Cleaning an LCD Screen
I found this information on a web site, so that must mean it's good advice!
You can purchase screen-cleaning kits at computer supply stores or your local electronics outlet, but they are expensive and the stores aren't always convenient.
Here is a really inexpensive and simple suggestion. All you need are four items:
Spray bottle
Distilled water
White vinegar or isopropyl (rubbing) alcohol
Clean, soft cloth
Mix the distilled water and the vinegar or alcohol. (Never use tap water. Tap water has minerals in it that will leave streaks.) The best ratio is 1:1, which would be like a half-cup of distilled water and a half-cup of vinegar or alcohol. Put the mixture into the spray bottle.
Make sure the LCD screen or television is turned off. It is much easier to see the dirt with the screen turned off.
Spray the mixture onto the soft clean cloth. Never spray the mixture directly onto the screen. The screen is delicate and that much force could damage the screen. Now gently wipe the screen with the dampened cloth. Start at the top of the screen, and very gently make your way down the screen. Let your screen dry before turning it back on. This will only be a few seconds.
A couple of hints that will help keep your screen lasting longer:
Remember not to touch the screen with your fingers or hands. The oil and dirt from your hands can damage the screen by burning the pixels out. Just like your mother used to tell you, keep your hands to yourself.
If all you need is a quick dusting of the LCD screen, try using anti-static and anti-cling sheets that are used for the dryer. They are great for removing the dust without damaging the screen.
