Mega Foam is a new generation premium quality pH balanced snow foam which can be applied using a pressure washer or foam gun as a pre-wash stage. It covers the vehicle in a rich blanket of foam that clings to paintwork to gently loosen dirt and heavy soiling prior to shampooing. Mega Foam is a non-caustic formulation made with biodegradable compounds. It is extraordinarily effective on soil and grime, yet harmless to paintwork. Mega Foam reduces the risk of scratches and swirl marks caused by a sponge, wash mitt or brush over heavy contamination. It can be used instead of a shampoo as long as the vehicle isn’t heavily soiled, just be sure to rinse the vehicle with water first to remove the top layer of dirt.
