7.3 Cleaning the Screen, Mirror
The screen is glass and fingerprints show up on it. Most of these may not show in the picture, but a
clean screen is better.
! The outer layer of the screen is glass. Don’t lean on it.
Don’t let it get scratched. Protect it.
WARNING
Spray the cleaner on the cloth. Never spray
anything on the screen. Do not let any liquid
drip down the screen. It will wick up between
the screen layers. When liquid gets between
the screens, it is impossible to remove. The
screen may be permanently ruined.
Why is the screen ruined?
The screen is made of several layers. The outer
layer is glass, but there are inner layers of acrylic that
are Fresnel lenses. If liquid runs down the screen, col-
lects at the bottom and wicks up between these lay-
ers, it is impossible to get it out.
Cleaners to use
Claire #50 Glass Cleaner is good glass cleaner. It
is a foaming spray in a pressurized can. It is sold
under many different names by local companies that
sell janitor and building maintenance supplies.
In some parts of the world this same cleaner is
known as Sprayway #50 Glass Cleaner. Ask at a jan-
itor supply company for either of these cleaners.
Hundreds of supply companies sell this product
under their own brand name.
Glass Wax™ does a good job of cleaning the screen.
It is a thick, pink liquid. Put some on a clean, damp
cloth and or a clean, damp sponge and spread it
thinly on the screen. Let it dry. Wipe up the powder
with a clean, dry cloth.
Cleaners NOT to use
• Do not use any cleaner that has an abrasive mate-
rial, such as sink and porcelain cleaners, or clean-
ing compounds that contain pumice. These
damage the anti-reflective coating.
• Do not use alcohol on the screen, unless you use it
in very small, very controlled areas not near the
edge. Alcohol will dissolve some of the material of
the black glass screen, if it gets behind it, and
make it useless. The only way to fix this is to buy
a new screen
• Do not use a ‘clean’ cloth that has been used to
wipe something else, such as a table. There could
be microscopic particles of grit in the cloth, and
these will scratch the screen.
• Do not use a sponge that has been used to clean
other things. It is very difficult to get grit out of a
sponge, once it is in there. Buy a new sponge, and
keep it for this purpose only.
Using soapy water
You can use plain soapy water to clean the screen.
Use a mild liquid soap, very dilute. Wring out or
squeeze out most of the water. (Read the Cautions on
this page.) Wipe carefully with the damp cloth. Dry
with a second cloth.
! White cloth is actually a better for wiping than colored
cloth. The dyes in cloth tend to make it less absorbent.
Same cleaner for mirrors, lens
You may use the same cleaner for the large mirror
and the lens. However, in most instances, the mirror
and lens only have dust. It is best to blow this away
using clean air. Clean, compressed air is available in
pressurized cans from stores that sell cameras.
Camera stores also sell lens cleaning solutions,
and this is good for the lens, mirror, or screen.
