Perhaps the most important point to learn about cleaning flat screen TV's or computer monitors is what type of material you should and should not use to clean with. Never use anything remotely abrasive. Anything even slightly rough might scratch the screen, putting a huge damper on your TV-watching or computer-browsing enjoyment. Avoid everything from paper towels to tissues to newspaper.

If you have an expensive flat screen TV, it is worth investing in quality products with which to clean it. There are many special cleaning cloths and kits on the market that are electrostatic or treated with a substance that will help reduce glare, such as this flat screen cleaning kit available at Amazon.com.
However, if you have a small flat screen computer monitor or TV - and an even smaller budget - you may have something in your laundry basket or closet that will work great. Any soft cloth will work well for cleaning a small flat screen. For example, you could make use of that ever-expanding collection of mateless socks. A holey t-shirt or well-worn flannel shirt would work well, too. Aim for something soft, clean and lint-free.

There are also many liquid cleaning products on the market made especially for cleaning flat screen TV's or monitors, such as this alcohol-free formula by Monster. These cleaners work nicely and are worth buying if you have a nice new TV or the number of panels in your family's TVs, laptops, and monitors is adding up. However, if you need to clean a small spot on your flat screen monitor, plain distilled water will work beautifully most of the time, as will a combination of one part vinegar to one part distilled water.
Some products you should never use to clean a flat screen TV or computer monitor include tap water - the minerals in it can leave white spots on the flat screen; ammonia, ethyl alcohol or acetone - these chemicals can adversely react with the materials used to make a flat screen; or glass cleaner (which is mostly ammonia) - this can cause a yellowy tint, a filmy buildup or both.
