Stained roof

[4Daughters]

The previous weekend when we camped we were hit with several storms Saturday. It blew leaves onto the roof of the camper. I cleaned them off the next morning, but now I have stains from the leaves. I tried two different roof cleaners with no noticeable results. Any recommendations? Below is what I tried. Thanks!

I use Rubber Roof Cleaner by ProtectAll. The conditioner is in a separate bottle. It removed stains from my roof that had been there for years after cleaning with other products. And it is no rinse, so it doesn't leave streaks down the side of your RV. Might be worth a shot. I only had to use a stiff brush on a few stubborn stains, the rest came off easily with a sponge.
