Our SealGreen Rust Remover will remove iron stains from almost any surface. We recommend doing a test in an area where is not very visible before applying the product to the entire surface. The test will show if the product has any damaging effects on the surface.
Please note that it must be a rust stain from iron. Not all brown stains are rust.
The product is available in 8oz size that can be used for testing and removing rust in small areas.
