how do I get my #$%@##$%^% windows clean?

Along the lines of what dustermaniac said, there is a product that my dad found called Novus. It's a polishing liquid for plastics mainly I think by market, but I used it on my glass with a razor blade to get off all the overspray the previous owner had from the paint job. I'm pretty happy with the results, they feel pretty dang slick when I wipe them off now.
