Removing the "tempered" etching from glass

[wrndln]

I had a rear window glass made for my pickup and had it tempered. Unfortunately the glass tempering place etched a label on the lower corner of the glass. The fingerprints and smears around the etching is not a problem, just the etched lettering. I don't want the etching on the glass. Maybe they have to do it by law. Does anyone know how to remove the etching - some compound? If the glass is slightly wavy after the etching is removed, that's OK.
Thanks for any advice.
