One of the most common questions I
am asked, now that LCDs are in wide use, is how to clean one. Every manufacturer has their recommended
method. What Envision recommends will ruin
an NEC LCD and void your warranty. As
you will be able to tell every LCD needs to be cleaned in a different way. Another thing I learned from finding all this
information is that every manufacturer has the same warning: Never touch or
press on the LCD screen with your fingers - NEVER!!! Doing so can cause the pixels to short out
and die. Then you will have blank spots
on your LCD.
Here is the cleaning information I
have gathered from various manufacturer's web sites. The text is taken verbatim from the
manufacturer’s web sites, “read-me” files, PDFs and
e-mails.
List of manufacturers:
I called CTX tech support and was
told the way to clean their LCDs was in the Technical
Glossary and General FAQ. I asked the
guy to check that out and he said he couldn’t find it either. He said to use very mild soap, tepid or
lukewarm water and a just slightly moist lint-free cloth. This is supposed to be added to their General
FAQ.
I received an e-mail in response to
a web based tech support request.

You should only touch the screen with a DAMP moist cloth and and VERY gently clean.

How do I maintain and clean the LCD screen on my Dell™ notebook?
Discussion Cleaning The following cleaners are acceptable:
The following cleaners are unacceptable:
NOTICE: These cleaners might cause permanent damage to the LCD due to a chemical reaction. Some commercial window cleaners contain ammonia and are generally unacceptable. Clean the computer's built-in LCD display with a soft, clean cloth and one of the cleaners listed above or a commercial window cleaner that does not contain ammonia, wax or abrasives. Apply the cleaner to the cloth, and then stroke the cloth across the display in one direction, moving from the top of the display to the bottom. If the display contains grease or some other contaminant, use a cloth with an acceptable cleaner listed above instead of a commercial window cleaner. |

Q. How do I clean my monitor - LCD
& CRT?
A. You can use Windex® to clean the
screen and 409® clean the outer casing of the monitor. Please use a
"soft" non-fibrous cloth to clean the screen. Do not use any paper
products to clean the screen.
[Webster:
I would use the non-ammonia based Windex]
Cleaning
your LCD monitor
Shut
down and unplug the computer and clean the LCD screen with a soft cloth moistened
only with water. Wet the cloth, wipe the display, and then dry the screen with
another soft cloth.
Caring for and Cleaning the Display
To maximize screen life and prevent damage
to the LCD panel, we recommend that you:
Ž Use the display power management
system (if available on your PC).
Ž If you don’t use a power management
system, turn off the display when you won’t be using it for an extended period.
Ž Don’t press, rub, or poke the
display with your finger or other object.
Ž Handle your display with care
Your LCD module is a high-quality
optical device that requires special care when cleaning.
To clean the screen:
1.
Shut
down the PC.
2.
Turn
off and unplug the display
3.
Gently
dust the screen with a dry, soft, line-free cloth. [Webster: I think they meant lint-free]
Note: If the screen is still dirty, you can dampen the cloth with several
drops of
distilled water. Make sure the
LCD panel is completely dry before you turn
the display back on.
4.
Plug
in the display.
5.
Turn
on your PC and display.
To clean the screen:
1.
Turn
off the monitor and remove the power plug (pull the plug, not the cable)
2.
Soak
a soft gauze cloth with isopropyl alcohol or ethyl alcohol diluted with water
(1:1) and gently wipe the surface of the monitor. Do not dust it or wipe it with a cloth
dampened with pure water.
3.
Dry
with a clean, soft cotton cloth.
CAUTION: Never use pure water to clean the LCD screen.
Do not use cleaning solutions containing fluoride, acids or alkalis. Do not use
ketone substances such as acetone or solvents such as xylene or toluene to clean
the monitor. Do not use benzene, thinner, ammonia or any volatile substance to
clean the monitor's screen or cabinet. These chemicals may damage the monitor.
This is the strangest one ever. On
I will assume he means rubbing or
isopropyl alcohol and a cotton lint-free cloth.
You are on your own for Hyundai LCDs it seems. Sorry
I couldn’t find anything more concrete for you.

KDS Technical Support,
From the User Manual for the RAD-5
page iii:
■ Cleaning
The display area is highly prone to
scratching. Do not use ketone-type
cleaners (i.e. acetone), ethyl alcohol, toluene, ethyl acid
or methyl
chloride to clean the panel.
Doing so may result in permanent
damage.
Water,
IPA (Iso Prophyl Alcohol)
and Hexane are safe cleaners.
Do not
allow oil or water to penetrate the display, as droplets cause
staining and discoloration with time.
Keep food
particles and fingerprints away from the display area at all
times.
MAG was another hard one to get any
information on. On

Clean the LCD monitor surface with a
lint-free, non-abrasive cloth. Avoid using any cleaning solution or glass
cleaner.
[Webster:
Sounds like you need to use lukewarm water with a very weak detergent, like
Palmolive. Don't lather the solution and
just barely moisten the cloth.]
Clean
the monitor with a soft, dry cloth.
CAUTION: Do not use benzene or thinner or rubbing alcohol. Doing so may adversely affect the surface,
e.g. discoloration. In addition, do not
use commercially-available cleaners and cosmetics as they may contain
components harmful to the surface.
Do not directly add or spray water
or detergent. If liquid enters the
inside, this may cause the display to work improperly or be damaged.
Unplug the monitor, if you need to
clean it with a slightly damp cloth. Wiping the screen with a dry
cloth is possible when the power is off.
However, never use alcohol, solvents, or ammonia-based
liquids.
Q: How should I clean the LCD surface?
A: For normal cleaning, use the clean, soft
and fine. For extensive cleaning, please use Isopropyl
alcohol. Do not use other solvents such as ethyl
alcohol, ethanol, acetone, hexane, etc.
Cleaning
LCD monitors:
Wipe
the screen with a clean, soft, lint-free cloth. This removes dust and other
particles.
If
still not clean, apply a small amount of non-ammonia, non-alcohol based glass
cleaner onto a clean, soft, lint-free cloth, and wipe the screen with only a
slight pressure. Too much pressure may damage the screen.
Warning: DO NOT use water on LCD
monitor.
Cleaning
monitor case:
Use
a soft, dry cloth.
If
still not clean, apply a small amount of a non-ammonia,
non-alcohol based, mild non-abrasive detergent onto a clean, soft, lint-free
cloth, then wipe the surface.
