From what I've been told WD-40 means water displacement 40th try so the 39 tries before it didn't work.

Water is the oddball, expanding as it freezes, but it is so common it tends to make us think it is "normal".

Loosens stubborn zippers.
lubricating a zipper with paraffin works better
Lubricates and stops squeaks in electric fans.
Actually after it drys...it will attract dust and potentially jambup the fan
Lubricates fan belts on washers and dryers and keeps them
running smoothly.

Folks even spray it on their arms, hands, and knees to relieve
arthritis pain.
Old wive's tale...see formulation below
P.S. The basic ingredient is FISH OIL which is not harmful
see formulation below
All being said and done. WD-40 is not much of a lubricant at all. I use it to displace moisture from the distributor cap on a boat engine.PaulChristenson said:Formulation
Main ingredients, from the material safety data sheet are:
50%: Stoddard solvent (mineral spirits, also commonly known as dry cleaning solvent)
25%: Liquified petroleum gas (presumably as a propellant, carbon dioxide is used now to reduce 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
It further lists flammability and effects to the human skin when repeatedly exposed to WD-40 as risks when using WD-40. Nitrile gloves and safety glasses should be used. Water is unsuitable for extinguishing burning WD-40.
