WD-40, remember the time when you first heard this alphanumeric name, thinking of it as some kind of ultimate weapon, one uses when the other fails. The WD stands for “Water Displacement” and the 40 is the number of attempts the manufacturer made to perfect the solution. This shows that success doesn’t come in a single shot, one has to fail numerous times to hit perfection.

Who were the first users?

Convair, an aerospace contractor was the first to use WD-40, which was not in aerosol cans as we see them today. It used to come in tin cans but as a greasy solvent. They used it on their Atlas Missile outer body cover to protect it from rust and corrosion, it worked so well that some workers took some WD-40 to use in their homes.

Rocket Chemical Company founder Norm Larsen wanted the product to reach homes rather than restrict it to industrial use. He gave WD-40 a new suit, the one that we see now. The product reached store shelves in San Diego in 1958. The company was renamed after its only product WD-40 in 1969.

It has become a household name and is used in the consumer as well as industrial markets.
