Switch to Forum Live View Refuting "WD-40 is not a lube".

I quite often see "WD-40 is not a lube; it's a water displacer" written on various forums.  It was on my cycling forum today.  Here was my reply to the misguided poster -

To say it isn't a lubricant isn't true. Even water is a lubricant and this is proved by the existence of hydroplaning, ice-skating and skiing and a few other things. Of course, water, as well as WD-40, might not be the best lube for a given application but to claim it isn't a lube is just not true. Spray WD-40 on a rusty, squeaky bike chain or a squeaky door hinge and I'll guarantee that the squeak will go away. Whether the squeak will be banished for longer with a thicker lube is immaterial to this discussion.

WD-40 has, as its base, a lubricant that is thinned by a propellant - much like my beloved Homebrew chain lube. Try this exercise as I have many times - find a piece of old mirror and spray onto that (laid flat) mirror anything that claims to be a lube that you'd like to test - like WD-40 or Homebrew for instance, or any other spray lube. Now let this mirror sit for a period of time (hours, days, weeks, months - your choice) and then look and feel what's left on the glass. With water there will be nothing left, proving that it's not a good long-term lube. With everything else that has the gall to claim it's a lube you will have some form of oily, greasy residue.

I've gone one step further than this - I've had an open cupful of WD-40 sitting on my workbench for about 6 years. All the propellant has long since evaporated and I'm left with a wonderful thickish oily brown gooey lube. What its properties are I don't know as I'm not a chemical engineer or a WD-40 chemist but there is no-one who would look at and feel this stuff and say with a straight face that it's not a lube.

Before you get your undies in a knot, go back and read where I said "WD-40, might not be the best lube for a given application" but then that goes for all the oils and greases that exist. After all, we wouldn't use axle grease to lube a turbocharger would we?

Mike, What a terrific response. We agree WD-40 may not be the best lube around, but it certainly works for most applications that require light lubrication. The fact is, that WD-40 is a multi-use product with many basic functions, including as a rust inhibitor, remover/degreaser, penetrant, lubricant, etc . We love that our users like to experiment and tell us how they've used WD-40 to solve their problems. Please keep sharing!Wink

Loved your reply, Mike.  And your non-scientific testing/experimentation.  I will have to try that putting WD into a container and let the propellent evaporate.  I can think of many things that would be perfect for.  Just a bit on the end of a toothpick, or a little on a q-tip - I can imagine the many uses.

As you said, it may not be the lubricant for all uses.  But it is a lubricant, for sure.  

No undies' knot here.  ;)

I thought they sold WD-40 grease tubs.  Has anyone seen these around?

I have not seen these myself but I sure think it would be handy to have a thicker version of WD 40 available
