Noisy pots can usually be cleaned up easier than you think. Often no solvents are necessary and if you do use a solvent, use as little as possible. I find that most of the aerosol cleaners dispense far too much solvent and can affect the "velvety feel" of the pot. Never try to "flush" the pot with a lot of cleaner.
The first step is to just exercise the control from end to end about 15-20 times. Potentiometers are self-cleaning for the most part, the wiper is often capable of scraping away whatever is contaminating the element, usually just environmental crud or some oxidation. Wiggling the shaft can aid in clearing away the corrosion or contamination.
If that doesn't work, the next step I try is a few drops of alcohol. 70% isopropyl is fine and I use a small bottle that has a metal applicator tip that works great. Exercise the pot more and see where you are, you should have some great improvement at this point. A little more treatment with alcohol should clear up any remaining noise.
If it's still exhibiting problems, I will attempt to use Caig Green - again just a few drops and work it again. If at this point you still have problems, replace the pot.
There are generally two basic types of pots in use in audio gear: plastic element and carbon element. Using any naptha based cleaner generally does not work out well, the solvent interacts with the plastic element as well as other plastic parts. Carbon element pots do seem to respond well to naptha based products but starting with nothing and moving to alcohol will work most of the time.
