Thanks for all the great suggestions!
I have tried contact cleaner and WD-40, but no luck yet. The pot. is
spring clipped to the back of a range switch, and the pot. shaft runs
through the hollow shaft of the range switch. The pot. isn't stuck on
the range switch shaft. I can't use a hammer until I remove the
potentiometer, because of the spring clip. Maybe things will start to
move when the spring clip isn't pulling on the pot. shaft. I'll pick up
some Blaster PB and go back at it tonight.
btw, I have heard that Kroil might be better than Blaster PB, but I can
only find Kroil online and I don't want to wait a week for it to ship.

I'm looking for suggestions on how to deal with a frozen
potentiometer. It's on the back of the vertical gain switch on an Eico
435 scope. I tried contact cleaner and a bit of torque, but it won't
budge. What else could I try?
