ASV® Penetroil is a fast acting industrial grade lubricant, rust penetrant and corrosion inhibitor. It forms a clear thin nondrying lubricating film that penetrates deep into the minutest crevices to displace trapped moisture and leaves behind a protective film to seal out further moisture and corrosion. Its unique low surface tension formula rapidly attacks rust to free seized or frozen components. It is non-conductive, nonstaining and offers complete protection to metal surfaces indoors as a medium term corrosion inhibitor for protection against corrosion and moisture penetration for up to 12 months under normal storage conditions. ASV® Penetroil does not contain any silicones, ozone depleting chemicals, CFC’s or harmful chlorinated solvents and is safe for use on around all metals, plastics, rubbers and other industrial finishes.
