Make it white once more
I was on my roof today, TPO membrane. Scrubbed it hard with Simple Green. It took most of the black off the joints, but once I rinsed it off there is a nice white area where the antenna covers it, the rest is dingy gray.
What can I use to bring the white back? Even the lap seams have gray patches where they didn't come white. I want to get it as clean as I can before wiping it all down with UV protectant.
