WD-40 Multi-Use Product

“can usually be fixed with some WD-40”

“it's really good for that; and it's passable at other tasks too. For DIYers, it's fine.”

“WD-40 is great for machining aluminum, cleaning grease/other oils”

“It is an excellent temporary lubricant and is the preferred lubricant when installing or removing rubber hoses.”

“It's not sulfurized or chlorinated, like actual (and lower cost) cutting fluid.”

“if you're looking to lubricate something and have it last for a reasonable time, then WD-40 is a poor choice”

“a passable short-term lubricant for quick and dirty jobs, but not a long-term high quality lubricant”

“It's an adequate short term lubricant but its real purpose is to separate water from sensitive materials.”

“all of them better for a specific application, but none of them as universal as the original”

“its value comes from its convenience, affordability, availability, brand recognition”

“You're supposed to use it to flush out the gunk and grime by dissolving it”

“It was also not really intended as a lubricant but as something to get water off equipment and mechanical components.”

“It does lubricate moderately for a small period of time.”

“I'm doing it because I can do that a hundred times before coming close to the time and effort expenditure required”

“all that is left are sharp little crystals, and these are the source of future squeaking”

“WD-40 will wash out any grease or oil in the hinge as well as attract whatever dirt or dust is around”

“you can reapply WD-40 as needed, it may not lubricate the chain but it will clean it”

“it doesn't leave much lubricant behind, which you need for a properly functioning chain”

“WD-40 helped me in the past opening an old door lock”

“it cleans the chain and gets the filth out of the links”

“Use as a solvent, then lube with something better.”

“it's great for dissolving glues, like the glue used to affix government-issued tax licenses to automobiles”

“WD-40 is great for cleaning, particularly threads, but also metal surfaces.”

“there is value to having a product that stops squeaks, cleans rust and de-goo's gunk”

“It's also a pretty good cutting fluid for aluminum.”

“I buy and use it not for lubrication but for eliminating moisture and cleaning.”

“I use it for two things: as a lubricant for machining aluminum and as a way to remove built up, old ass grease.”

“If you use regular WD-40 in a garage it is a degreaser essentially, and your squeaking goes away momentarily, and then comes back.”

“But man did they love it. Went through a couple cans per week I bet.”

“will actually make things worse if there is a functional lubricant in place”

“It's not a good lubricant, as many people have noted, as it evaporates and concentrates contaminants.”

“the main problem with WD-40 is the popular misconception that it's a decent lubricant”

“WD-40 is good for cleaning up old grease or loosing up seized mates more than anything”

“WD-40's advantage is that it's not terrible to get on your skin when you're out working, and it's cheap.”

“it not only has poor ability to stick around under load, but also likes to oxidize, forming a varnish or horrible goo”

“a brand name that can be trusted to work well more often than most alternatives”

“Being a recognized household name makes it infinity less likely you'll have someone complaining if you use it in a "nice" setting.”

“Lubricates well enough for 99% of the homeowner things it gets used for.”

“It's just not a particularly good one in a lot of use cases.”

“Very little in the way of friction reduction.”
