i dont know if you want to try this, but someone showed me how to remove scratches on my old car's windshield using rubbing compound and a green scrub pad, then clean with windex. it worked fine on my car, but it might make your glass hazy so try it on a test piece somewhere else first.
I've heard of lots of people that use vinegar. As far as windex, why would you ever spray that IN your tank, as I am guessing thats where the scratches are.
