The pre-wash stage is the most vital stage of washing your vehicle before you make any form of contact on your paintwork with a wash mitt or sponge. It is extremely important that you use a good citrus based pre wash and PH neutral snowfoam like ours to loosen up any dirt and grime on your vehicles paintwork. Once this stage is complete you can start the wash stage with our PH neutral Jelly Bean Shampoo+ or Ultimate Wash And Wax in a bucket to effectively clean your vehicles exterior without removing any sealants or waxes.
