Most active snow foams affect coatings or protective layers (waxes) either by being strongly caustic or leaving a thin layer that can destroy their protective and self-cleaning properties.  

Q²M Foam is totally safe for your coating, but also for uncoated cars or surfaces like polished alloy rims or exterior trims. 

A thick foam is one of the major benefits of high quality snow foams. Gyeon Q²M Foam builds up a very thick and deep foam, sticking to dirty areas of the paint and dissolving dirt and grime. The foam should be washed away by a pressure washer before it starts to dry.

Gyeon Q²M Foam is very effective, it dilutes even 1:15, giving great value for money. To keep the foam fully effective, the minimum dilution is 1:15, but in the case of very dirty vehicles or uncoated ones, it is advisable to use in a proportion of 1:5.
