I suppose I am cautious as different manufactures of glass lenses for different uses recommend different procedures. Takahashi for example recommend only lense cleaning fluid and cotton for the coated flourite and uncoated interior lenses and for some particular lenses in the instruction manual specifically advise against the use of alchohol or specific cleaning additives.

The recommendations for miscroscope lenses are similar (from the links ) as, I would imagine, micro scratches from wipes will become a problem over time and the lenses must be absolutely clean. Perhaps this is similar to high focal length refractors except they are only cleaned when absolutely necessary. I suspect the answers is always, which refractor, which glass, which coating, what does the manufacturer recommend.

Things that would not affect a camera lense may affect other lenses.

Most SCT correctors on the other hand are forgiving, have robust coatings , probably similar to a camera lense, and are going get moist and dirty without this being a major problem in the short term.

I have never ever even as a Pro photographer cleaned a sensor, ever, rarely ever clean lenses except with a "Lens pen", and use them on my eyepieces also

THIS is how to clean scopes and cameras
