Have you ever wonder what the WD in WD-40 stands for?

The name was lifted right out chemist Norm Larsen‘s laboratory notebook.

Way back in 1953, he was trying to concoct an anti-corrosion formula, which worked on the basic principle of displacing water.

On his 40th try, Larsen finally got it right.  Hence the name WD-40.

It literally means Water Displacer, 40th try.
