She recommends using a microfiber or soft cloth to gently dust the entire screen. If needed, flip the cloth over (or get a second cloth) in order to completely remove all dust, pet hair, and other loose debris. You can use a microfiber cloth to wipe down the speakers and cords as well. Use screen-safe cleaner.
Start With a Dry, Soft Cloth
(Some TV manufacturers will include a cloth for this purpose.) “Gently wipe the screen with a dry cloth to remove dust and other debris, but don't press too hard.” You may also want to wipe down the TV's cabinet and make sure dust isn't clogging the vents that help dissipate heat.
How Often to Clean a Flat-Screen TV. Clean a flat-screen TV once a week to wipe away the inevitable smudge marks, dust, and fingerprints that will accumulate. Giving it a regular wipe down will prevent dirt and oil from building up.
Not only does dust and dirt cause imagery to look bad, but dust can get inside and cause TV screen failure as well.
The glass screen of a TV set is electrically charged, so it attracts the dust particles.
TV screens: A quick primer
Windex is a no-no, unless you've got an antique TV with a glass display. You'll also want to make sure you don't spray liquid directly on your TV. Doing so can damage its display or even cause an electric fire.
You should never use baby wipes on a TV screen – however easy to grab and apply they might seem. 'Baby wipes are meant to be used on a baby, moisturizing and sometimes with oils – the last thing you want to apply to your TV screen,' says Tricia Holderman.
If you try to clean your TV screen with a baby wipe, it will leave behind streaks and cause tiny scratches. Instead, stick to water and a lint-free cloth.
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.
Turn the TV off and let it cool down for a few minutes before unplugging it. To clean the frame and screen, gently wipe it with a microfiber cleaning cloth. Make sure to wipe the TV frame and screen as gently as possible. TV screens are fragile and can be damaged when pressed too hard.
If your screen still looks dingy, make a 1:1 solution with water and white vinegar. In a spray bottle, mix equal parts distilled water and white vinegar. Spray the mixture onto a microfiber cloth, then gently wipe it along your TV screen. White vinegar is a natural cleaning solution that's effective but gentle.
Dust with a microfiber cleaning cloth. Use an ammonia-free electronics cleaning wipe or lightly dampen a clean cloth with water and wipe from top to bottom in an S pattern.
You could also use screen cleaning wipes. Never use traditional cleaning products to remove dirt from your TV screen. Use the same microfibre cloth you used for the screen to clean the buttons, bezels and back of the TV.
Avoid using toilet paper, paper towels, tissue paper, or etc. to wipe the screen. These materials can scratch the display and these scratch marks are not repairable. Avoid using strong cleaning products that contain ammonia, ethyl alcohol, toluene, paint solvents, acetone or ethyl acetate to clean the display.
In most cases, you can use either LCD screen cleaning wipes or spray a tiny amount of special cleaning solution onto a fine microfibre cloth, gently wiping the screen in circular motions until the screen is clean and dry.
For general cleaning of the frame and screen of your TV, you should use a soft, clean, lint-free, dry cloth. We recommend using a microfibre cloth. You should never use any type of window cleaner, soap, scouring powder, or any cleanser with solvents such as alcohol, benzene, ammonia, or paint thinner.
To clean fingerprints and greasy smudges off your TV screen, use a small amount of water or Isopropyl alcohol and gently rub the screen with a clean, soft, dry cloth.
Never Press Down on an LCD or LED Screen

Turn off your device and unplug it. Remove dust with a dry microfiber cloth. To clean spots and streaks on the surface of the screen, mist an LCD cleaning spray onto a dust-free side of your microfiber cloth; an easy DIY solution is 1:1 parts of white vinegar and distilled water.
You don't have enough ventilation.
But if your filter is dirty or clogged up with pet dander, dirt, or other air pollutants, it won't do a good job of collecting new dust that pops up—which would end up settling on your bedroom's surfaces. The fix is simple: Change the air filter.
Wash screens and frames with a solution of warm water and dish detergent. (A mixture of one part vinegar to three parts water will also do the trick.) With a soft-bristled brush, scrub both sides of the screen. Rinse screens again to remove soap film and any stubborn particles.
Suck up dust and lint with a vacuum attachment. Your television's vents help the TV stay cool and work properly. You can go over them with a duster, but it's smart to also vacuum with a soft brush attachment at least once a month. Many vacuum cleaners come with them included, but you can also find one on Amazon.
Some common activities that can cause physical damage are: Finger pressure when trying to move or turn the television. Spraying liquid cleaner on the screen, which can enter between the screen layers. Slight flexing or bending of the panel when trying to move it.
