A complex blend of acids designed to remove red mud, tire tracks, and rust stains from concrete slabs, blocks, and brick surfaces.

Usage Directions

Always test a small area on the surface intended to be treated. Use an all-plastic pump-up sprayer to apply Raptor Rust Buster. For difficult-to-remove rust stains, apply the product at full strength to the surface to be treated. Work in 3 ft. by 5 ft. sections to completely cover the surface, and use a plastic bristle brush or broom to work Raptor Rust Buster into cracks and other crevices. After the application, allow a minimum of 10 minutes of contact for the chemistry to work. Tough or extremely old and set stains may take up to 30 minutes. Use a high-pressure sprayer to remove the treatment, rust, mud, and most stains from concrete.

NOTE: Do not mix this product with any other product, nor use it on any other surface than listed on this label. Do not allow it to dry on surfaces. Always rinse thoroughly. Avoid contact with skin and eyes. Do not allow it to freeze. Do not store at temperatures above 120°F. Keep out of the reach of children. For industrial use only.
