Potentiometer fix?

L-NJ already said that.

So if this were a modern plastic bodied pot, would squirting it with, say WD-40 be appropriate, because grease would be compacted under the flimsy wiper?

Once Im sure the plastic body won't be damaged by the solvent, I use GT85 - you'd think the PTFE content would interfere with the wiper contact but it never has yet.

I would also suggest WD40 (as it's something that most DIYers have immediately at hand. Just a drop (don't drench things too much). After some time, it may need re-doing. But most pots, once they turn noisy, also tend to need an occasional re-do, regardless of what you use as a cleaner/lubricant.

GT85 is sold in direct competition to WD40 and is rapidly catching up.

Its more expensive but the PTFE additive makes it worth the extra.

This was for rotary pots, not sliders where there is much more opportunity for crud to get onto the track. As for WD40 etc on congealed?/compacted grease. Perhaps detergent squirted in , if compatible with the plastics.
