The surface of the LCD screen is much more fragile than the ordinary CRT monitor, so it is best to choose a special screen cleaning cloth and special cleaning agent. This screen cleaning cloth has good water absorption and good vacuuming power, dust will be easily absorbed on the cloth, and will not re-stick to the screen during repeated wiping, and will not cause dust particles to scratch the LCD screen.

To clean the oil stains and sweat stains on the LCD display, special cleaning agents can be used. Do not use general household cleaners and organic solvents such as alcohol, which will corrode the surface of the display. The most common low-end LCD monitor cleaner kits (cleaners, brushes, professional screen wipes) in the computer market cost only 5 yuan, while the kits from major computer manufacturers cost about 200 yuan, using water or vinegar, soft cloth, etc. DIY methods are also available.

However, it must be clear that no matter which method, you must not let any liquid enter the gap between the boundaries of the LCD display. There are many examples of display damage caused by liquid accidentally entering the gap. It is recommended that when cleaning, after the power supply and data cable are physically separated for 20 minutes, lay the monitor flat (to prevent liquid from flowing into the gap due to gravity), and after the screen cloth is slightly wet, pay attention to the boundary when wiping; The water is sprayed directly onto the screen (avoid liquid forming into the crevices). Once the liquid has evaporated, it can be used later.
