you can use a spray "tuner cleaner" but I use WD-40 most of the time.
WD-40 is abrasive, so it will clean the contacts.
Do not use A LOT, just a couple drops.
Drip it into the control at the solder connections, work the control back and forth a couple times, and if this does not work, then replace the control.
