Read the warning labels on all your household cleaning products. Even glass cleaners might not be suitable for use on an HDTV screen, so check the manufacturer's warnings before you apply anything to the screen.
Keep chemical cleaners away from your HDTV on cleaning day. The harsh chemicals found in most common cleaning products will actually cause more harm than good.
Leave liquid cleaners under your sink when cleaning your HDTV screen. A liquid cleaner, whether it be water or a chemical cleaner, will drip down the screen and work its way into the interior of the TV, causing damage to your HDTV. You will be able to easily recognize when this happens, because your screen will develop smudges.
Use a cloth to clean the HDTV screen. Ideally, you should use a cloth that is recommended for HDTV screens, computer screens and other electronics. The word "microfiber" may be imprinted on the packaging.
Wet the microfiber cloth slightly. Just a hint of dampness is all you need. If water runs out of the cloth, then it's too wet and will cause smudges.
Develop a regular cleaning schedule for your HDTV screen. If you dust the screen daily, or at least several times a week, with your microfiber cloth, no other maintenance should be necessary. Not only will frequent cleanings make caring for your HDTV easier, but they will also enhance your viewing experience.
Prevent messes by asking family members and guests not to touch the television screen. You should also try to make sure children with sticky fingers do not come in contact with the screen.
Use a high-end cleaning product if you feel that regular dusting is not sufficient. Top-of-the-line television cleaning products are ideal for use on all HDTV screens, plasma screens, projectors and are safe to use around children and animals.
