Answer:
As LCD screens are not made of glass, do not use regular glass cleaners to clean the screen. Instead, use a soft, microfiber cloth to gently remove visible particles on the screen (it's advised to turn the TV off before cleaning). Use a solution made for LCD, or in a pinch, create a solution using half distilled water and half isopropyl alcohol, for cleaning. Spray the solution on the cloth and gently clean the screen using circular motions. Avoid touching the screen with your fingers as that will leave oils that will attract more dust.
