Liquid Tool Penetrating Oil
920 LIQUID TOOL combines active solvents with highly refined oil to provide the most useful "tool" in your tool box. 920 LIQUID TOOL penetrates frozen and rusted parts, cleaning, and lubricating all metal surfaces as it "unfreezes". It removes moisture from surfaces, leaving an oily film that protects against the intrusion of further moisture, thereby preventing rust and corrosion. 920 LIQUID TOOL leaves a residual film on all parts, which increases the natural lubricity and reduces friction.
