EPDM roof care.
Hello. Can someone tell me what is the best safest way to wash and care for my EPDM tt roof? I want to wash it, and maybe put a mild protectant every other year. I have heard everything from spic & span, laundry detergent, vinegar, to citrus/no-citrus cleaners. Someone said Simple green is a safe cleaner?? Also, what is a good Cleaner/protecting wax I can apply on my "fiberglass" gelcoat sides?
Thank you in advance.
