The fun part
Squeeze the trigger of your pressure washer till the foam starts coming out.
Adjust the Cannon’s blue end nozzle to find your desired foam arc. We like it around half to two thirds the way between full fan and powerful jet.
Keep the Cannon about a metre away from the cars surface to cover it in a lovely, thick foam. Starting on the lower sections and rear of the car, working your way around the car, from the bottom to the top, allowing the foam a longer dwell time on the dirtier lower areas. Let the foam sit and do its work for 4 to 5 minutes, gently dissolving the grit and dirt from the surface.
