After a recommendation, I bought some Deoxit Shield in a small tube. I've got the uneasy feeling that there is a spray available, and I should have bought that instead. My instinct is telling me to put a little of this in the switches and pots where possible, after using the contact cleaner. However, I've never used this before so I thought I'd better validate my belief, before I muck something up
That's not the right one- D5 is what you want to clean pots/switches, and if you have the expense, Faderlube F5 tube for pots.

Here's one of the best resources on Deoxit on the internet. The thread was started by Arkay who used to be a very prolific poster on this board but his attention waned and he moved on to stereo components. I get my stuff at the local music shops, they all carry it along with a bunch of other cleaning supplies or Amazon if I'm busy. I pay $15.00 USD for the big 5 oz spray cans that last forever but it would be nice to have one of the little tubes every once in a while for some of the smaller openings. I have both D5 and Faderlube F5 and have had great results over the years using both. http://audiokarma.org/forums/index.php?threads/the-idiots-guide-to-using-deoxit-revisited.207005/
