(This is the important step) Adjust the faucet’s flow to a low laminar flow and run the glasses through water, hitting the top of the glasses first and letting the water flow down and off the bottom of the lenses. It might take a couple passes but doing this will eliminate any water droplets on the lenses.
This final step is also how soldiers get those perfect mirror finishes on their boots and belts!
I did it by using lots of polish, time, and a little (drops of) water. I don't remember holding my boots under a faucet, maybe I could have had an easier time if I'd have known back then. Some folks did use heat guns, but that always made the polish crack for me.
After you’ve water-bulled with the little drops of water how did you get the water off without leaving any streaks? This laminar flow approach collects them up and rolls them off as larger drops so the surface is left dry.
