Who is using open pots now? Most everything is sealed. Cleaners are not going to get inside of most potentiometers unless you are using something like this:

Some people go so far as to drill holes, make all kinds of adapters, etc, which is silly to me, because there is no way to get all of the fragments out of there and insure that the wiper will have 100% contact. It would be smarter to replace the pot. The best way to clean a pot is to use it often. The wiper will clean the contact path.
There is a De-Ox-It Fader for fader wipers and open, stepped, pots. I use keep the Gold use limited to contacts and electronics.
