LCD (Liquid Crystal Display) Monitors have long replaced CRT (Cathode Ray Tube) Monitors as the predominant video output devices for desktop computers and laptops. These thin, flat-panel display appliances offer convenience and space efficiency at a very reasonable cost, making the LCD monitor desirable for both the manufacturer and consumer. This guide provides information on cleaning your LCD Screen.
How To Clean An LCD Monitor?
LCD screens are much more susceptible to streaking and picking up oils than older CRT units are. This is especially true with Laptops / Portables as the screen is transported from place to place and, when shut, can come in contact with a keyboard unit. While in contact, oils and residue left behind by your fingers on the keys can transfer onto the LCD screen and make it dirty. This process can happen every time you shut your laptop case. Luckily, however, cleaning an LCD monitor is an easy process that can be done anywhere at little or no expense. It is important to know what materials to use and the proper procedure though so that you don’t do more damage than good.
Firstly, an LCD screen is NOT a glass surface so traditional alcohol or ammonia based glass cleaners (ie- Windex) cannot be used. LCD screens are made of plastic and alcohol/ammonia can cause irreversible damage to them. Manufacturers have reported that such products can cause your screen to go cloudy/turn yellow, can make the surface material very brittle, and can cause surface cracks that can not be repaired. Instead of using a standard cleaner it is recommended to either use water or a mild glass solution that is ammonia and alcohol free. Alternatively, there are many LCD-specific cleaning products available today. Two such models are the Kensington Screen Guardian LCD Cleaner and the Meridrew’s KlearScreen Spray.
Before beginning to clean your screen it is important to turn it off first. After doing so, select a clean lint-free cloth material for wiping. It is important to select the softest cloth you can find to avoid scratching. Never use standard paper towels as they are too abrasive for the LCD surface and can cause damage. Also, always remember to dampen the cloth material with your cleaning solution and then apply the dampened cloth to the LCD screen. Spraying liquid directly onto the screen is NOT recommended.
How Can I Make My Own LCD Cleaning Solution?
The safest (non-commercial) LCD cleaning solution you can use to clean your monitor is water. Using water will assure that you are not applying dangerous chemicals to the LCD material. In some cases, however, water alone will not do the entire job or will leave parts of your screen unclean.
To create a safe LCD cleaning solution for yourself, simply dilute Isopropyl Alcohol down to 50% (or less) in water. Isopropyl Alcohol is the standard alcohol product that can be found in any drugstore – typically in solutions that are between 90-98% pure. To achieve the 50% level simply mix 1 part water for every part of Isopropyl Alcohol. Ie – 1 Cup of Alcohol / 1 Cup of Water.
