I’ve tried various brands of snow foam and other car cleaning products over the years. The majority have been average and appear to be gimmicky. However, the products VP detailing sell, are the dogs. I am very happy and I won’t be getting my stuff from anywhere else in the future.
Anything with iron content instantly turns red! A light misting over the wheel arches and doors revealed that the brake dust had gotten everywhere. This is definitely one of the better products out there! I'm glad I switched to using this, but if you regularly wash your car, then I recommend going straight to the 5L stuff because you'll enjoy going crazy with this stuff!
