Quick question: in reviewing your instructions / video on 3800 / 3880 maintenance procedures you indicate using a Q-tip for cleaning the capping station gasket and wiper blade. I have also noticed in the video(s) what looks to be a plastic long-handled foam ended cleaning stick. Do you have a preference? Have you seen any cottony residue from using a Q-tip? If using the plastic / foam stick do you have brand that you prefer?
