电脑屏幕怎么擦干净

To clean a computer screen, you can follow these steps:

1. Turn off the computer and unplug it from the power source.
2. Use a soft, lint-free cloth (such as a microfiber cloth) to gently wipe the screen in a circular motion. Avoid using paper towels or rough materials that could scratch the screen.
3. If there are stubborn smudges or marks on the screen, dampen the cloth with water or a mixture of water and vinegar. Make sure the cloth is not dripping wet.
4. Gently wipe the screen again with the damp cloth, being careful not to apply too much pressure.
5. Allow the screen to air dry completely before turning the computer back on.

Avoid using harsh chemicals or cleaning products on the screen, as they can damage the display.
