It was developed in 1953 by Dr. Norm Larsen,[1] founder of the Rocket Chemical Company, in San Diego, California. WD-40, abbreviated from the phrase "Water Displacement, 40th formula,"[2] was originally designed to repel water and prevent corrosion,[3] and later was found to have numerous household uses.
Larsen was attempting to create a formula to prevent corrosion in nuclear missiles, by displacing the standing water that causes it. He claims he arrived at a successful formula on his 40th attempt.[3] WD-40 is primarily composed of various hydrocarbons.
WD-40 was first used by Convair to protect the outer skin and, more importantly, the paper-thin "balloon tanks" of the Atlas missile from rust and corrosion.[3][4] These stainless steel fuel tanks were so thin that, when empty, they had to be kept inflated with nitrogen gas to prevent their collapse.

WD-40 first became commercially available on store shelves in San Diego, California in 1958.[3]
