What does WD-40 stand for?

Published by Sirena Van Schaik at 1:09 am under Science, What?

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.
