WD-40 Origin: Who Invented It And What The Name Means
Word Wizard
Beginning in 1953 a small company in San Diego attempted to come up with a chemical mixture that would effectively protect metal parts from rust.
This small company made up of only 3 men was called Rocket Chemical Company and it took these chemists quite a few tries to come up with the right formula.
It wasn’t until the 40th try that the WD-40 that we know today was born.
The “WD” portion of the name stands for Water Displacement and the “40” is, of course, the 40th attempt at getting the mix right.
