I would say clean only as needed. Use a big blower bulb like the Giottos (looks like a 1940s A-bomb, stands up by itself and does not roll off the table) to blow the occasion dust off, though.
It is best to try to minimize getting nose prints on the lens. I always pull back the retinal camera joystick, and then move the table up (our Reliance chair does not move) and have the patient put his chin in. On the Cirrus, I can't do this. I tell the patient to carefully put his chin on the left side of the chin rest. This is a difficult concept for some, and they seem to aim the nose for the lens before I can stop them.
I found ether to be expensive and volatile, the majority of it evaporated instead of being used. Cotton ball (not Q-tips) and alcohol work for me.

.Quoting Noelle Pensec <npensec@xxxxxxxxx>:
Thank you everyone for your GREAT responses. I suspect that kimwipes and maybe some salt crystals were the culprit in our scratched lens. I really appreciate all the tips and advice. Hopefully this won't ever happen again! One more question to add: does anyone clean lenses preventatively (i.e. daily) or should it be done only as needed? Thanks again for all the great information!
