Ethanol (alcohol) has been used as a lens cleaner for many
decades. I know the navy used it to clean periscope optics
on submarines during WWII. So I don't think it would be a
problem. Chlorine (bleach) may not harm the glass, but it is
corrosive as hell and I would not trust it around my photo
gear.
