An LCD screen provides clear, crisp visuals, but smoke film from cigarettes can obscure your viewing pleasure. As cigarette smoke settles on surfaces, it leaves a greasy film behind. Over time, as the smoke film accumulates, the LCD screen may appear dark and hazy. Removing the cigarette smoke from the screen requires using a cleaning agent that cuts through the film, allowing it to be wiped away.
Fill a spray bottle halfway with water and the other half with 50-percent isopropyl alcohol. Place the nozzle on the bottle and shake it to mix the liquids.
Spray a microfiber cloth with the alcohol solution. Starting at the top the LCD screen, begin wiping the cigarette smoke from the surface. Use gentle pressure only as you wipe the screen.
Wipe the cloth back and forth over the screen. Fold the cloth and respray it with the alcohol mixture. Continue wiping the screen, removing all the smoke film. You may need to refold the cloth and respray it several times to remove all the film from the LCD screen.
