Mark - I have been using one of those screw on, pointy plastic nozzles you get with the tubes of silicone (tubes not gun cartridges). I just drilled a hole in the bench, stuck the nozzle in and filled it with den- alcohol, push the tip in (threads hold it there) , and any paint would be dissolved by the alcohol, can't see why you could not use water windex etc - pull it out, give the brush a quick squirt to blow out the droplets of cleaner and it is right to go. Lately I have been leaving it there until next use, as when the nozzle is jammed in there there is little evaporation and you know the needle will not be jammed with dried up paint residue or something. I am at work, otherwise I would post a picture.pete
