If you want to create ultra-thick snow foam, a dedicated foam cannon soap will be required. They are specifically formulated to lift and dissolve dirt without having to touch the paintwork and are highly effective for use as a pre-wash solution.
The best foam cannon soap is the Chemical Guys Snow Foam Soap, which is a pH neutral formula that’s available in a honeydew or watermelon scent.
Although you could dilute a regular car wash soap, it wouldn’t produce the same foaming abilities as a dedicated foaming formula. Once the foam cannon soap is introduced to water pressure, it will be able to produce millions of thick suds.
