Instead of using circular motions for cleaning, however, it will be necessary to use a left-to-right motion to better protect the projector screen's delicate lenticular coating. Screen manufacturers also recommend starting out with dry cleaning using a microfiber cloth and ramping up with distilled water and soap solutions as needed based on the severity of the smudge. If you do, you can scratch the screen or strip the anti-glare coating off the screen and cause permanent damage. Make sure you try it on a part of the screen that is off to the side to see if it will damage it. If you were wondering if the above techniques can be applied to cleaning projector screens, the answer is yes – with some caveats. Important: Never use any type of window cleaner, soap, scouring powder, wax, or any cleanser with solvents such as alcohol, benzene, ammonia, or acetone. The best way to get a stain off of a projector screen would be to use Mr Clean Magic Eraser. And for the TV’s input connections, it’s best to use compressed air, making short blasts over the connections to remove any dust buildup. Other, less sensitive components of a TV like the stand and rear panel can be cleaned using pre-packaged dry dusting cloths. Also, never substitute paper towels for microfiber cloths since paper products can scratch the screen's coating, and the same goes for pre-packaged dry dusting cloths, which may contain oils that can leave permanent smudges.
Aside from avoiding strong household cleaners containing ingredients like alcohol and ammonia, the next most important rule to follow when cleaning your TV’s screen is to never spray liquid directly onto the screen’s surface.
