Description
xOverview
WD-40 Specialist Rust Remover Soak is a dedicated rust-dissolving solution designed to tackle stubborn rust on metal parts and tools. This non-toxic, biodegradable soak dissolves rust and helps restore surfaces to bare metal without the need for aggressive scraping. It is formulated to be gentler on surrounding components like paint, gaskets, trim, and seals, while delivering serious rust-fighting action.
Because it avoids acids and caustic ingredients, it is suitable for use on a variety of metals with reduced risk of collateral damage and 50-state VOC compliance, with NSF Category P1 as a mark of safety and compliance in professional settings.
How it works and how to use
Light rust can be tackled in a matter of hours, while heavier deposits may require overnight immersion. Submerge eligible parts in the solution until you see a visible change, then rinse and dry thoroughly. Do not use on parts that have blueing, browning, or protective oxide paints, as those coatings would be removed by the soak.
- Light rust: 1–3 hours
- Heavy rust: overnight
- Submerge metal parts, then rinse, dry, and inspect
- Avoid coatings that are protective oxide or browning
