What is WD40 and what can it be used for?


The story that WD40 (Water Displacement 40) is basically fish oil is a myth.

It is actually:

Solvent naptha petroleum, medium aliphatic 60%

petroleum base oil as paraffinic distillate, heavy, silvent dewaxed (severe) 15% to 25%

corrosion inhibitor unregulated 1% to 10%

wetting agent unregulated 1% to 10%

fragrence unregulated 0% to 1%

carbon diaxide 2% to 3%

WD-40 was created in 1953 by three technicians at the San  Diego Rocket Chemical Company as a a rust preventative solvent and degreaser to protect missile  parts..

They were successful  with the fortieth formulation, thus WD-40.  The Convair Company bought it in bulk to protect their atlas missile parts. Ken  East (one of the original founders) says there is nothing in WD-40 that  would hurt you.

For a long list of what WD can be used for, the makers have agreed:
