WD-40 is a well-known brand primarily associated with its multi-purpose lubricating and cleaning product. It was developed in 1953 by the Rocket Chemical Company, now known as WD-40 Company, in San Diego, California. The name WD-40 stands for “Water Displacement, 40th formula,” referring to the fact that it was the 40th attempt to perfect a water-displacement formula.
Originally, WD-40 was used by Convair to prevent rust and protect missile components. Soon employees discovered the product's versatility and began taking it home for personal use. In 1958, WD-40 was first introduced to the consumer market in spray cans.
