For Christmas my wife gave me some Armor All Glass Wipes in my stocking. I threw them in the Garage in my chemical cabinet and honestly forgot all about them. When I was cleaning the KJ last weekend, I found them again and used them for the first time.
All I can say is. Wow, these things are awesome. They remove the water marks from the glass quickly and absolutely leave no streaks. Another thing that I like is I'm not carrying around a roll of paper towels and a spray bottle of cleaner. Also you don't have to worry about over spray either when using the bottle.
