Rust Remover Plus™ (5 Gallons)
Rust Remover Plus™ is a perfect choice for removing tough rust stains from concrete and exposed aggregate surfaces. Just spray it onto dry concrete with a pump up garden or chemical sprayer and watch the rust and oil stains disappear.
It's the only product I've used that truly removes the rustThis product really does the job, although it does need more than one application for rust spots that have been there for a while. We used it at a 1 to 1 concentration and spayed the entire area as if you only apply it to the rust spots the area will become whiter than surrounding areas.
