WD-40's formula is a trade secret. The product is not patented, to avoid completely
disclosing its ingredients.[3][6] WD-40's main ingredients, according to U.S. Material
Safety Data Sheet
information, are:
51% Stoddard solvent (see http://en.wikipedia.org/wiki/White_spirit)
25% liquefied petroleum gas (presumably as a propellant; carbon dioxide is now used
instead to reduce WD-40's considerable flammability)
15+% mineral oil (light lubricating oil)
10-% inert ingredients
The German version of the mandatory EU safety sheet lists the following safety-relevant
ingredients:
60?80% heavy naphtha (petroleum product), hydrogen treated
1?5% carbon dioxide
The naptha is what makes it work like goo-gone.
Then you have to deal with cleaning off the mineral oil.
