Flat screen monitors such as those found on your new TV or computer are known as LCD monitors or high-definition flat-panel display. They're very different from the screens found on your old CRT or "tube" TV models. Those older models had thick glass which could easily be cleaned with window cleaner and a paper towel. Not so with an LCD or plasma screen. The LCD panel is made of specially designed flexible plastic and is very sensitive to chemicals. If you apply cleaners with chemicals in them, you may end up with a blank flat screen. Even using ordinary kitchen towels or paper towels may scratch the screen and leave lint.

As you can see, it's important to know how to clean your flat screen TV without causing damage. You can, of course, buy bottles of special cleaner, but why bother when you can make the solution yourself.

Here's how to clean a flat screen TV.

  1. Turn off the monitor. If the screen is dark it will be easier to see the dirty and oily areas.
  2. Use a dry, soft cloth -- the kind you would use to clean your eyeglasses -- and very gently wipe the screen. If this doesn't remove the oil or dirt, do not press down harder and try to remove the dirt. Pressing down on the screen will cause the pixels to burn out. Rather, proceed to the next step.
  3. Make a solution of equal parts water and vinegar. Dampen a cloth in the solution and gently wipe the screen. Again, rubbing and scrubbing will damage the screen.

Here are some important tips you should know.

  • Avoid using paper towels, toilet paper or something like your shirt to wipe the screen, as these may scratch or damage the screen.
  • Do not use products that contain ammonia, ethyl alcohol, acetone or ethyl chloride. These chemicals can cause the screen to turn yellow.
  • Never spray liquid directly on the screen as it can run inside the monitor and cause damage [sources: Best Stuff, Bright Hub].
