To best clean a big screen TV, we recommend following these steps:
Turn off and unplug the TV: This will prevent electric shock and damage to the screen.
Use a soft, microfiber cloth: Avoid abrasive materials like paper towels or tissues, as they can scratch the screen.
Gently wipe the screen in a circular motion: Start from the top and work your way down.
For stubborn smudges, use a slightly damp cloth: Do not spray liquid directly onto the screen.
Dry the screen immediately: Using a clean, dry and soft, microfiber cloth.
