What does WD-40 stand for?
I’m not sure about you but I have several cans of WD-40, it is amazing stuff and I have used it for many things; although it has mostly been used with my key hole, which has the misfortune of being completely exposed by the elements and a strong blowing wind almost daily.
For those who aren’t sure, WD-40 is a spray oil that is used as a lubricant, a cleaner and for anti-corrosion. It was invented in 1953 and became available for households across the country in 1958. The inventor of WD-40 was Norm Larson (1923-1970).
WD-40, which is also the trademarked name, stands for water displacement, which is a way to prevent corrosion. The 40 stands simply for the 40th solution (or attempt). This means Norm Larson created 39 other failures before success.
