Sadly, I’m in the practice of using it to clean and lubricate my sliding screen door, and it works pretty well. (I clean the bottom rail first using soap, water, a scrub brush, and a hella lot of paper towels, then spray on WD-40. I do this probably yearly.)

I like Tri-Flow, but honestly, for something you don’t intend to lube on a periodic basis and that is likely to trap dust and dirt, you shouldn’t use a liquid lubricant at all. Use graphite or another dry lube like Dry Slide, or a least a non-hygroscopic viscous coating like beeswax, which is well-suited to loose tolerance sliding parts like doors and drawer slides.

I use 3 in 1 Oil or in a spray [Tri-Flow](http://www.triflowlubricants.com/Tri-Flow_Lubricant.html) and have good success with them both.

ETA: Take Stranger’s advice on the Dry Slide.

Not even close. Mostly petroleum based hydrocarbons. There’s no fish oil in WD-40.

Maybe it’s the fragrance? Seriously, even if it is that good for all sorts of uses I wouldn’t be able to stand the smell all over my house.

I do like that the answer to the trivia question “What does the WD stand for?” has managed to stay in my brain for many years and it has come in handy a couple times.

I think we’re misunderstanding the term “Fish Oil” here. It’s not oil squeezed from fish, it’s what you spray on fish to make them swim faster and quieter. Until, of course, they’re eaten by halibuts.

Spray it on whatever else you’re using as bait. Fishermen swear it works, but I’ve never tried it myself. Of course, fishermen drink a lot.

And here I was wondering how hard it would be to get a big fishhook through the can without it blowing up in your face…

Nobody likes a fish who squeals. That’s why you can never get one to talk.

Didn’t feel like taking the time to read the thread before responding and see the other 4 posts that said this, including the _2nd post in the thread_, and the one that listed the ingredients?

> [@moldybread](#):
>

See the [official website](http://www.wd40.com/about-us/history/) for details, but WD-40 stands for “Water Displacement - 40th Attempt.”

(Or, as silenus so succinctly stated, “yes”).

> Actually, it is a paraffin distillate (white spirits or mineral oil), though the exact composition is a trade secret. It was originally used to protect the bodies of Atlas missile (which had a bare, unpainted skin) during its brief operational deployment, although once the booster was decommissioned a more typical beeswax or cosmoline-type protectant was used in storage. NASA objected to the use of WD-40 on the Mercury-Atlas SLV and Atlas SLV-3 because of the potential for outgassing and inadvertent combustion, but ended up having to leave the coating on because of the highly corrosive atmosphere at the Cape.

It comes in banana flavor? Yum!  
I think there actually is some industrial cleaner/solvent/lubricant that smells like bananas but I can’t remember what its called.
