    Tape a pad of paper towel soaked in GooGone to the spots and let the solvent soak in for at least half an hour to soften the spot. Use the edge of a plastic hotel room key or old credit card (or a single edge razor blade to scrape the spot off the glass.

    Have you tried the nail polish removers (acetone and the ones for the fake nails) on a cotton pad?
