The WD-40 Company is a true American success story. Founded in 1953, the company started out as a small operation selling a single product: WD-40, a rust-prevention solvent. Today, WD-40 is a household name, and the company has expanded its product line to include a wide range of cleaners, lubricants, and maintenance products. Throughout its history, the WD-40 Company has been defined by innovation. In the 1960s, the company was the first to introduce aerosolized aerosol packaging, which made it possible to spray WD-40 in any direction, even upside down.
