Yes, the Meg's Hot Rims Chrome Wheel Cleaner contains 5-15% phosphoric acid, as well as <0.65% ammonium bifluoride (the precursor to hydrofluoric acid, an acid which etches glass quite well). I'm glad this thread came up, I was unaware Meg's was selling an OTC wheel cleaner that contained ABF/HF.

PS I can't find anything about phosphoric acid etching glass.
my bad, another dain bramaged , senior moment. I meant hydrofluoric acid. thanks for the correction.:bubba
at any rate, the etched glass will be difficult to polish clear again. cerium oxide will be your best bet (contained in ceriglass) on a glass polishing pad and heavy machine polishing.
