Minor nitpick.
Actually acids do not attack glass. Alkaline solutions will. There are
lots of things in the rain besides the nitric and sulfuric acids, and
I am not saying it wasn't the rain, just that it wasn't an acid. The
acids are highly soluble and won't form a deposit on the surface.

Depends on the acid. *Fluorine acid (hydofluuric acid) is what is used to
make frosted glass lightbulbs.

Sorry, didn't see your post before I replied the same answer!
