WD-40 is an American brand and the trademark of a penetrating oil manufactured by the WD-40 Company based in San Diego, California. The formula for WD-40 was invented for the Rocket Chemical Company as early as 1953 before it evolved into the WD-40 Company. WD-40 became available as a commercial product in 1961. It acts as a lubricant, rust preventative, penetrant and moisture displacer. There are specialized products that perform better than WD-40 in each of these uses, but WD-40’s flexibility has given it fame as a jack of all trades.
It is a successful product to this day, with steady growth in Net Income from $27 million in 2008 to $70.2 million in 2021. In 2014, it was inducted into the International Air & Space Hall of Fame at the San Diego Air & Space Museum.
