While it is not necessary to turn the monitor off to clean it, this can be a good idea. When the monitor is off, you can see the smudges and dirt better, and you can be sure that you wonít burn out any electrical components if water or cleaning liquid is inadvertently dripped onto or into the monitor. By the way, if liquid is ever dripped onto a monitor, you should turn it off immediately and allow it to dry completely before turning it back on.
Those big chunky CRT monitors have glass screen which are easily cleaned. The important thing to remember is that you donít ever want to spray any liquid directly on the screen. Instead, spray the cloth with water or a mild window cleaning solution then wipe the screen. You can use the same damp cloth to clean the entire monitor case, as well. If you prefer, you can also use moistened paper towels to clean CRT monitors, You will be only cleaning the outside of the monitor case and screen. Never open the monitor casing which contain electric voltage that can cause a shock.
Flat Panel LCDs
LCD monitors are often called flat panel monitors because they are flat and thin. These are the types of screens that are used in most laptop computers, and they are also becoming very popular for desktop computers. LCD screens are softer than CRT glass screens, so they require some extra tender loving care. Keep your fingers and sharp objects away from these screens since they are susceptible to damage and scratches.
Use a soft dry cotton cloth to remove fingerprints and smudges from the screen. If this does not completely remove the dirt and splotches, use a small amount of isopropyl alcohol on the cleaning cloth that has been dampened with water. (A small amount of vinegar can be substituted for the isopropyl alcohol.) Again, spray the liquid on the cloth and never directly onto the screen. Do not use paper towels on an LCD screen as they can scratch the screen. Never use ammonia, ammonia-based cleaners, or strong cleaners which can cause the surface to yellow and become brittle.
It is good to have a special clean cloth that is dedicated to use on the LCD screen. Donít pick up any old rag, as dirt particles in the rag can scratch the surface of the screen. Special LCD cleaning cloths are available and can be an excellent investment.
The best cleaning method is to stroke the cloth across the display in one direction, moving from the top of the display to the bottom.
