Follow Ka Pow and Mose's directions. You won't go wrong.
You'll need to use white vinegar.
Keep your glass dampened with vinegar for 2hrs.
Flush with lots of shampoo and water. Dry. Inspect.
Be careful of acid-based stuff. It works.....but on glass with lots of ultra-fine scratches and stone chips, the chemical will migrate into these micro-fine fissures and cause haziness...thus permanently damaging the glass. Some side mirrors that're coated at the factory, can also be damaged by these strong acid-based chemicals.
