Developing a preventive maintenance plan for your PC will reduce
incidents of repairing or replacing parts.

mouse is especially vulnerable to dust and debris which are carried
from the mouse pad into the mouse ball and rollers. When enough dust
has accumulated, the mouse cursor hesitates or refuses to move
Has a rubber or metal ball on its underside this is what makes
it move via the sensors inside. Do not use harsh solvents inside the
mouse or on the ball. Chemicals can easily melt the plastic and
result in permanent damage to the mouse.
mouse ball: remove retaining ring cover (on bottom of mouse)
that holds the mouse ball in place
mouse ball: wash mouse ball in warm, soapy water; then dry it
thoroughly with a clean lint-free towel
Blow out the
dust: use can of compressed air to blow out any dust or debris
that has accumulated inside mouse
rollers: (3 rollers) use a cotton swab dipped in isopropyl
alcohol to clean off any layers of "gunk" that might have
accumulated on rollers Be sure to scrape the plastic shafts to
remove the caked on body oil mixed with dust. This must be
and Test: allow everything to dry completely; replace the ball
and retaining ring. Test to see if mouse is performing properly
Uses a laser to detect the mouse's movement. Optical mice have no
mechanical moving parts. They respond more quickly and precisely
than mechanical and optomechanical mice, but they are also more
expensive. There is no need to clean an optical/laser mouse because
there are no moving parts to collect debris. You may want to wipe
the four corners of the bottom of the mouse.
Keyboards are open to the environment so dust and debris readily
settle between the keys. Over time, these accumulations can jam keys
or cause repeated keystrokes.
long, thin nozzle to a can of compressed air and use the air to
blow through the horizontal gaps between key rows.
Use a clean
cloth dampened with alcohol to remove dirt or stains from the
keys and keyboard housing
Monitors rely on vent openings for proper cooling. Vent openings can
be blocked by paper or other objects. This will restrict ventilation
and force the monitor to run hot.
Use a air
compressor at 120lbs of pressure (canned air is not strong
enough) aim air nozzle on one side of the air vents to blow to
remove any accumulations of dust and debris from the vents
underneath the case as well as those on top of the case.
Use a clean
cloth, lightly dampened with alcohol or a cleaning solution
designed for computers to clean the monitor's plastic case.
water with mild soap to clean the CRT face.
Do not use
ammonia or any chemicals to clean flat screen monitors. They are
often treated with anti-glare and other coatings and even mild
chemicals can react with some coatings.
Read/write heads of the floppy drive touch the floppy disk. This
contact transfers some of the magnetic oxides from the floppy disk
to the drive's heads. Eventually enough oxides can accumulate on the
heads to cause reading or writing problems with the floppy drive.
The floppy drive should periodically be cleaned to remove any excess
Floppy drives can be cleaned either by using a pre-packaged cleaning
kit or by using a swab with isopropyl alcohol to clean the
ejecting and closing the tray, the motion should be smooth without
any hesitation or grinding. Accumulations of dust, pet hair, or
other debris in the tray may interfere with a CD.
While the tray is open, check for any accumulation of debris. Clean
the tray with a cloth lightly dampened with water only. Be sure that
the tray is completely dry before closing it again.
Some types of preventive maintenance need to be performed more often
than others. The frequency of preventative maintenance depends on
the nature of the activity.
In order for preventive maintenance to be useful, you have to
remember to do it. Something that can help is to create a preventive
maintenance schedule. Or you can give Gal Tec Incorporated a call
and we can put you on a schedule for a quarterly maintenance and
