This is Why You Shouldn't Clean Your HDTV with Windex We know spring is here and we know you wanna keep all your gadgets nice and shiny, but you see that dark, u-shaped streak running through the bottom of this DLP TV? That's what happened when some poor schmo sprayed Windex (or any other cleaner) directly onto his flat-panel DLP. The liquid drips down to the bottom of the screen and then creeps back up, sandwiching itself between the screen and the protective plastic. Yeah, fingerprints and smudges happen, but use a soft cloth to wipe 'em away. Or yell at anyone that comes too close to your TV. (That's what I do.) Anybody out there have any other screen-cleaning tips?
