There are many uses for WD-40 (Water Displacement- Formula #40).
It took the maker 40 tries before they got it correct.

Ok, we all know that some people do in fact, use it on their chains. Let’s not go there again; let’s see what other uses there are. I always keep a can in the garage.

In the past I have used WD-40 to drive out the moisture in a cracked distributor cap until I could get a new one. With a hairline crack that you could not see an engine would miss fire and shake like crazy.

I have wet down old plug wires with it as it displaces water and it is dielectric keeping a bike from misfiring in the rain.

It is the best stuff for removing sticker residue, pine pitch, tar and some markers because it is chuck full of solvents.
(Works far better than Goo Gone)

An old hood latch with thick dirty grease that will not release, 10-4 on the WD-40, it cuts grease with ease.

In the winter here when it gets down to around –20F, the door locks on cars tend to freeze. I take a can and put it in hot water and then use the little red tube that comes with the can and spray some into the door lock. The warm mixture melts the frost and displaces the water leaving a fine layer of penetrating oil that in turn keeps out future moisture.

You can use it to waterproof golf shoes.

Wipe down guns with it.

What do you do with it?

 

countless things lol

 

One thing that surprised me is that it sucks for removing stubborn lug nuts. The threads tend to gall. Even PB Blaster sucks there. There is nothing like a good thick motor oil when it comes to lug nuts.

 

best thing for lugnuts is to coat the threads with a lil grease b4 tightening

 

Speaking of Lug Nuts there's another Guy on here that loves the stuff too
I wonder when he'll weigh in with his list of really useless uses ......only
kidding ya man

Anyway here's the official 2000 list from WD40 customer feedback

 

Oh yes, there are many uses.

But the best one.... and many don't know it because I keep it secret....
It's an aphrodisiac.
Chicks love the chit.

It works great as a cleaner/degreaser.
You can freeze bees and wasps with it, too!
Someone even mentioned using it on leathers... very nice!

I used to use it on tools as a lubricant/H2O displacer/rust preventer. It still works great, but Eezox is better.

 

I've heard that you don't spray it in a lock, because although it will loosen it right up in the short term, the graphite powder (that's really supposed to be in the lock as the lubricant) will turn hard and freeze the lock up after the 40 dries out. Can anyone confirm this?

Trout, go read the giggle.

 

I've never heard that about graphite/wd freezing.

I have some of both, though, so I suppose I'll mix it together tonight in the garage.
I need to spray some WD around anyway... I wanna get some tonight.. LOL..

 

I took a quick look at the list. There are some really good uses listed like putting it on a hone stone. I have to admit that removing mud from shoes is far fetched and I have to call BS on cleaning fox traps and bowling *****.

When it's -20F outside and you need to go somewhere, who cares.
Just kidding. I think that buy the time the lock is freezing, the graphite is gone anyway.

 

Of all the things I've used WD for, I've never used anything on my sharpening stones. I sharpen all my knives with a dry stone.
My dad always used a little oil on his, but I quit using any because it made a mess and I didn't see a difference from using a dry stone.

Haha! Removing mud from shoes? WTH? Maybe as a water repellent for seams or something... but for mud removal?
Not sure about fox traps. Maybe the foxes don't care that it smells like petrol? lol..
Bowling *****... ok, I'd do it..
