Mud Away is a complex blend of acids designed to remove red mud, tire tracks, and rust stains from concrete slabs, blocks and brick surfaces. While Mud Away is effective in most cases, for the most stubborn rust stains see Rust Pro Rust Stain Remover.
Always test a small area on the surface to be treated. Use an all plastic pump up sprayer to apply Mud Away. For difficult to remove mud and rust stains, apply full strength to the surface to be treated. Work in 3 ft. by 5 ft. sections to completely cover the surface to be treated, and use a plastic bristle brush or broom to work Mud Away into crevices, cracks and design work. After application, let the chemistry work for you by allowing a minimum of 10 minutes of contact. Stubborn or extremely old and set stains may take up to 30 minutes. Use a high pressure sprayer to remove the treatment, mud, rust and most stains from concrete.
