Sometimes a noisy pot can be cured just by rotating it back and forth quickly ten times or so. Often the pots that become noisy do so because they are the least used ... I suspect that's your problem. Every week or so on my preamp I turn the selector switch and the pots back and forth a couple of times ... on the advise of a technician at a well known manufacturer. I'm not sure if it's good or bad, but so far I have had no problems with noise or other failures.
So you might not even need to use cleaner, but of my suggestion doesn't work then the other Sean (above) is right on the money.
