Screen |
Never spray or squirt cleaner directly onto the screen. You should use a soft and moist cotton cloth instead and then rub throughout the screen. For a big chunky CRT with a glass screen(Cathode Ray Tube), you have to spray water or a mild window cleaning solution on a soft cloth . Take that cloth to wipe off your screen gently. For a flat panel LCD monitor (Liquid Crystal Display) remember that you have to use a soft dry cloth. If this does not completely remove the dirt and smear, use a soft cloth moistened with water to clean it . If you still need more cleaning, apply a little of isopropyl alcohol to the damp cleaning cloth. Avoid using paper towels on an LCD screen because they may scratch the screen.
