I use water to clean mainly (always between colours)and then when I finished and ready to pack away I give it a quick blast through with some autoair airbrush cleaner, I then run some more water through and then break down the brush and use some small airbrush brushes (like miniature toilet brushes
)to clean out the nozzle and the cup getting rid of any left over signs of paint and give the needle a quick wipe down.
Hope that helps.
