I use a brand called Caig De-oxit. It is widely regarded as the best stuff for the pots and input jacks on our gear. You dont want to use stuff from the auto parts store, Its too harsh I found this out the hard way it made the pots in one of my amps feel super loose. The De-Oxit works perfectly.
Below is a link to where I get it
