ClenAir - Penetrate HD® frees stuck fan blades, blower shafts, pulleys, rusted nuts and bolts - any frozen, rusted, or seized metal part! It lubricates and protects metals with a dielectric strength to 50,000 volts. Penetrate HD is specially formulated with new low surface tension technology to seep into the smallest cracks, crevices, seams, or threads of rusted, seized, and corroded parts. It quickly dissolves the bonds of rust, corrosion, carbon deposits, gums, varnishes, and grease to free the metal parts. Penetrate HD displaces water and leaves a lubricating film to protect metal parts and further prevent rust and corrosion. The unique formula uses capillary action to penetrate into the smallest spaces.
