Anywhere there’s a sink in your house, you should have a spray bottle of dishwashing liquid diluted to the strength used for doing the dishes. Spray the lenses, work the solution over the lenses with your FINGERS. Rinse. Then dry with the appropriate towel, Kleenex, paper towel, etc. proceed to the nearest window hold the glasses up to examine for smudges, and exclaim loudly (as my sister would when performing the procedure with my own glasses). “Wow! There really is life on Mars!”
