Your laptop screen uses either a Light-Emitting Diode (LED) or Liquid Crystal Display (LCD), so properly drying it can protect its working condition. The best method is, of course, to avoid getting it wet. However, accidents happen. Apart from liquid spills, your plastic-covered screen needs to be cleaned and maintained to keep the appearance bright, and to avoid screen degradation and image discolouration. Watch out for such hazards as fingerprint smudges and food stains.

  1. 1

    Power down your laptop completely. Adding pressure onto a screen that is turned on could damage the hardware within the LCD or LED.

  2. 2

    Wipe with a dry microfiber cloth. To avoid streaks, use a left-to-right or up-and-down wiping motion.

  3. 3

    Air dry your screen. Although this may leave residue particles, it's better than using the wrong type (i.e. not a microfiber) of drying cloth.

  4. 4

    Spray the screen with compressed air to get rid of the dust particles left behind from cleaning. Although proper cleaning and drying will remove large streaks, fingerprints, dirt and grim, and small particles may still be attracted to your laptop screen.

Tips and warnings

  • Never close your laptop screen if it is wet. Moisture will enter your laptop, damaging or short circuiting the hardware.
