For television screens that are coated with a special treatment, you have to be careful of the cleaning products you use. To find out if your screen has been specially treated, check you owner’s manual. With this type of television, dilute a mild liquid dish soap with 100 times the amount of water. Soak a microfiber cloth in this mixture and then wring out any excess liquid so it doesn’t drip. Wipe this cloth across the screen and then follow with a dry cloth to remove any remaining water.

Start by gently wiping across your television and the screen with a soft, dry cloth. If there are smudges, then make a solution that’s half water and half rubbing alcohol. Dip the corner of a cotton cloth in the solution, squeeze out the excess liquid and carefully wipe down your tv screen, focusing on the smudges. Finish up by wiping everything again with a new soft, dry cloth.

When you’re cleaning something as fragile as a flat-screen television, you’re bound to notice (or even cause) a small scratch every once in awhile. If you end up with a scratch on your television screen, then you can repair it with petroleum jelly. Coat a cotton ball with petroleum jelly and very gently dab it onto the scratch.
