Q: I have a new LCD television, and I'm not sure how to clean it. With my old tube set, I just spritzed it with Windex, but the surface of my new TV isn't glass.
A: "We recommend using LCD cleanser that can be purchased at any electronics store," says a customer service tech for Westinghouse, a manufacturer of popular LCD televisions. The cleaner can be found in both spray and wipe form. But what exactly goes into these LCD solutions?
Kai Hui of MG Chemicals, makers of one of many available LCD cleaners, explains, "The main ingredient in most wipes on the market is water. There needs to be a small percentage of isopropyl alcohol (IPA) to help get rid of the grease from busy fingers." Some LCD cleaning solutions may include up to 50 percent IPA, according to Hui, but any more than that could damage the screens.
Since I'd never suggest you spend more money than you have to, I'd start with a clean, soft cloth and regular ol' tap water. You can add just a capful of isopropyl alcohol to a glass of water if you need something to help loosen the greasy gunk on the screen, so it can wipe off more easily. Get the cloth damp and then apply to the screen instead of splashing the screen and trying to wipe up the liquid; and always — always — use a clean cloth, as tiny, hard particles trapped in the fibers can scratch the surface of your screen.
