Desktop Services: Cleaning your Desktop Computer System

Clean LCD Monitor

  • Power off and unplug your monitor.  Make sure the monitor is not too hot before proceeding.
  • If your screen is dusty, use a clean, soft, lint-free cloth to wipe it gently.  Do not use a paper towel, as it may scratch the screen's surface.  Products are available in the Corporate Express catalog or almost any office supply store.
  • If your screen needs more than a dry wipe, use a solution that is 50% water, 50% isopropyl alcohol with a soft, lint-free cloth.  Alternatively, you may use cleaners that specifically state they can be used with LCD monitors.
  • Always moisten the cloth first and then wipe the LCD in one motion, from top to bottom.

Clean Keyboard, Mouse, and Case

  • Use compressed air to blow out any dust or debris from your keyboard.
  • Wipe down the plastic case of your computer with a damp cloth.
  • You may need to clean the ball of your mouse.  Turn your mouse over, twist off the cover in the direction indicated and take out the ball.  Clean the ball with a damp cloth.  Do the same with the track ball housing inside the mouse.  Then, put the mouse back together.
  • If your mouse is an optical mouse, first unplug the mouse from your computer. Then turn over the mouse and clean off any debris stuck to the bottom.  Next, clean the surface area on which your mouse moves.


  • Do NOT use cleaners, such as Windex, that contain ethyl alcohol, ammonia, acetone, ethyl acid or methyl chloride to clean your LCD/flat-panel monitor.
  • Do NOT spray cleaners directly on the display.
  • Do NOT touch or press the LCD screen with your fingers or any other objects.
  • Do NOT use paper towel to clean your LCD screen.
