Diamond Performance Snow Foam is a pH neutral, wax bearing foam supplied in a 500ml bottle, diluted at around 200:1 using 1 to 2 caps of solution for every 500ml of water. It is designed as a pre-wash stage: foam it over a rinsed vehicle, leave it to dwell for about 5 minutes, then wash with a mitt and rinse with clean water. Used this way it helps loosen dirt before contact washing rather than replacing the wash itself. It suits owners running a foam lance or pressure washer foam attachment as part of a regular routine, and pairs well with a dedicated shampoo, a wash mitt and a two bucket method for the contact wash that follows.
