Recently I won a very generous PIF and was the lucky recipient of a TWSBI Vac 700. Everything about it was wonderful, and I had it in continuous rotation since I received it. Until a little over a week ago when I flushed it, left it sitting in a cup with a cloth to suck out the excess water, and then I stored it. I took it out today and Yikes! It smells like something is growing in there. I flushed it again (with some dish soap) and tried to dry it out better, but for the life of me I can't get all of the water out of the barrel. I noticed that when changing inks there was always a good amount of water droplets left in the barrel after flushing, but the ink capacity is so large it was never enough to effect the ink so I didn't think much about it until now. Is there some trick to flushing Vac fillers I'm missing out on?
