I have seen repairmen just twist a knob back and forth repeatedly and got rid of pot noise . One told me it was from not moving then enough .



This trick can work well by getting a little mechanical cleaning action of the all-important contact surfaces but I must include the important caveat that if the control does not have enough of the original lubrication components left in the critical areas, it may also be a recipe for the premature wear of contact surfaces such as the carbon stripe in a potentiometer. Eventually, this could result in such wear and tear that the control will have to be replaced.

Good thing to know in a pinch, but it is highly recommended that if excercising the controls brings joy, consider it a sign that you should get the proper cleaner/lubricant inside that control as soon as conveniently possible, don't just keep doing the same thing over and over - and in most cases, without the cleaner, you will have to do that. And then one day it fails entirely...
