- The number one caution: Don't use regular glass cleaner. Chemicals in window cleaner can permanently fog your screen over time and could even remove its antiglare coating.
- Customer service techs at Westinghouse recommend using LCD cleaner, which can be purchased at any electronics store. At MG Chemicals, makers of one widely used LCD cleaner, they say most cleaners are mainly water. If you don't have special cleaner on hand, use a glass of distilled water with a capful of isopropyl alcohol in it. Or use a mixture of equal parts of water and white vinegar. Avoid cleaning products that contain ammonia, ethyl alcohol, acetone, toluene, ethyl acid or methyl chloride. These could yellow the screen.
- Whatever cleaning agent you use, never spray it directly onto the screen. Put it on a cloth instead. Spray can get inside of flat panels and damage them. It can also run down, get into the TV circuits and short them out.
- Flat panel screens are made of plastic and scratch very easily. Some makers advise using microfiber cloths such as those recommended for cleaning laptop screens, eyeglasses or camera lenses. These are the best choices. Many cloths and tissues feel soft but are actually somewhat abrasive.
- Don't use paper towels. They can scratch the screen's surface. They can also carry a static charge which could damage the set's electronics, according to the Geek Squad.
How to Clean the Screen
- Turn the set off so you can see areas that are dusty or oily.
- Dust the screen very gently. If there is dirt or oil remaining, dampen the cloth with a cleaning agent and wipe gently again. Never press on the screen because it can cause pixels to burn out.
- The plastic edge of the screen can be cleaned with any multipurpose cleaner, but be careful so the cleaner doesn't contact with the screen itself.
