A:Answer Hi SuperBrown, Good question. Before your start, please make sure to unplug the power cord from the wall outlet. We recommend cleaning the LCD screen with a soft, dry cloth. For more stubborn stains, you can use a soft cloth slightly dampened with a solution of mild soap and warm water. When you clean the screen, wipe it in small circular motions from top to bottom. Immediately afterward, use a soft cloth to dry the screen.
