Unfortunately I cannot answer that question. Opticians don’t use alcohol to clean glasses, they often use white spirit to clean lenses. Alcohol can potentially damage your frame (if it’s a ‘plastic’ one).
Hot water can damage your anti reflective coating. It can cause it to come ‘loose’.
The rinsing is indeed done to get rid of sand or dirt particles which is the main cause of scratches.
Optometrist here; rinse with cold or ambient temperature tap water (don’t use hot water!), use dishwashing soap without citric acid if the glasses are really dirty, dry with a clean cotton cloth.
There are quite a few documentaries about North Korea, they’re not that hard to find, and they really amaze you when you watch them.
