What is The Main Ingredient of WD-40?...
Fish Oil.
The product began from a search for a rust preventative solvent and degreaser to protect missile parts.
WD-40 was created in 1953, by three technicians at the San Diego Rocket Chemical Company.
Its name comes from the project that was to find a 'Water Displacement' Compound.
They were finally successful for a formulation, with their fortieth attempt, 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.
