Good shampoo.

I was not impressed with the product. Minimal lubrication and low cleaning ability. Much cheaper car shampoos like Ucare, Arexons, and even Wurth with wax do a much better job!

Good shampoo without foam, with good lubrication and it does not affect waxes or sealants. However, it leaves marks and spots very easily before you even finish the whole car, so it requires quick rinsing and drying

It's not something amazing, just a simple shampoo. It's the myth that these products have created. These are low-quality products like these for technical use; the more professional ones might be better at a higher level. 3M is definitely not it

Very good shampoo with 9.5 ph/................. 100 to 150 ml in 7 liters of water for better results add 50ml Green star to prevent the creation of spider webs in washing professional products

Amazing product, quite affordable, since it accepts great dilution. Overall, Koch-Chemie products have not disappointed me so far.

I was expecting something better from this company. Really, their shampoo is not worth it and if you have tried enough like me, I find it very mediocre. It doesn't foam at all and its cleansing power is so-so. So far, I haven't found a better shampoo than bilt hamber.

Economical due to high dilution with very good cleaning results. When the car is very dirty, it helps that I also add about 30ml of the same company's GS and nothing is left.

I believe it is a good shampoo with good lubrication. I also add 50ml of Gs Geen Star from the same company for professional results.
