This is really bad advice, about hot water. When I was in New Zealand once, where you sometimes still encounter faucets with a separate hot water and cold water tap, I accidentally ran my glasses through the very hot water coming out of the hot water tap and it completely destroyed the coating on the lenses, it was as if I had run sandpaper over them.

The water only needs to be lukewarm. i.e. rinse glasses with lukewarm water, then get a drop of dish soap on fingers and rub fingers through a bit more water to dilute the soap, then gently scrub the lenses as you describe, and then rinse the glasses again with lukewarm water. Almost all the water will sheet off.
