Okay everyone, detailing the car today, I used this stuff called "Hope's Perfect Glass..." It comes in a black spray bottle and is seen at Linen's and Things and Bed, Bath and Beyond. I've also seen it online, just do a search. THIS STUFF IS THE BEST GLASS CLEANER I'VE EVER SEEN. I hope you all try it! No streaks, and you can use just paper towels... AWSOME!
