After spending a large amount of your hard earned money on a nice flat screen TV, the last thing you want to do is damage it or void the warranty. There is a proper method for cleaning dust, fingerprints and grime from your flat screen TV. Avoid most common cleaning products because they can damage the screen. Follow these steps to properly clean your TV.
Disconnect the power to your TV before you clean it each time. This is much safer and it will allow you to see the smudges and dirt better.
Choose either lukewarm water or a cleaning solution to clean your TV. Commercial cleaning kits that include both a cloth and cleaning solution are available. These cleaning solutions are specially formulated to clean flat screen TVs and monitors safely and are specifically labeled safe for "laptop screen" or "LCD screen." If you wish to use a solution, you must use one of these.
Dampen a soft cloth (preferably chamois, micro fiber or 100 percent cotton) with either the lukewarm water or cleaning solution. Just a gentle wiping of the screen is enough. Rubbing, scrubbing and hard pressure can damage the screen.
Dust your TV and its screen on a regular basis. Excessive dust can and will damage any electronic device.
Don't spray the cleaner on the screen. It can leak into the TV casing and damage the circuitry. Always apply the cleaner directly to the cloth in small amounts. Don't ever use strong chemical cleaners like alcohol, ammonia based cleaners, or window cleaners. They are not safe for usage on a flat screen TV. Don't use a paper towel or newspaper on your screen. These are wood products and will scratch the screen.
