How often do you polish the roof?
Our van is parked beneath several silver birch trees and is also on the edge of a forest. This year particularly, we weren't able to cover before leaf fall because of the persistent inclement weather so, at the time of putting it to bed, we had to wash a lot of green off it.
No problem however and no leaf stains, perhaps because we cut and polish our roof at least once a year?
Just a thought
