Rust Penetrant

Maintenance Supplies

Penetrates and dissolves rust bonds to free corroded parts, while providing temporary corrosion protection to bare metal.

Rust penetrant is a thin, fast-acting lubricant formulated to penetrate rust and corrosion, breaking down the bond between oxidized metal layers. It is used to loosen rusted fasteners, hinges, and machinery before disassembly or repair. Many rust penetrants also provide temporary corrosion protection to exposed metal surfaces, reducing new rust formation.
