You can use contact cleaner, or just plain ole WD40, spray and work
the control back and forth a few times to break loose the
'dirt' and then spray again to rinse it away. Wait about 1 hour,
for the spray to dry, before using the radio again. WD and some
contact cleaners are a) flamable and/or b) conductive

I strongly recommend using the appropriate Caig product (available at Radio
Shack) rather than WD-40 or a solvent chosen at random. That will help
ensure that it stays clean and properly lubricated after the cleaner dries.


Huh? How hot a spark can you make with 6 V?

You can certainly make a spark with 6 volts. It's unlikely to happen in an
RF gain control.
