Audio System Mods, Repairs & Maintenance

Hi,
I have a question about cleaning pots and switches in audio equipment: over time they corrode and cause noise and/or intermittent dropout. My Audible Illusions Modulus 2C had the left channel on the line input sporadically dropping out and causing lots of scratchy noises, and I managed to get it working (better) simply by toggling it on and off multiple times. Is the best method just to spray contact cleaner in the switch, or maybe get some conductive grease on the contacts? I will take a look at it to see if the latter is even possible.
Also, on my office / computer stereo, the Denon receiver has a variable loudness control that is very intermittent, and I already tried to spray clean it a while back. I think this one will require soldering a jumper on each channel to bypass the pot's wiper contacts, and run it "flat" - which is how I prefer it anyway.
