REPAIR AND ELECTRONIC CLEAN UP QUESTIONS

[Joe(TX)]

I have some glitches on a potentiameter dial which I believe to be dirty contacts. How would I clean this? Alcohol and cotton swabs? Also if a potentimeter dial is defective, how would I determine this? Thanks I would appreciate all advise!!(also see my posts on the Nautilus MF) Joe

Radio Shack used to sell a aerosol pot cleaner, I've used it a couple of times and it seems to work pretty good. Otherwise, alcohol should be fine. Not sure about defective... you mean burned or pitted? If cleaning makes no difference, the I spoze the only option is replace.
