Use with a snow foam lance. Snow Foam Wash ‘N’ Wax is specifically formulated to create a dense foam that clings to paintwork, effortlessly breaking down and lifting dirt and contaminants from the surface. As a high-performance detergent, it powerfully removes all traces of traffic film, dirt, and grease leaving a spotless, streak-free, shiny finish. Use regularly to maintain car paintwork. Snow foam in its simplest form is a high-foaming detergent, the reason for the extra foam is that it allows the active cleaning component to stay in contact with the surface giving a longer dwell time, which leads to higher cleaning rates from the detergent.
