LCD screen surface is much more fragile than ordinary CRT display. It is better to choose special wiping cloth and special cleaning agent. This kind of screen cloth has good water absorption and good dust absorption, dust will easily adsorb to the cloth, and will not re-adhere to the screen in repeated wiping, nor will dust particles scratch the LCD screen.
Clean up oil stains and sweat stains on LCD, use special cleaners, avoid using general household cleaners and organic solvents such as alcohol, they will corrode the surface of the display. In the computer market, the lowest LCD Cleaner Kit (detergent, brush, professional screen cleaning cloth) is only five yuan, while the big computer manufacturer's kit is about 200 yuan, using DIY methods such as clear water or vinegar, soft cloth can also be used.
However, it must be made clear that no matter which method is used, any liquid must not be allowed to enter the gap in the display boundary. There are many examples of liquid accidentally entering the gap and causing damage to the display. It is suggested that when cleaning, after 20 minutes of physical separation of power supply and data line, the display should be placed flat (to avoid liquid flowing into the gap due to gravity). After slightly wetting the screen cloth, pay attention to the boundary when wiping gently. Never spray detergent or water directly onto the screen (to avoid liquid flowing into the gap). When the liquid evaporates, it can be used later.
