Keyboards take the most abuse of any of
the components that make up a computer system. They are also open to
the environment, which allows dust to build up on the circuit board
over time. Periodic cleaning of the keyboard will prolong the lifespan
and prevent malfunction. The keys on a keyboard can be removed, which
allows easy access to the areas where dust collects. A soft brush or
cotton swab can be used to remove dirt from below the keys. Use
compressed air to blow out dust from below the keys. However,
it is necessary to hold the keyboard vertically or in an inclined
position and blow the blasts of air across so the dirt and dust is
knocked off and out of the keyboard. Otherwise, larger dirt or dust
particles will come off and lodge at the interior corners or other
obstacles associated with the springs or foam material that controls
the keyboard keys.
