What dissolves polyurethane off of glass?
This can happen on a wooden window, where polyurethane varnish on the frame gets on the glass. Unfortunately, once polyurethane cures, it won't dissolve in anything, which is one of the things that make it so good. If you want it off your glass, you've got to use a razor-blade scraper and scrape it off. You could try using acetone (or MEK, if you can get your hands on some). It won't actually dissolve the polyurethane, but it may soften it a bit and make mechanical removal easier.
