I have a small can of flux that I bought at radio shack. It is for use with electronics. It seems to help the solder stick and flow when working on dirty connections. I usually dip a finger in it, then rub it on the connection, prior to soldering. It's pretty easy to use. You might try spraying some contact cleaner inside your volume control and see if that helps.
