Penetrating Oil

Maintenance Supplies

Penetrates tight spaces and dissolves corrosion to loosen frozen or rusted fasteners and metal components.

Penetrating oil is a low-viscosity lubricant formulated to seep into tight spaces between metal surfaces and dissolve rust and corrosion. It is commonly used to free stuck bolts, rusted fasteners, and frozen hinges before removal or repair. Allowing time for penetration significantly improves the success of loosening corroded connections.
