I never used those spray screen cleaners because you need a cleaning cloth for them to work. I would always lose those! The Monster CleanTouch Pen combines the screen cleaning solution and cleaning cloth in one pen-sized nub.
What better way to clean that dusty screen than rubbing it down with a cheeseburger? If a cheeseburger isn't your thing, how about a donut, piece of cake, cookies or a BLT?
