Cleaner for volume control

Kirkus, thanks for the benefit of your experience. I'll follow your lead on pot cleaning.

Thanks to all, I'll go with the Caig Fader Lube & report results.

Caig Deoxit worked wonderfully on the volume contols of my venerable MFA Luminescence Pre-amp and the tube bias switches on my MFA mono amps. They've been out of service for a number of years. Volume controls were noisy. Amp power tube biasing was impossible due to poor contact.

Judicious application of Caig did the trick.

I also "worked" the knobs and switches repeatedly which helped the Caig do its job.

And, finally, I treated the tube pins and sockets with Deoxit Gold after Deoxit.

Highly recommended.

WD-40? on contacts?

I'd as soon do that as use Armor All on a record.
HEY, I DID use Armor All on a record! ONCE. 30 yrs ago.
Absolutely NO surface noise, a ruined stylus (gunk) and a new replacement disk.
