Acid on windshield

one of the guys in the shop accidently used, I cant think of the name of it right now but it is the strongest acid you can get from Pro(the brown stuff) to clean wheels, anyway he used it thinking it was bug cleaner now there is a haze across the wind shield, we have tried Pro-gold, steel wool, any ideas??? it is like it melted the lamination between the sheets of glass in the windshield.
