I have some other options for you,
#1 A spray bottle and a small furry pet that you can spray cleaning solution onto and then stick the needle in to clean it.
#2 A small child holding a piece of wet velvet.
#3 Electric toothbrush at your desired angle. Press the button to turn on, clean brush, turn back off.
On a serious note, Your doing fine Husky, you seem to have your options covered. I too have loads of things to use but stick to cut off paintbrushes to clean cups, mix paint, clean needles. Steve Leahy uses a paintbrush to mix paint in his cup.. Check him out on a Monday night on FB 11pm UK time.

PS: Apart from the electric toothbrush option, all other suggestions are my warped mind and sense of humour kicking in. I will say I rarely let it out due to the fact that people these days get offended at the slightest and I apologise in advance if anyone takes this seriously.
