POLAR BLAST is a snow foam that can be applied through a pressure washer or foam gun. It covers the vehicle in a rich blanket of foam that clings to paintwork to gently loosen dirt and heavy soiling. Using a snow foam as a pre-wash can reduce the risk of scratches and swirls as it gently loosens dirt which is then rinsed off prior to shampooing. POLAR BLAST is pH neutral so it will not remove any polish or wax you have previously applied. How to use this product 1. Before you start, check that the bodywork and wheels are cool to the touch and out of direct sunlight. 2.Polar Blast can be used at various dilutions depending on the density of foam desired. A good starting point is 100ml product to 500ml water in your foaming bottle. Adjust foam gun settings as required to increase or reduce foam. 3. Spray POLAR BLAST onto the vehicle, starting at the bottom, ensuring all exterior surfaces are covered, including glass and wheels. 4. Leave POLAR BLAST time to dwell and loosen dirt for up to 10 minutes, although do not allow it dry on. 5. Finally, rinse thoroughly from the bottom up.
