Non-toxic Rust Remover Bath is a clean, safe, and easy solution to removing rust from iron and steel. A unique and chelating agent removes rust (iron dioxide) without posing any health, safety, or environmental issues. Contains no acids, no caustics, and is safe on skin. Soak the parts in a plastic container from 10 minutes to 24 hours depending upon the severity of the rust, type of metal, and liquid temperature. No scrubbing, dipping, brushing, or other agitation. De-rusted parts are available for immediate use after removing from liquid.
