I've had the same experience with DeoxIT on pots - worked for a short
while, and then the problem returned. That stuff is way too pricey here:
$16 for a 5 oz can!!  Is there gold in it??  Are they charging all the
market will bear, or is the government and product liability lawsuits
making it too expensive to do anything any more?

Whatever happened to General Cement chemicals for electronics?  Years
ago GC made a cheap pink liquid pot cleaner in a little 2 or 3 oz
bottle with an eyedropper-type squirter that worked great for a long
time - it may have been called "Quietrol" or just volume control
cleaner, I don't recall. Remember the multitude of little bottles of
GC chemicals for all kinds of things that used to be on display in
radio parts stores? I've looked for that pot cleaner for the last few
years, but my old-time parts distributor tells me that the EPA made
them take much of that stuff off the market. Younger guys at other
parts stores don't even know what I'm talking about when I ask for it.

I haven't tried WD-40.  I hope nobody tells them it's being used on
radio parts - they'd probably raise the price.
