To clean smudges from the LCD screen, choose a non-abrasive cloth or towel. Turn off the computer and disconnect the power cable. Wipe the screen gently with a soft, dry cloth. If any marks remain, moisten the cloth with LCD cleaner, and then gently stroke the cloth across the display in one direction, moving from top to bottom.
Never spray or pour any liquid directly on the LCD screen.
Do not clean the screen while the system is on.
Some commercial window cleaners contain ammonia and are therefore unacceptable.
THE #1 REPAIR IS SCREENS!
