Here's a towertalk post I made in January, 1998 after some research
subsequent to a thread similar to this one:
>I hope that this will lay to rest the discussion as to what WD-40 is or isn't.
>>From the WD-40 Product Description:
> "WD-40's versitility has made it the world's number one
> multi-purpose problem solver. It has five basic functions -
> cleaning,lubricating, penetrating, displacing moisture and
> preventing rust."
>A quote from Paige M. Perdue,
>Marketing Manager of the WD-40 Company , San Diego, CA. This excerpt is
>from a letter to the editor published in the August,1994 "AOPA PILOT"
>magazine (page 24):
> " It is true that WD-40's carrier does evaporate, like all carriers,
> but it deposits inhibitors that penetrate into the grain areas of metal
> surfaces, removing existing moisture and providing a protective film
> against corrosion. In fact, WD-40 was originally developed to prevent
> corrosion on Atlas missiles and has many applications for all types of
> aircraft." "... It acts as a lubricant, penetrant, corrosion
> preventative, moisture displacer and cleaner."
>>From the WD-40 MSDS (Material Safety Data Sheet):
> Aliphatic Petroleum Distillates 60-70%
> Petroleum Base Oil 15-25%
> Non-hazardous ingredients <10%
> Carbon Dioxide 2-3%
>Aliphatic Petroleum Distillates are also known as Stoddard Solvent or
>Petroleum Base Oil is a lubricant.
>Carbon Dioxide is the propellant in the aerosal cans.
>The WD-40 Company ain't sayin what the non-hazardous ingredients are.
>I make no claims as to the suitability of WD-40 for any given purpose. I
>have no connection to the WD-40 Company other than wishing I owned some of
>As Casey Stengal often said - "you can look it up".
