I tried a new (to me) tweak this weekend, by cutting Q-tips in half then sticking the stick part into my dremel tool, then applying either Deoxit (for cleaning), or ProGold (for clean up and conditioning), directly to the Q-tips, I was able to easily clean PC plug blades and speaker cable spades. Worked really well getting some old QuickSilver Gold off the spade connectors. You will go through a lot of Q-tips to do a really good job on dirty stuff, but the Q-tips are soft and you shouldn't hurt the finish of whatever you are cleaning if you go at low spead and do not press too hard. You can use dry Q-tips to clean off the Deoxit residue and when finished you can still apply a thin layer of Pro Gold using the applicator brush.
