How to Clean a Laptop Screen
Even at the tidiest of desks, a laptop screen attracts dirt and dust particles that are sure to fog up your screen. Enjoy your high-resolution laptop to the fullest by cleaning it every once in a while. While the LCD and LED screens on laptop computers are made of layers of delicate plastics and coatings, it's actually pretty easy to keep them clean without damaging the surface.
What you'll need:
Step 1: Turn off your computer.
Before doing any cleaning, it’s always smart to completely turn off and unplug your computer. When you're done, wait for any moisture from water or cleaners used to fully dry before you turn your PC back on.
Step 2: Dust the screen softly.
It's important to get any large dirt particles off the surface so that they aren't pulled along the screen, potentially scratching it, when you wipe it with the cloth. Very gently dusting the screen will remove these particles. It's important not to use paper towels, tissues or other potentially abrasive materials.
Step 3: Mist or lightly wet the cleaning cloth.
Be sure to use distilled water, as tap water can leave filmy mineral deposits on the screen. If you don't use a spray bottle, be sure to only lightly dampen the soft cleaning cloth. You don't want the cloth to be so wet that it drips or leaves behind moisture on the surface, where it could run under the surrounding plastic bezel. If water gets in this space, it could damage important electrical components.
Step 4: Wipe the screen gently.
Use wide side-to-side or top-to-bottom movements instead of small buffing motions to avoid leaving streaks or small scratches. You only need enough pressure to keep the cloth touching the screen. LCD screens are extremely sensitive and can develop discolored or dark zones if too much pressure is applied.
If a fingerprint or mark isn't coming off, don't press harder on it. Instead, use a 50/50 mixture of white vinegar and distilled water, again lightly wetting a soft cloth with the solution. It will be safe for the screen material but dissolve stuck-on dirt better.
