Glass Polishing Kit For Deep Scratches ? Eastwood Glass Polishing Kit - Auto Scratch Remover

Depending on severity, these might be an option. I haven't used it personally, but seen pro's recommend them for glass restoration or when replacement is not an option.

I use the professional detailers custom made top secret and overly priced acid bath.... aka white vinegar in a spray bottle. We have some of the hardest water in the nation. Go over the paint with the vinegar, let it soak a few minutes (not too long), then wipe it down with a mild detergent from Meguiars or another respected brand with a clean and soft cloth. Then check for additional spots. If you have any do the spray and wipe with the white vinegar again.

Dry by hand and seal it all up with the "Ice" wax. It will fill in any tiny etches left from the removal of scale. It will look spectacular.

Bump for Bio Clean used some of that once and it is good stuff.
