Hi, I'm Charles with ATX audio/video. Many people come and ask me how do you clean your plasma screen TV? First over I recommend not using any harsh chemical cleaners. The chemical cleaners will any household cleaners may breakdown the material in the screen much too fast and get lock in the trim bevel at the bottom of the screen. Over time the trim bevel will corrode. To clean the screen, I recommend using a micro fiber cloth and gently wiping the screen down. There's any heavy deposits on the screen I recommend using a light cleaner such as gloss cleaner. It will gently remove any smudges or fingerprints that may be on your TV screen. Also you might want to wipe down the trim bevel and check the back connects for dust or dirt. And that is how you clean a plasma screen TV.
