I’m sure it’s been asked multiple times in this forum, but what’s the most efficient way to clean scope/bino glass?

Sounds like a question for Big Stick.

VERY soft lens brush to remove anything big or loose and then I use Zeiss moistened lens wipes for final wipe and clean.

Binos, put them under running water to loosen up or remove any dirt. Shake them and blow off the excess water followed by a microtex cloth supplied by the Mfr of the bino.

Scopes, use canned air to remove loose dirt and then a damp microtex to clean them . You can use a moistened lens wipe after making sure there is no debris on the surface.

Can't be done without damaging the delicate lenses. They make new scopes and binos everyday - best to just replace.
