3. First of all, it’s easier to see smudges and
stuff on a black screen, so turning off your
monitor makes it easier to see what you are
doing. It’s also safer for you and for your
computer: cleaning your monitor while its on
and the pixels are all fired up could damage
your screen or potentially give you an
unpleasant electrical jolt. So, turn it off!

4. If you’re going to clean your computer’s monitor, you might
as well clean the whole thing. Spray Windex or some other
gentle cleaning product onto a cloth and wipe the casing,
frame, and keyboard. Don’t spray directly onto the
computer though: you could accidentally get Windex on
your monitor, which would be bad. Windex is ammonia-
based, and ammonia (along with alcohol) can seriously
damage your screen by stripping it of anti-reflective
coating or by causing it to cloud up. Use a Q-tip to clean
spaces you can’t reach with the cloth.

5.  Do not use paper towels. Paper towels are meant to clean up spills
around the house–if you look at them super closely, they are fuzzy
and abrasive. They can mess up the finely crafted, delicate piece of
technology that is your computer’s monitor. So, use a clean cloth
instead. Do you wear glasses? If so, use the cloth that you get
whenever you go in for a new pair of glasses, known as a
MICROFIBER cloth. Buy some MICROFIBER CLOTH, which you
can get at Bed Bath & Beyond or any home-supply store. Microfiber
cloth won’t scratch your monitor and it won’t leave behind any lint
residue, so it’s perfect. Wipe the monitor with a dry cloth in broad,
straight strokes, pressing as lightly as possible. Then, dampen the
cloth with water and wipe again until all the smudges and grime are
gone.

6. If you have a stubbornly dirty monitor to deal with,
you can make your own cleaning solution by
mixing white vinegar and water in equal
proportions. This will be strong enough to get rid of
the worst of smudges but mild enough to not
damage the screen. Dampen a MICROFIBER cloth
with this homemade concoction and wipe as
normal. Again, do not use ammonia- or alcohol-
based cleaners!

7. Gently dry your monitor with a MICROFIBER
CLOTH or let nature do the work for you. To avoid
any moisture or electrical damage, make sure your
screen is completely dry before turning your
computer back on.

10. Shut down your computer. If you’re using a
wired desktop keyboard, unplug it.
Tilt the keyboard upside down and shake it
to remove any loose debris. If you have a can
of compressed air, you can spray it in
between the keys as well.

11.  Dip a cotton swab into some gentle isopropyl alcohol (rubbing alcohol) and brush it
in the area surrounding each key. You may need to use multiple swabs, depending
on the amount of dirt. If you’re unsure of the alcohol's strength, try it on a small,
inconspicuous area first to make sure that it doesn’t cause discoloration or remove
the lettering on the keys.
 Dip a cloth or towelette into the isopropyl alcohol, and brush it along the tops of
all the keys and surfaces, taking care to scrub heavily used areas (such as the
Enter key and spacebar) to remove buildup. For particularly dirty spots, you can
use a toothpick.
 Use a dry, lint-free cloth to remove dust and polish the keyboard.
 If you’re using a wired desktop keyboard, plug it back in.

12.  Most desktop keyboard letter keys are designed to allow you to
remove them with a blunt tool such as a butter knife or flathead
screwdriver. Simply place the tool under a corner of a key, and pry it
off. If you’re unsure of your particular model, or if you are using a
laptop, consult your device's manufacturer to learn whether key
removal is supported, so that you avoid damaging your keyboard.
 Once you've removed the letter keys, you can wash them
individually with water and soap, or alcohol, to remove dirt.
 After washing, dry the keys, and then place them on a towel to
continue drying.

13. With most of the keys removed, you should have better
access to the area underneath. Thoroughly blow out this
area with compressed air, or even a gentle vacuum.
Dip a cloth or towelette into isopropyl alcohol, and wipe it
along the inner surfaces.

14.  As soon as the keys are totally dry, pop them back into place. Each
key should snap back on with a small amount of pressure. If you
forget where each key goes, consult a keyboard map.
 Give everything one last wipe with a dry, lint-free cloth.
 If you’re using a wired desktop keyboard, plug it back in.

16. An optical mouse uses a light-emitting diode (LED) and an
optical sensor to navigate the pointer. If the pointer on the
screen does not move smoothly with the optical mouse, you
might need to clean the mouse. To clean the optical mouse,
follow these simple steps:

17.  Turn off your computer.
 Disconnect the mouse cable from the computer.
 Turn the mouse upside down to look at the lens.
 If there is a smudge on the lens, gently clean the area with a plain cotton-tipped swab.
 If there is debris in the lens, gently blow the debris away from the area.
 Check the surface on which you are using the mouse. If you have a very intricate picture or pattern
beneath the mouse it may be difficult for the digital signal processor (DSP) to determine changes in
the mouse position. Also, Mouse Pads get dirty and need to be replaced - it is recommended that you
replace your mouse pad every year.
 Reconnect the mouse cable to the computer.
 Turn your computer back on.

18. The non-optical mouse uses a ball to navigate the pointer.
To clean a non-optical mouse:

19.  Turn off your computer.
 Disconnect the mouse cable from the computer.
 Turn the mouse upside down. Twist the retainer ring to the unlocked
position to remove the ball.
 Place your hand over the retainer ring and ball , and then turn the
mouse right-side up, so that the retainer ring and ball fall out into
your hand.
 Wash the ball in warm, soapy water then dry it with a clean cloth.
 Blow air carefully into the ball cage to dislodge dust and lint.

20.  Look for a build up of dirt on the plastic rollers inside the ball cage. This build up
usually appears as a stripe running across the middle of the rollers.
 If the rollers are dirty, clean them by using a cotton swab soaked in isopropyl
(rubbing) alcohol. Turn the rollers with your finger and continue swabbing them
until all the dirt is removed. Be sure the rollers are still centered in their channels
after you clean them.
 Remove any fibers from the swab that might be remaining on the rollers.
 Replace the ball and the retainer ring. Twist the retainer ring to the locked
position.
 Reconnect the mouse cable to the computer.
 Turn your computer back on.

clean! =D
