Do you have tints? I'd be carful using any chemicals on tints. Otherwise, it should be ok. Maybe try alcohol or acetone or Simple Green cuz I know that's safe for glass. I used that stuff on glass when I used to work in a cleanroom.

Not having seen the surface this is of course only a guess, but it sounds as if 'he' tried to use a polish, as IG will usually clean most things on interior glass.

I would second 1:1 IPA (progressively stronger as necessary) isopropyl alcohol / distilled water

no tints. i'm just worried the 1:1 solution of alcohol and vinegar might ruin the defroster.

The copper wiring of the defroster is encapsulated in a thin layer of glass or acrylic so providing you don’t abrade it with a hard/sharp object you should be all right.

Try 'dabbing' a cloth soaked in the 1:1 solution as opposed to rubbing where there are defroster wires.
