Computer screens are magnets for sticky fingerprints, dust and smudges. Over time, these marks can be distracting as they blur type and images. To clean your monitor properly, follow these simple guidelines to ensure you can clearly see the display on your monitor.
If you have a glass monitor, a commercial glass cleaner is safe to use. Spray the cleaner onto a clean cloth, then wipe the monitor. Never spray a cleaner or other liquid near a computer, as the chemicals and fluid can drip into the keyboard and vents near the monitor.
Before you clean a glass monitor, unplug the computer. Spray the cleaner on a lint-free cloth, and wipe the screen.
LCD and Flat-Panel Monitors
Commercial cleaners contain ammonia and other chemicals that can permanently damage or strip the anti-glare material. If you have a LCD (liquid crystal display) monitor, never use a household cleaner or rubbing alcohol on the screen and don't use paper towels, as they can scratch the surface. Instead, us a soft cloth made of cotton or use a Swiffer cloth or duster.
Commercial cleaners designed specifically for LCD screens are available and are safe to use. With all monitors, after you have thoroughly cleaned the computer screen, dry it with a clean cotton cloth.
