwood Aroma (5 Liters)

Koch Chemie Active Foam has completely changed my car wash routine. The foam it produces is thick, rich, and clings to the paint extremely well. It works great in a foam cannon, creating a blanket of suds that loosens dirt and grime before I even touch the car with a wash mitt. I’ve noticed that it rinses cleanly and leaves the surface looking fresh without any residue. It’s safe on waxes, sealants, and ceramic coatings. The scent is also really pleasant, which makes using it even more enjoyable. Whether I’m doing a quick maintenance wash or a full detail, Active Foam is my go-to for the pre-wash step. It’s high quality, efficient, and absolutely worth having in your detailing arsenal.

I can’t believe how clean my car was after use. I used a foam cannon and let it dwell for ten minutes. I then washed by hand with my Meguiars car wash suds. It had never come this clean with just this ordinary car wash. The windshield, windows, paint and all were squeaky clean and there is an awesome aroma of sandalwood. Leave it to the Germans. I followed this with CARPRO HydrO2 Lite sealant. Amazing.

This soap makes a great prewash and smells amazing. Works well in a foam cannon and takes a lot of dirt off before the contact wash.

Excellent auto shampoo for the stubborn contamination on paint work. Paint will still need to be clayed to remove the deep contaminats from the paint but this is the first recommend step. Smell great as well. Produces very excellent foam as well. Two 👍🏾👍🏾 up.

Buy it now. This has got to be the best product on the market. Very foamy, leaves a great smell and worth the money.

I'm surprised that I have not written a review for this yet. I am amazed at how great this product is for washing cars! When I finally decided to get a power washer, I was on the hunt for the perfect foaming soap. I read reviews and settled on this. After foaming the car and leaving it on for about five minutes, a good pressure was just took away all the dirt and grime from my car. Tonight, I had the crazy idea of using this in my bathroom. I would rather clean my car than my shower, just because it's so much easier to be outside with a pressure washer. But I remembered that I had this manual pump sprayer bottle. I then saw that it had a foaming nozzle! What a treat! So, I mixed the soap with water, pumped the sprayer bottle and went to work. Warning: Make sure to turn on your exhaust fan when doing this! The foam coated every inch of my shower and I saw immediately the discoloration from the suds that were dripping down. Eww, I know! But yay, too, because it was working!!! My shower looks brand new!!!

I’m a big fan of Koch Chemie products and Active Foam is not widely talked about in the car detailing world so I decided to check it out. It’s basically a combination of their GSF (gentle snow foam) and GS (green star APC). I can’t tell exactly how much GS is in it but from what I can tell it’s something like 10-30ml per liter used in a 1 liter foam cannon but because this is concentrated, my guess would be 25% GS? I tried this soap at a 10:1 mixture in my foam cannon and while it did produce plenty of suds it did almost nothing to knock down a thin layer of road film on the lower panels. I finally tried it at 4:1 and it did loosen up most of the road film but it still needed help from the pressure washer to help knock everything down. At that rate I’m better off doing a citrus pre-soak and foaming with a ph neutral soap but for now I’ll just keep using AF unless the vehicle is heavily soiled. Even at 4:1 I calculated that I would still get around 30 washes so this 5L container should last me up to a year? At 4:1 the foam was super thick and clings to the panel nicely so I really liked that. Just know that it can weaken your protection if you use waxes, but I top mine off every few washes so that’s not a problem for me. One thing I didn’t like about it is the scent. I normally prefer scented car care products but this soap smells like Obsession for Men which I never cared for. It’s a sandalwood spicy scent which will leave your garage smelling like cologne which I don’t typically associate with waxes and soaps. I much prefer the cherry scent of the regular GSF. I haven’t tried AF in a contact wash or tested the lubrication since I use other soaps for that. Overall I like it but was expecting it to be stronger at the 10:1 ratio.

I found the scent a bit strong (especially if you dont rinse it well from undercarriage), but my wife really liked it. Nice shaving cream foam from mjcc cannon with 1000 psi pressure washer. Not great at getting tough grime off lower panels but not fair to expect that of a neutral foam

Amazing product, cleans really well and perfect for your snow cannon. The neighbours always say it smells amazing when I’m using this

very good. Fast delivery. It is what I want.

Awesome! Good for pre-wash method, smell good too.highly recommended...

great foaming car wash. price is a little high i might try some other brands to compare but koch is pretty solid and doing a great job for my pre wash

As a pre-wash foam to cut through Canadian salt accumulation I doubt anything is better, thick suds and a glorious scent this stuffs a banger!
