Washing a car that has been coated with something???

I don't use water on mine at all. I had a paint protection treatment on when new and use Showroom Shine to clean. Spray on, wipe dirt off, buff with a clean cloth. No swirls or scratches, brilliant shine. Fantastic stuff.

Car gets dusty, but no rainwater marks even though it beads.

I learned in the same school. Washing-up liquid is a bad choice though, as it contains salt - the last thing you want to be sloshing around exposed metal. Even cheap car shampoo is better.

That not the problem with washing up liquid. Get rid of the wax that protects the body work. But it does sometimes have a purpose to strip off old wax before re waxing

I use a drop of all purpose cleaner in some warm water to strip the wax and sealer off my car when its due a reseal and wax, the only thing to get the sealer stripped IMHO tried fairy up liquid but the sealer tends to repel it and it leaves a residue thickly over the surface. AP doesn't foam up so much and strips it back nicely to a fresh surface.


Foam gun, rinse down, clay, polish, sealer, wax job done for the next 6-8 months.

Well, a bit of both actually. The liquid contains about 5% salt as a thickening agent and is an effective degreaser. The detergent removes any wax/grease from any exposed metal, and the ions in the salt create a nice corrosive cell.
