I'm sure Terra Wash would work great for cleaning the canopies, I have not used it for this. However, when I do gas station canopies, or other things that are glossy metal, some plastics, glossy painted surfaces, etc, I rinse after cleaning with a "clear coat sealer and wax" I buy from an automatic car wash supplier. I use it as an up-sell item, and it's cheap. It leaves a good shine, and has antistatic qualities that keep some stuff off for a little longer. I just put my Bleach Wash right in with it.

I don not have high volume DI at the moment, just a cart that runs off a garden hose with the little pencil jets. I would do a DI rinse if I had the ability, and I should have by June.
