I ask this same question on another forum that I read. What is the best thing to use on the roof of a 2003 Jayco Kiwi Too, to clean and protect. The roof is not bad, we keep it in covered storage, I just want to keep it in good shape an take care of my toy.

It depends on what you roof is made of. Ours is TPF and all we do is wash it once or twice a year and check the seams for leakage. The TPF doesn't produce black run off either.

I use Dawn dish soap. The original blue stuff. I believe Spic and Span is also recommended. You don't want to use anything with petroleum or solvents nor stuff with citrus that will attack birds.
