Unlike a computer monitor, the LCD or flat-panel display is not glass and requires special cleaning procedures.
When cleaning the LCD screen it is important to remember to not spray any liquids onto the LCD directly, press gently while cleaning, and do not use a paper towel since it scratches the LCD.
To clean the LCD screen use a non-rugged microfiber cloth, soft cotton cloth, or Swiffer duster. If a dry cloth does not completely clean the screen, you can apply rubbing alcohol to the cloth and wipe the screen with a damp cloth. Rubbing alcohol is used to clean the LCD before it leaves the factory.
