At first, you should look up the advice given on the respective manufacturer's homepage or in the manual.
From our point of view it is best to clean the monitor with a special cleaning agent called RONOL Screenclean. We have thoroughly tested the product.
It is best to use a dry and soft cloth (i.e. the ones for glasses). Please mind the fact that the monitor surface is very sensitive and can easily show scratches.
Additionally, most flat panel displays are sealed with an anti reflexive coating which can also be easily damaged by being handled improperly (for instance scraping of impurities by pencil, finger or screw driver, or aggressive cleaning agent etc.). Because dust particles can cause scratches during the cleaning process, too, it should be noted that the applied pressure should not be too strong.
In no case whatsoever should you use any kind of solvents like methylated spirits, gasoline, acetone, ethyl alcohol (= conventional alcohol). In case of doubt contact the manufacturer or your vendor.
Pull the power plug prior to cleaning and turn the LCD monitor off.
1. spray the cleaning agent n a cloth
2. Clean the monitor carefully with the moistened cloth
Please remove the power cable from the power supply by pulling the connector from the power outlet.
When the monitor shows a lot of impurities, clean it with a moistened cloth. Use warm water only and rub the monitor dry afterwards. Solvents or other aggressive cleaning agents can damage the casing surface. For the screen itself, it is best to use a soft cloth only, because otherwise the LCD coating could take damage.
If there is not much to clean anyway, you can just use a dry, soft and antistatic cloth.
The front side of the LCD screen is very sensitive. For this reason, avoid any kind of pressure onto the display screen (finger, pen etc.) and handle it with especially much care when you transport the device so it won't be subjected to any impacts or scratches (be sure to always use the original packaging cardboard for transport.
In order to make the monitor always look like in mint condition and to prolong its service life, we recommend a regular cleaning. Clean the casing and the LCD surface as described below:
Never use thinner, benzene, alcohol (ethyl alcohol, methyl alcohol or isopropyl alcohol), abrasive or other strong solvents because they can cause damages on the casing and the LCD display.
Remove smudges by wiping the casing with a soft cloth which you have moistened with a non aggressive cleaning agent beforehand. By any means don't directly spray wax or cleaning agents onto the casing (exact details can be found in the manual).
If needed, the actual screen surface can be cleaned with a soft cloth (for instance a cotton cloth or such that are used for cleaning glasses)..
Persistent smudges can usually be removed by moistening the cloth with some water to enhance the cleaning power.
Pull the power plug before you clean the monitor.
The interior of the casing may only be cleaned by service technician.
Don't use any abrasives and synthetic material dissolving cleaning agents. Don't let any liquid enter into the interior of the device.
Make sure to avoid the ventilation slots at the monitor.
Clean the LCD monitor's pressure and scratch sensitive display surface with a soft, slightly moistened cloth only.
A dry cloth is sufficient for cleaning the monitor's casing surface. If there are a lot of smudges, it is ok to use a moist cloth which has been dipped into water containing dish liquid and then wrung out well.
Your monitor has an anti-glare, anti-static screen coating. To prevent damage to the monitor screen's coating, use a regular household glass cleaner when cleaning the screen.
To clean the screen:
Switch the monitor off and remove the power plug (pull the plug, not the cable).
Soak a soft gauze cloth with isopropyl alcohol or ethyl alcohol and gently wipe the surface of the monitor. Avoid dusting it or wiping it with a cloth dampened with water.
Dry with a clean, soft cotton cloth.
CAUTION 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. Never use water to clean an LCD screen
The users guides for IBM Flatscreen TFT panels suggest the following: Caring for your IBM Monitor:
Be sure to turn off the power before you perform any maintenance on the monitor.
Clean your monitor as follows:
Gently wipe the covers and the screen with a soft cloth. Remove finger marks and grease with a damp cloth and mild detergent; do not use solvents or abrasives. Never apply detergent or other liquid directly to the screen. Dampen the cloth and then wipe. Never use flammable cleaning material to clean your IBM monitor or any other electrical apparatus.
Due to reasons of safety, be sure to always pull the power plug before cleaning the monitor. In case any liquid or non liquid material gets into the monitor during cleaning, please turn it off immediately, pull the power plug and then please inform your vendor.
Do not clean the screen surface with a coarse item. By no means should you use aggressive cleaning agents as the one listed below. These substances damage the screen surface and corrode the finish. [Editorial note: finish can most probably be described as the surface coating]. Thinner, abrasives, wax, cleaning benzine, spray cleaner, acids or leach.
Enduring contact between the casing and rubber or plastic products can corrode the finish.
Smudges can be removed using a moistened, soft cloth. For moistening, use a weak dilution of dish liquid and water.
We recommend regular cleaning of the display by means of a dry and soft cloth. Please don't use any paper towels since they could damage the LCD.
We recommend applying the spray cleaner "Tele-Wash". You can also use the cleaning cloths available from specialized dealers.
The cleaning methods generally don't differ from those that are common with conventional CRT monitors. NEC/ Mitsubishi especially recommends the special cleaning agent "Screen - Clean" sold by the Rogge company which was particularly designed for and tested with LCD monitors.
Excerpt from the manual of a Panasonic LCD monitor
Maintenance of the monitor:
Clean the monitor with a soft, dry cloth. If it is very unclean, wipe it with a cloth that you have dipped into a dilution of neutral cleaning agent and water and wrung out well beforehand. Then dry it with dry cloth. Using a chemically treated cloth or polishing cleaning agents can damage the surface or cause the color lacquer to come off. Don't rub the monitor with coarse or hard items and don't subject it to impacts.
The surface of the LCD monitors is covered with a protective coating. This coating is remains robust up to a certain hardness grade (about up to the hardness of a 2H pen). It is generally recommended not to subject the screen surface to any immoderate impacts or scratches. An optional protective cover can be purchased for every Philips LCD monitor. For normal cleaning, we recommend wiping the monitor with a clean, soft cloth. For more throrough cleaning, we recommend using products that contain isopropyl alcohol. You shouldn't use any products containing ethyl alcohol, acetone or hexane.
Pull the power plug out of the power outlet before cleaning the monitor.
For cleaning the LCD monitor, moisten a soft, clean cloth with some water or a non aggressive cleaning agent. If possible, use special cleaning cloths and respectively cleaning agents that have been designed to be used for the cleaning of antistatic coatings.
Use a cloth slightly moistened with a mild cleaning agent for cleaning the case of the monitor.
Never use inflammable cleaning agents to clean the flat panel monitor or other electric devise.
Make sure that the Viewpanel is turned off. Never spray or pour liquid directly onto the screen or the casing.
This is how you clean the monitor:
First wipe the screen with a clean, soft and non-fuzzing cloth. This way, dust and other particles are removed. If the screen is not clean yet, wipe it with a clean. Soft and non-fuzzing cloth onto which you have put some glass cleaning agent that does not contain any ammonia or alcohol.
This is how you clean the casing:
Use a soft, dry cloth. If the casing is not clean yet, wipe it with a clean. Soft and non-fuzzing cloth onto which you have put some glass cleaning agent that does not contain any ammonia or alcohol.
Viewsonic recommends not using any cleaning agents that are based on ammonia or alcohol. Some chemical cleaning agents can damage the screen and/ or the casing of the Viewpanel. Viewsonic can not be held liable for damages that have been caused by the use of cleaning agents that are based on ammonia or alcohol.
