This is our first year with the TT and I just cleaned the roof and plan to seal. I used a natural cleaner called Miracle II. We've used it for years for cleaning everything. I even brush my teeth with it. You can dilute it to any strength you need. Straight out of the bottle is the best product I've used to clean motor oil off my hands. No chemicals so it's friendly to me and environment. I found that it worked much better than the Protect All Rubber Roof Cleaner that I bought. That stuff requires rubber gloves and you have to mop up the residue because if you let it spill over the edge it will stain the finish on the sides. With the Miracle II I just scrubbed it lightly with a brush or sponge and then rinsed it off.
I also bought the Protect All Rubber Roof Treatment, but read that it only lasts 3 to 6 months. The Dicor coating says it lasts longer. But they have 2 products. One that cleans and primes and the other that coats. My question is that since I already have a clean roof is it necessary to use their cleaner and primer too or can I just apply the coating?
