Thanked: 317The reason for the anecdotal evidence of it's hydroscopic properties is actually up above in one of the previous posts.
The reason is that it is mostly made up of solvents, and leaves VERY little lubrication behind. So, it will strip away all the oil/grease that is protecting a piece of metal from oxidation, and not leave enough of it's own lubricant behind to do anything useful in terms of lubrication or protection.
That's why I used to love it for cleaning my bike chain when I commuted on a bicycle. It would dissolve all the old grease, drive out all the water in between the links, and flush out all the road grit in the process so I could re-lube the chain after it dried. Once I started doing that every week instead of just adding more chain lube, my chains started lasting about twice as long.

its def not for face.
ive met several old men that swear that spraying wd40 on your knees is better than any arthritis medicine...
found this page saying the health effects of it.

WD-40 literally stands for Water Displacement, 40th attempt. That's the name straight out of the lab book used by the chemist who developed WD-40 back in 1953. The chemist, Norm Larsen, was attempting to concoct a formula to prevent corrosion — a task which is done by displacing water. Norm's persistence paid off when he perfected the formula on his 40th try.
i think if your using it on machinery or whatever the parts should be wiped and done up with manufactureer reccomended oils.Last edited by The0ctopus; 05-25-2009 at 02:44 PM.

The only thing WD-40 is good for is cleaning grease off of your hands in the shop and getting those stickers and labels off of jars. It will gum up guns or fish reels big time.

They may have reformulated WD 40.

I tend to think of WD40 as a 'Jack of all trades master of none'
As far as I know it is water based. This came up when there was talk of it containing silicone and being potentially harmful to catalytic converters, which as far as I know it is not. I've had problems with it damaging certain paint finishes and 'O' ring materials.There are better rust solvents,better lubricants and better corrosion preventatives available. I seem to remember an article in the Daily Telegraph (UK) where Dr James Le Fanu suggested spraying it in arthritic joints.'Living the dream, one nightmare at a time'

Everyone knows you only needs two thing to fix it all : WD40 and duct tape.
If it don't move but should - WD40
if it does move and shouldn't - duct tape
Myself I prefer automatic transmission fluid on my blades - it's clean, smells good
or Hoppes.

now i will note this, its not supposed to be used in firearms because firearms get incredibly hot with use. from revolvers to ak's theyll flat out melt your skin off if your firing them fast/long enough.
i would imagine that this heat is why they say not to use it on guns,
also, NOONE recomends wd40 for long term protection, its to clean, and then wipe with manufacturer recomended oils, which would vary between stainles and carbon, guns and engines etc etc.. might it be OK, yes, but definitly not recommended.
it doesnt lube for long, if you put it on a squeaky chair itll be squeaky again in no time. the only times itll seem to last long is when it actually loosens pre-existing oils.
it is known to carry the same ingrediants as stoddard solvent :

that eezox better be some good stuff, its exponentially more expensive than wd40, over 3 dollars for 1.5 ounces, my wd40 im lookin at cost the same, and is 13.5 ounces, plus these can come in twin packs and stuff.
ive been trying and trying to convince my buddy not to use 3in1 on his guns. but it says guns on the bottle so he wont listen/.Last edited by The0ctopus; 05-26-2009 at 07:46 PM.
