How do you clean XLR connectors?

Tonight I got the 'ProGold' contact enhancer out and cleaned my spade lugs and speaker terminals. Wow, much more open, and parden the pun, much cleaner sounding. My system is all balanced, thus the interconnects have XLR connectors as does my electronics.
The question is, how do I clean the male pins of the connectors and the female XLR's? Is there a tool for this, or do you just use a Q tip?
In advance, thanks!
