I never dried my clips, just a quick rinse was all I found necessary. I also found it easy enough to agitate - I just slid the clips back and forth along the top of the slot. The reason I stopped using mine was that I felt it was wastefull because I needed to mix up a lot of chemicals to fill the slots, and frequently I didn't use them up. I still pull them out if I want to print 11x14's as my tray space is limited.
