Metal Rescue Rust Remover Bath is your clean, safe and easy solution to removing rust from iron and steel. Metal Rescue Rust Remover Bath will take rust off the most heavily corroded metal parts, yet it is safe enough that you can put your bare hands into it. Metal Rescue is most effective when used as a bath or soak, simply immerse metal part in a plastic container for 5 minutes to 48 hours depending on the severity of the rust. Easy to use, virtually no labor involved (no scrubbing, dipping, brushing or other agitation). Just soak, check, and dry. No acids, no caustics, no health risks, non-toxic and safe on skin. Metal Rescue does not remove properties of the metal, does not etch the metal like an acid, leaves metal surface intact and less susceptible to return/flash rusting.
