The monitor's glass screen is the component on a PC that should be cleaned the most often. The monitor screen produces a lot of static electricity that attracts and holds dust and flying lint. If the screen becomes covered with dust, it can strain your eyes to view the screen for extended periods.
Unfortunately, most people take too many safety chances when they clean the monitor screen. The following steps detail how you can safely keep the glass screen and the monitor itself clean and bright:
1. Before cleaning the monitor, switch its power off and unplug it from its power source. There is really no need to disconnect it from the PC. After turning the monitor off, wait a few minutes before beginning to clean it. Do not wear an ESD ground strap when working with a monitor, even to clean it.
2.Using compressed air, clean away any dust on the top of the monitor's case. Point the air stream to blow across the top of the monitor, not directly down on it, to prevent dust from blowing into the monitor's vents. Never open and remove the cover of a monitor! There is an extremely high voltage hazard inside every monitor, regardless of its size.
3.Use a soft cloth and either isopropyl alcohol or a general purpose no rinse cleaner to clean the outside of the monitor case. The alcohol is probably a better choice because it will not create a safety hazard if it's inadvertently dripped inside the case.
4. Use an antistatic cleaner or a Scotch Brite HPEC for electronics cloth to clean
the glass of the monitor. Never use an ammonia based glass cleaner on the
monitor glass. The monitor screen is coated with filtering chemicals to help
improve the image and reduce eyestrain. Using a harsh cleaner can remove
these coatings, harming the monitor and potentially harming you.
Never use water or a liquid cleaner to wash the monitor's glass with the
power on. Water is an excellent conductor of electricity and if your hand
makes sufficient contact with the screen you could be the ground for the
electricity in the monitor.
5.Reconnect the monitor and test the video. If nothing displays, check the power switch, the power cord, the video connection, and the brightness and contrast settings, any of which could have been accidentally dislodged, moved, or turned while you were cleaning the case.
