You could always tell which cupboard in the chemistry room the HFl was in because the glass window would be etched opaque.

But yes, today nearly all glass is etched with a fine grit sandblasting. Any glass shop should be able to tell you where to get that done. Your glass is doubtless tempered so it would have to be done carefully and very lightly so as not to weaken the compression skin. Again, an expert who does this stuff should be consulted.
