That kind of cleaning can make what seems to be really crappy glass almost useable Steve.

When you have glass that has machine oil on it from the manufacturing process just wiping it with a towel wetted with even alcohol just loosens stuff on the surface but often does not actually remove it all, especially from scratches or nicks.

The pickling pulls stuff of the glass and chemically changes the surface tension of oils so it lets go of the glass.


At least I think that is what is going on.

And you can clean a lot at once as long you don't let the colors get mixed up.

Its not bad at removing label gum as well.
