WD-40 is the trademark name of a penetrating oil and water-displacing spray – one of the popular things you’ll find in every home.
It was developed in 1953 by Norm Larsen, founder of the Rocket Chemical Company, in San Diego, California. WD-40, abbreviated from the phrase “Water Displacement, 40th formula,” it was originally designed to repel water and prevent corrosion, and later was found to have numerous household uses.
