Cleaning a liquid crystal display (LCD) screen sounds like it should be a fairly straightforward thing to do, however there are some things you should know about properly cleaning your LCD screen. For starters, and LCD screen is unlike the old fashioned television screens, and is not produced using glass. Therefore, some precautions must be observed when cleaning the display.
1) Purchase a proper cleaning solution/kit.
Though you may decide to skip this step, I suggest purchasing a proper LCD cleaning solution and/or kit. Many manufacturers have created specially formulated solutions for cleaning LCD display screens for desktop and laptop monitors. If you can find a kit, I would use that as it already has a soft cloth in it, as well as the solution. Depending on the manufacturer, I have found very desireable results from cleaning gummy/dusty LCD screens with a purchased product over a homemade cleaning solution. The manufacturers products also seem to have good evaporative properties, which ties in with not accidently getting the cleaning solution inside of the LCD unit.
2) Use a soft cloth.
It may sound like a simple step, but many people will just grab whatever they can find to clean the screen. Due to the material used for LCD screens, especially those that have a glossy (shiny) finish, cloth that is not soft may put abrasive marks onto your screen. This is very undesirable, and will greatly reduce the quality of images on your LCD screen.
3) Do not use a window cleaning solution!
Many people will tell you that they have used Windex to clean their LCD screens, and that they have never run into troubles with it. Windex, and other window cleaning solutions will eventually start to wreak your screen. Another reason not to use these types of solutions is that they are usually quite runny, and are made that way to cover large areas. This is not what we want for our LCD screens, as some of the liquid, if used alot, may seep into the edges of the screen, and cause distortion of colors on the screen, or short-circuit the electronic components.
4) Proper techniques for applying cleaning solution.
This bit is important because you will not want to have left over residue or streaks after you just cleaned your LCD screen! Lots of people have different techniques, however, the one that seems to work for me, when I cleaned the LCD screens at the computer store I worked at was to wipe in a circular motion. I’ve noticed that when some of the others cleaning wiped from left to right, or vertically, that it left some bad residue in corners and streaks that were very visible. If you wipe in a small circular motion, getting into the corners and going over the screen a couple times, you should have no residue left, and you will not notice streaks. It is exactly like buffing your car, or boots, etc. You do not need to apply alot of pressure, but you should make sure that you spend a good 3-5 minutes on your computer/laptop screen, and probably a bit more for larger LCD TV screens.
