Has Anyone Ever Found A Use For WD-40?

The company I worked for had about 200 U.S. Service Techs. Techs started spraying WD40 on bearings as part of preventative maintenance. Not an approved procedure, but Techs will do things via word of mouth from other techs. Customer machines started prematurely failing. WD 40 was actually destroying and flushing out the bearings grease/lube. A Service Bulletin went out explain not to do this, and why. A lot of grief caused. That's when I learned to verify before trying things on my own, or via word of mouth.
 
wow, people have sure relayed the intended and extrapolated uses that I never would have guessed!


I saw some blurb on the Internet about using it to clean the commode....

A spray can of the stuff with the plastic straw is my go-to for straight through power tapping with wire size gun taps.

I run a constant pressure spray directly into the flutes from behind while running forward. Not it's intended use but works well and cleans up much easier than any other cutting fluid.

Piggybacking on what Mike said.
A lot of machinists, myself included, use it when machining Aluminum. I'm talking lathe and mill work. It helps keep the Aluminum from sticking to the tool, keeps the tool cool, and improves surface finish.

I spray the inside of hoses before installing if they are tight. They will slip right on with minimal effort. As mentioned earlier, it is great for cleaning oil, tar etc. Years ago, a neighbour of my brothers was over and lamenting that his truck (highway tractor) had a clicking noise in the front of the motor. He said that he had taken it in and had spent many thousands of dollars to have the issue discovered and fixed. After a few tried, they had changed most of the peripherals on the from t of the engine but no change. He asked my brother if he would have a look. He went over to thee guys place and had him fire up the truck. There was a very noticeable clicking noise that increased and decreased with RPM. He asked the guy if he had a can of WD-40. The guy gave him a quizzical look and said yes. Brought the can and my brother sprayed it on the belt and the sick went away. The guy said "you gotta be kidding me!!!". My brother explained that he had seen this before. The belt was sticking to the pulley and would make a snapping noise when it let go.

Many years ago (about b35) I was lamenting that I had no idea what to get for my wife stocking for Christmas (I think we were just dating at the time). She suggested perfume but I said I had no idea what kind to get. She said "just get something you would like" so I put "Hoppes #9" in an old perfume bottle and put that in her stocking.
 
LOL, but may not attract women, may be more of a repellant.




WOW! Good to know......I need something for that!
 
About all I use it for is on my reloading press, just to keep it from rusting.
WD-40 works good on carb gaskets to keep them from sticking when disassembling.

I use for a rust penetrant, GM stuff, used to be called "heat valve" lube...PN 88862628
It's the sheet !!:cool:
 
Darn I was going to post something along the lines as it smells good. But you may get some unwanted attention if you use it for that! LOL
 
If you've ever seen somebody given one of those horrible "Don't Park Here" stick- on-warning labels that's been plastered on their car's window, tell 'em to stop trying to scrape it off, that won't work, and they'll damage the glass. Instead, tell 'em to just soak the label with WD40, and wait for it to completely saturate the paper. When it reaches the adhesive layer, the WD 40 will quickly solubilize (degrade/soften...) the adhesive. But it must first have soaked completely through the paper layer... Then you can just wipe off the whole mess with a paper towel or a rag... It really does work perfectly.
It will probably be just as effective on all those other political/school/etc paper bumper stickers, but using WD-40 on any type of painted, chromed, waxed, clear-coated, metals or any of the modern polymeric surfaces opens up the need to do preliminary solubility testing on an out-of-the-way spot.
 
I use WD-40 on lug nuts when I tighten them. It is enough of a lubricant that the surfaces are not completely dry when tightened, and helps assure most of the torque exerted goes into clamp load and does not gall the threads or the wheel. Later it just evaporates away. I will also use it as a penetrating oil, but obviously there are better products for that application.
