The BrightCovers system is virtually maintenance-free. A heavy rain will naturally clean the top of the roof panels and system. If debris or markings remain after a heavy rain, the entire system can be cleaned with dish soap, lukewarm water, and a non-abrasive cloth rag. Windex or other chemical based solutions are not recommended as they may damage the panels over time. The aluminum components can be similarly cleaned with dish soap and water; a melamine sponge (household name: “Mr. Clean Magic Eraser”) can be used on any aluminum surface to remove dirt, grime, or otherwise should dish soap and water not suffice.
