Use Stoner's Invisible Glass or Meg's NXT Glass Cleaner I suggest using a Waffle Weave glass towel you can get them from autogeek.com

On the outside windows use a up and down motion only and on the inside use a left to right motion. Or visa versa. That way you can tell which areas you are missing. Also flip the towel often once a side gets wet use it only on the first few swipes to get thing clean then flip to a dry side for final wipe.

You can also use newspaper to clean the windows as it doesn't shed. It is kind of a pain in the butt thought as it doesn't soak up much of the solution.

SlinkyBMX, I feel your pain. I've tried a lot of different products with little luck. I'll try the microfiber towel with the last product that seemed the lesser of the evils but I'm about to resort to using thegrease and wax removerthat I used on the glass and body to install my louvers and side scoops. It's driving me nutz, too. [:@]
