I used Blue flat 3m no scratch scrub pads that I purchased at Home Depot. I wet the RV and then scrubbed with bar keepers friend. Rinse well.Dried with old towels and applied Protect All with caranuba wax. No wax chalky residue noted. Just a clean shine. The protect all polishes.waxes.treats.Protects. It even has UV blocker and is good for multiple surfaces. I comes with a 100% satisfaction guarantee. 98% of the black marks came out. My arm is just a little bit sore. Worth the effort.
