Just use WD-40. It will clean, lubricate and clean the contact surfaces. I
fixed the sparking roller contacts on the roller inductor in my Gates that
way, and it also made it turn more freely.
I find it also cleans noisy potentiometers. I used to have to spray the
a.f. gain control on my 75A-4 about once a month, using the stuff sold at
the local electronics supply store just for that purpose, or it would become
scratchy and noisy. I gave it a good dose of WD-40, and it has been quiet
for almost 10 years now, with no recurring scratchiness.
