In a bucket with water and by dipping the sponge, it produces foam properly. Not suitable for pressure washers. It probably needs a specific dosage which is not indicated. However, it is very good for traditional cleaning.

After many washes with Koch-Chemie's Gsf, I bought this to try it as a pre-wash.... So I applied it with the pressure washer, but whether I applied it or not, there was no difference... I wonder how you claim that it cleans.... It's good as a shampoo, but not for that much money. And I am a fan of this particular company....

I use it both by hand and with a pressure washer/foam cannon. It creates a good foam both by hand and with the foam cannon and cleans well, although the foam doesn't last long (it disappears). It smells very nice, making the washing process pleasant. I only give it 3 stars mainly because I find it expensive. Especially with the foam cannon and following the recommended quantity instructions, it lasts for 5, maybe 6 heavy washes, so considering its price, it costs 2 euros per wash. Expensive! If we add other materials for wheels/interior/tires or whatever each person uses, the washing process will be as good as a professional's.

Awesome material, I used it with a pressure washer foam cannon and rinsed it with water. It cleans well and leaves a nice shine on the plastic parts of the machine. It's a bit expensive, but it's worth it because it protects the plastic parts from getting dull, which would cost a lot more to fix

Wonderful shampoo, cleans everything with a very rich foam and an amazing scent. I didn't expect anything less from Chemical Guys

Excellent product with a lid that makes a very nice lather and, in combination with a good sponge, makes washing very gentle
