DeoxIT works on the ANC-4 pots that go scratchy, and lasts a couple
of years at least.

It does change the feel of the pot temporarily, from instantly free
turning, to sluggish after a day, and then it fades back to free
turning. I don't know what goes on inside during this.

You have to use spray-on on pots because there's only the tiny access
hole. The brush-on vial is more useful in general, for all those
rf and audio connectors that never have worked right. It does a great
job making them trouble free.

and there are other applicators and sizes too. The brush vial lasts a long
time, even though it's tiny.
