Now that you've removed the heavier dirt and grit from the car, it's time for a 2 bucket hand wash with Auto Body Gel. We use this wash as its a more pure wash and won't leave any extra elements on the paint after its use. Grab your Wash and Rinse buckets with Great Barrier Thingy's in them, and your favourite wash tool (we love The Wash Pillow). Put 1 capful of the Auto Body Gel wash into the Wash bucket with approx 10-12L of water, and froth it up with your pressure washer or hose.
Wash sections of the vehicle at a time, starting at the top, and working your way down to the dirter lower sections last. After each section (quarter of a roof, bonnet etc), dip your wash tool into the Rinse bucket to get any dirt and grit out of it, then go back into your clean wash suds bucket and continue around the rest of the car, doing small sections at a time.
