You know that gunk that mysteriously accumulates on the inside of your windshield? Anybody know what that stuff is? And you know how difficult it is to clean the inside of a windshield? I came up with a solution: use a Swiffer. The ball joint on the head of a Swiffer takes the wrist problem out of the equation, and the handle (use only the bottom half of the two-piece handle) takes the reach out of it. The keepers on the back of the Swiffer business end will hold a microfiber cloth just fine, so just spray the inside of the windshield and/or the microfiber cloth with your favorite glass cleaner and go at it. You can get into the corners and behind the rear view mirror, and you can comfortably clean that windshield until you're completely satisfied with the results. No charge for my friends.
