Clean an LED TV screen by turning it off, dusting it gently with a dry microfiber cloth, rubbing it clean using a vinegar-water solution, and buffing the television dry with a clean microfiber cloth. Avoid using harsh chemicals or rough materials, like paper towels or tissues.
Steps to Clean an LED TV Screen Correctly
Turn the TV off
Switch the LED TV off before you start cleaning it. It is easier to see dust and spots on a dark television screen.
Dust the screen
Rub the screen very gently with a dry microfiber cloth to remove all dust. Use only the minimum amount of pressure necessary to remove the dust. LED screens scratch easily, and portions of the screen may burn out if you apply too much pressure.
Rub the screen with a vinegar-water solution
Dampen the microfiber cloth with a mixture containing equal parts of distilled water and distilled white vinegar. The vinegar keeps the water from streaking as it dries. Gently rub the screen in a circular motion to remove all spots, and avoid vigorous scrubbing. Do not over wet the screen, and pay close attention to the edges of the screen to make sure liquid does not seep into the TV.
Dry the screen
Thoroughly dry the screen with a clean, dry microfiber cloth.
