I don't have (much) experiences with rotary encoders, but I guess
optical encoders that aren't well sealed sometimes might need a cleaning
too, but not the same kind of cleaning that potentiometers need. An
optical mouse react to vibrations, perhaps cheap optical rotary encoder
could do the same. You perhaps should find out what kind of encoders are
used and then search the web what kind of failure is known for that kind
of rotary encoder and as the case may be, how to clean them.
