Instructions for cleaning a computer monitor vary by monitor type, as cathode ray tube (CRT) and liquid crystal (LCD) monitors have different tolerance levels for handling techniques and cleaning agents. If you’re not sure what type of monitor you have, LCD monitors are typically very thin and flat, and CRT monitors are large and bulky. Also, a CRT monitor has an obvious glass panel on the front, while an LCD monitor has an almost gel-like appearance, though you should never touch it with your bare hands. If you have a laptop, it will have an LCD monitor. If your monitor came with an owner’s manual, always follow the instructions listed there for cleaning it, rather than a generic guide, as failure to follow the manufacturer’s instructions could void your warranty.
An LCD monitor.
To clean a computer monitor that uses CRT technology, start by turning it off and completely disconnecting it from the power source and from the computer. Then use an anti-static cloth or a very soft clean cloth to remove any dust on the surface. Then, spray a small amount of monitor or electronic device cleaning fluid onto the cloth and rub it steadily in one direction; top to bottom is a common choice. When you’re done, use a dry cloth to dry the monitor immediately. Never spray cleaning fluid directly on the monitor as it can damage the monitor and other computer components.
CRT monitors should only be cleaned when they are turned off.
If you have an LCD monitor, the cleaning process is slightly different because the screen is more fragile. As with a CRT monitor, you must turn off and completely unplug the LCD monitor before cleaning it. Start with an anti-static or very soft cloth and gently wipe any dust off the surface of the monitor. Next, put a solution of isopropyl alcohol or cider vinegar and water on a cloth and wipe the monitor, always moving in the same direction, then gently dry.
A little vinegar on a soft cloth is usually a safe way to clean a computer screen.
Some people have plasma screens, which are similar in some ways to LCD screens. To clean a computer monitor that uses gas or plasma, follow the instructions for cleaning an LCD monitor, but use a special liquid designed for that type of monitor instead of alcohol. When cleaning an LCD or plasma monitor, be sure not to use abrasive cleaning fluids, such as those containing ammonia, as these can damage the screen, causing it to become brittle, yellow, or crack in extreme cases. Avoid touching both types of monitors with anything, as they are very delicate and can break or dent.
If there are children in your home, it’s best to clean the monitor every three to six months, possibly longer if it’s clearly dirty.
If you clean your computer monitor regularly, you’ll find that your overall computer experience is more enjoyable, since you won’t be forced to search for scratches and dust on the screen. You can also clean other components, such as the case and keyboard, at the same time, removing pet hair, dust, dirt, accumulated food particles, and other debris. Depending on the number of animals and children in your home, you should clean your monitor every three to six months, or whenever it is obviously dirty.
Alcohol and water can be used to clean computer monitors.
