So this is a serious answer. The air we breathe out is mostly nitrogen, with some oxygen, some carbon dioxide, some water vapour, and a tiny percentage of other trace elements. Unless you've just breathed in something loaded with particulates, such as cigarette smoke, breathing on your lens won't cause any harm at all. Any saliva in your breath is sterile and usually PH neutral, so the idea that you might be breathing acid onto the lens is really just an internet myth. There might be some germs in there if you've got an infection, but they won't harm your lens since you'll be wiping them off with the microfiber anyway.
Sorry I didn't get the humor but that's temporary thing, fly to georgia we will then exchange with some
Argh.. back to the lens, I'm preparing for this operation like a surgeon in hospital.
Soft brush, microfiber cloth, IPA, distilled water, medical gloves and lot of my nerves.
Breath or not, something must be in contact with the rear element to take that fingerprint off. That's the main problem I'm afraid of.
