EPDM Roof Cleaner Suggestions

[chuckbear]

We've been parked under some wonderful old oak trees for a few months and man what a mess. About 6 months ago we recoated the rubber roof on our Fleetwood Bound with EPDM RV Rubber Roof coating. It looked great until now. So we are looking for some first hand suggestions on what others used on a like roof to clean the tree sap and other stuff the trees have dropped. I have already tried various soap and water types like Joy and our regular car wash. Nothing has touched it so far. Any suggestions would be appreciated. Chuck

Tree sap. I have not had anything that worked well. I tried Turtelwax tar remover with limited success. But I don't recommend it. It's really not good for the roof.
Cleaning I found DICOR roof cleaner to work the best for me. Good luck.

Another coat of treatment.
