Rust preventive oil, for use in removal of rust and corrosion from corroded iron surfaces, stainless steel, or any other metal surfaces. This uniquely formulated oil is excellent water displacing, a non-staining agent that effectively removes water from metal surfaces after machining operation or alkali cleaning and helps to prevent further oxidation of metal, also saving a large amount of money. This oil works by creating a protective layer around the interior surface of the metal which prevents contact of the corrosive substance with the metal.
