WD-40 Specialist® Rust Remover Soak – 1 Gallon
Safe, Acid-Free Rust Dissolver for Tools, Equipment & Metal Parts
Quickly and safely remove rust from metal surfaces with WD-40 Specialist® Rust Remover Soak—a powerful, non-acidic rust dissolver that restores rusty tools, auto parts, farm equipment, chrome, cast iron, and more to bare metal without the need for scraping, chipping, or scrubbing.
