Simple Green Cleaner for Your Roof

I've used it over 10 years on two campers. Works well no roof issues.

Twice a year. I dilute it about 10/1 with water, scrub and rinse. Great results.

According to Simple Green, it is the best thing ever to use on your rubber roof. It is not citrus based as some folks think.

Use it al the time along with some bleach--works just fine.
