Remember when your computer LCD display had that brand-new, fresh out-of-the-box shine? If it's looking a little dull lately, it might be time to give it a good cleaning. Here's how:

Step 1: Disconnect the power cord from desktop monitors. For laptop displays, turn the laptop off, unplug the power cord, and remove the battery.

Step 2: Gently wipe the dust from the surface of the display using a dry, lint-free cloth, like a microfiber cloth. Remove any tags that may be on the cloth to avoid scratching the display with the tags.

Step 3: For tough spots, lightly dampen a microfiber cloth with water and gently wipe the display with as little pressure as possible.

If you prefer, you can use a cleanser made specifically for cleaning LCD displays, but do not spray it directly onto the display. Spray a small amount of the cleaner onto a microfiber cloth first, to avoid getting any cleaning solution inside the display.

Do not use any products with the following agents:

  • ammonia
  • ethyl alcohol
  • acetone
  • ethyl acid
  • methyl chloride

Those cleaning agents will damage the finish and any special coatings that may be on the display.
