Anyone out here have a tip for removing the black streaks that all campers seem to get after sitting for a while? I've tried: Magic Erasers Simple Green Soap Citrus cleaner

An RV tech told me that it is butyl caulk (or tape) that causes the black streaks.

I have a white truck that sits outside. After a while it will have black streaks on it. No butyl tape, caulking or rubber roof. It must be the dirt in the air that we breathe.
