When it comes to cleaning an LCD screen, there’s a right way and a wrong way. Let’s focus on the right way. For starters, turn your monitor off. In fact, to eliminate any risk of shock or electrical damage, unplug it. (Better safe than sorry). This cleaning will involve some moisture, and the last thing you want is for liquid to contact anything powered. Dampen a clean, soft cloth (a paper towel will do, but it isn’t the best choice) with water. Don’t soak it – just moisten it. And don’t use anything other than water. Ammonia- and alcohol-based cleaners can ruin an LCD. If plain water doesn’t do the job, make a 50/50 solution of distilled water and white vinegar. If you decide to use a spray bottle, don’t spray directly on the screen. Instead, spray the water or solution onto the cloth, and then wipe the screen. Use a circular motion, which is best for eliminating streaks, and apply only light pressure. Finally, let the screen air dry for a few minutes, or gently wipe it dry with a fresh cloth. Only when you’re absolutely certain it’s 100% dry, plug it back in and turn it on.
