The salt acts as an abrasive, the alcohol as a polar solvent
Salt is not very soluble in ethanol.
Therefore does not dissolve, and its only purpose is to act as an abrasive.
Alcohol acts as a solvent, that will evaporate cleanly.
If your very cheap, you can use rice and hot water, but gotta put in a little bit of elbow grease.
Remember borosilicate glass is also used in scientific labs, is very stable, and tolerates somewhat rapid temperature changes, and various 'harsh' chemicals.
Careful with lye, it has a tendency to etch glass, and after repeated use will most likely crack.
