        I once in an optics lab *suggested* (lucky me) breathing on a
component to moisten it before wiping. The instructor *yelled* at me (only
time) to make sure I didn't carry through. (CO2 + water in your breath =
dilute carbonic acid? He didn't amplify on what all is in breath, but he
made sure I used IPA or de-ionized water or something after that.)
        Not knowing the proper solvent, I'd tentatively suggest iso-propyl
alcohol, but would avoid breathing on optics (or media) if at all possible.
It may be MO disks are sufficiently rugged it makes no difference, but that
formative experience has convinced me it's not a good habit to be in.
