WD-40 stands for Water Displacement, 40th formula. The name comes from the lab book used by the chemist who developed the product. The original secret formula for WD-40 was perfected on the 40th try by the Rocket Chemical Company in 1953. The product was initially developed as a rust-prevention solvent and degreaser for use in the aerospace industry. Today, WD-40 is a household name and is used in numerous consumer and industrial markets such as automotive, manufacturing, sporting goods, aviation, hardware and home improvement, construction, and farming. The product is a water displacement spray containing a mixed blend of lubricants and anti-corrosion properties. Its job is to displace water, though it doubles up as a solvent and degreaser in one.
