These coatings are extremely fragile, and any solvent designed to cut through the grime on glass can permanently damage or discolour a television screen.Liquid Getting Into the TV is Much Worse Than You ThinkThe main danger posed by applying a liquid directly onto the screen is obvious: liquid getting into places it shouldn't be. A television is not a solid block like glass; there are spaces around the edges and on the inside of the television that are home to important electronics like the display inverter.When liquid is applied directly onto the television screen, gravity takes over, and the liquid begins flowing downwards. The flow of the liquid can carry it down the sides of the television and into the electronics located on the inside. These electronics can be permanently damaged through short circuits, dead pixels, and corrosion, rendering the television unusable. It is unlikely that a manufacturer will cover liquid damage to the television under warranty, even if the television is brand new.How to Clean a TV Screen the Right WayStart dry. Turn off the TV and let it cool. A dark, cool screen is easier to see dust and smudges on, and cleaning a warm screen runs the risk of streaks and uneven spots. Remove the dust and dirt with a dry, ultra-soft microfibre cloth (the kind meant for glasses or camera lenses), gently rubbing in small circles.If the cloth isn't enough to remove a fingerprint or mark, dampen the cloth with distilled water to remove stubborn marks. Tap water has minerals that can leave spots, so it's best to use the purest water you can find. The cloth shouldn't be wet, only damp, so as not to streak the screen.Wipe in one direction, not back and forth. Don't press down hard on the screen, either, as this can push the liquid into the TV and cause permanent pressure spots, especially on OLED TVs. Finish by going over the now-dry spots with a dry region of the microfibre cloth to remove any excess moisture.
