Every kind of aluminum cleaning spray is meant to be sprayed on and rinsed off, mainly because it`s for aluminum wheels. However, I don`t want to do any rinsing. In my engine bay I have aluminum parts that are bare aluminum, as well as anodized. For example, my intake pipe is bare aluminum, and I`d like a product to lightly polish and wipe away grime without the black mess associated with normal polishing and buffing. This is just for maintenance to prevent oxidation. For my anodized parts, I`m not sure what`s safe. I`m about to sent some parts out to be re-anodized after the finish was damaged by Meguiar`s Super Degreaser. I don`t want to go through that again. Any suggestions would be appreciated, thank you!
