How to Clean an LCD Screen Release date: 2023-03-29 / Views: 38

Don't make the mistake of thinking that LCD screens work like your nifty new iPad. In general, touching should be off limits because pressing too hard on the screen can actually break or crack pixels. So the first rule to cleaning an LCD screen is don't do it unless you have to (i.e. unless it's actually dirty).


Rule No. 2: do it gently. Once you have those rules squared away, you need to know which cleaning materials to use and which to avoid.


Many retailers offer special cleaning solutions for LCD screens, but the truth is that most of these are made up primarily of water. So, if you don't want to take the time to go buy a cleaner or you want to save the money (maybe to put toward that "What Not to Wear" dress), you can just make your own LCD cleaner by mixing water with some vinegar or isopropyl alcohol -- the solution should be no more than 50/50.


You could even start with plain water and see if you need the vinegar or alcohol, which will come in handy when you're trying to wipe away greasy fingerprints. Some people recommend only using distilled water, but regular water works fine, according to Dave Chipman from Sharp.


Unless you want to end up with a melted, discolored, hazy or scratched LCD screen, steer clear of all spray cleaners. In particular, don't use any solvent cleaners that include acetone, ethyl alcohol, ethyl acid, ammonia or methyl chloride. You also want to avoid using any materials that could potentially scratch the screen's delicate surface. Opt for a soft, clean, cotton cloth instead of wood-based products like paper towels and tissues. Chipman suggests using a microfiber cloth for best results.


Now that you're armed with the proper cleaning supplies, you're ready to get down to cleaning technique.


You've mixed your cleaning solution and you have your microfiber cloth ready. All you need to do is apply the solution to the screen and swipe away, right? Actually, there's more to it than that.


An LCD screen is part of a complex electronic device, either a television or computer, and you don't want any of that solution running down the screen and into your keyboard, controls or other places where it could wreak havoc. To prevent this kind of accident, first make sure you turn off the screen. You have less chance of damaging the screen when it's off, and a black screen will help you to see the dirty spots more easily.


Once the screen is turned off, dip your cloth into the solution or spray it onto the cloth, taking care not to use so much that it drips. Use the cloth to apply the cleaning liquid to the screen with gentle strokes moving in one direction. Try to avoid haphazard strokes across the screen and instead work your way clockwise or counter-clockwise. For the sake of your screen's pixels, don't push too hard and don't try to rub out a particularly stubborn spot by applying more pressure. Just keep swiping the soft cloth across the screen, reapplying cleaning solution if you're having trouble.


In less than five minutes, you should have a pristine LCD screen ready to dish up your evening entertainment. Your eyes will thank you for making the extra effort.
