Checking back in to say thanks to Guysonic for posting this. I just picked up a pack of the Wide Proxabrush cleaners, and went through all of my connectors using them with Caig D5. These brushes are perfect for everything from 3.5 mm jacks down to female XLRs. The only thing I couldn't get them into were female TA4 connectors. One brush held up enough to go through all of my gear.
One suggestion: When spraying the brush with cleaning fluid, do it over a shot glass to catch the overspray. This means that if you work quickly before it evaporates, you'll have fluid that you can keep dipping back into without having to re-spray. If you use a larger glass, the fluid will evaporate too quickly. Waste not, want not and all that.
