Lint-free microfiber towels
There are many solutions for removing water from plates prior to drying them. The best we have found are the super-soft microfiber towels that are made specifically for polishing mirrors and glass. These towels have no wayward fibers that end up embedded in the soft plastic surface of the plate as it comes out of the wash-out tray.
These towels are a cheerful yellow color and are 16x16 inches in size, which will just cover an A3 size plate. We sell them in packages of 2 so you will always have one ready to go. Hang them to dry after they have been used for a while. They can also be washed in warm water without detergent if they become a little stiff and gummy from use.
