I can understand this if your doing it professionally, or if
it's the sort of thing you find you need to quite often - but
are you convinced that the end result is substantially better
than a quick squirt of WD?

As a professional, I don't like things coming back. Period.

As to using WD-40, some time ago, I acquired several 5-tube
table radios at an estate sale. Basically worthless, and with
all the usual age related issues you'd expect. I tried WD-40
on the volume controls. Yes it works (are you paying attention
Phil?)

I just don't feel comfortable using it.


I never had a problem using WD40 on anything, except pots would need more
at some point. Just does not last as a lube.

Um, why do you think WD-40 is anything but a rust preventative? The rest
is simply marketing hype.

Much like you can lubricate anything with H2O if you want to, but there
are better products DESIGNED for lubrication, etc.

The fact that WD-40 CAN lubricate, doesn't mean it SHOULD. it wasn't
designed for that purpose and so is third or fourth choice at best.

Emergency usage, sure, then clean it off as soon as you can, unles syou
don't want the item to rust. Use it on something that I care about working reliably, never.

After all - that is why we have brains, so we can think about what we are
doing and apply the best solution.

I think an oil based and mineral spirits based product used like WD40, as
well as Caig Deoxit, will stay on the item to be cleaned longer. Longer
cleaning, better. You can always wash off later with non residue cleaner.
In fact, one of the best cleaners Cramolin Contaclean, says to wash off
after cleaning. There are a number of products for electronics that have a
base carrier and a type of oil, might seem unfair to pick on WD40. Plenty
of non residue cleaners or electronics. The CRC 2-26 somewhat similar to
WD40, says right on can, improves electrical properties, plastic safe. I'm
not seeing much difference in ingredients. There are far fewer only
lubricants, Caig Faderlube being one.
