The techniques used for cleaning a laptop LCD screen, whether it’s for a desktop or laptop computer, are filled with controversy! Generally, no one recommends using any liquids because they can damage the LCD's delicate surface. Even so, you've gotta have something to rub with if you ever plan on getting that sneeze residue off the thing!
For general cleaning, get a soft, lint-free cloth.
Use it to wipe the dust off the monitor.
Dampen a sponge or lint-free cloth with water.
Be sure to wring out all the excess moisture. Rub the screen’s surface gently, and don't get any excess liquid on or inside the monitor.
Let the monitor dry completely before closing the lid!
Here are some other things to remember:
Often times, the keyboard creates "stains" on the screen. They’re hard to avoid and even harder to clean off. To help prevent the stains, consider storing the soft, lint-free cloth that you use to clean the monitor inside the laptop, between the keyboard and screen.
Office-supply stores carry special LCD screen cleaners as well as the lint-free wipes that you can use to clean your screen and the rest of your laptop.
One product that is recommended is Klear Screen, from Meridrew Enterprises (www.klearscreen.com). No, it's not cheap. You want good, not cheap.
Avoid using alcohol or ammonia-based cleaners on your laptop screen! They can damage the LCD screen.
Never squirt any cleaner directly on a laptop's screen.
