Dry contact cleaner spray? What could that be...?

WD-40 is an old, and rather worthless product that is a product of the WWII
effort 50 years ago. WD stands for 'Water Dispersant' and 40 is how many
prior versions failed. Frankly, if they'd stopped at 39 we'd all have been
just fine. It is a poor lubricant, and an even poorer penetrant. HOWEVER,
some folks claim it works well for cleaning electronic switches and pots.
All I say is, make sure they have fully dried before you use them!

WD-40 is very cheap, but pots are not...

A better product is LPS-1, which is a greaseless mil-spec lubricant safe
even for clean room use. (FYI, LPS stands for lubricant-penetrant-solvent).
Once again, make sure it's dry first. I know one antique radio tech (and a
good one he is) who swears by LPS-1; claims many miracles in it's path.

Greaseless lube is important, as grease will attract dust, which forms
swarf with the grease. The swarf is essentially a fine grinding compound
which will soon wear out the pot completely.  

Maybe this helps.
