WD 40 is a rust prohibitor, and, dries out.
It may destroy your controls.

I've used electrical contact cleaner on several volume pots with good effect. The stuff from radio shack is completely useless imho. It's full of mineral oil and doesn't actually clean anything. Anything good will evaporate quickly and cleanly. If you don't want to order online, they sell some good stuff at the big box hardware stores on the electrical aisle. And I have never used WD-40 for this... Those pots. can be extremely difficult to find a replacement for so you may not want to take any chances. You can use WD-40 to restore rubber grommets and fittings though... I used to use it to clean up and restore rubber rollers and feet in copy machines. It makes them soft again.

p.s. That contact cleaner does evaporate quickly, but while it's on the radio it can damage plastics and paint. Be careful. Don't want to wash all the numbers off of the dial.

I would suggest opening up the pot by prying the tabs open and sanding the tiny disk with fine sand paper just the tiny disk that moves I have tried contact cleaners in the past and they almost never do anything you have to make physical contact, others may have had better luck just my experience
