Parked the RV under a Walnut tree. First time at the free spot in the summer. Neglected to notice walnuts dropping on, rotting on, staining my roof. Looks like it may be hard to remove stains. Any ideas on a good product? Aluminum roof.
The same thing happened to my MH in Tenn last week. All the slide toppers are now stained with nice little brown blots. Tried to scrub them out with no luck.
Why would it matter? I have lots of stains on my roof too but they don't cause and problems. I wash and rinse the roof a couple of times a year, that's it.
