Before you start, check that the bodywork and wheels are cool to the touch and out of direct sunlight.
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.
Spray Polar Blast onto the vehicle, starting at the bottom, ensuring all exterior surfaces are covered, including glass and wheels.
Leave Polar Blast time to dwell and loosen dirt for up to 10 minutes, although do not allow it dry on.
