The monitor is the most used hardware of the computer system. People often touch the monitor to turn it on or adjust the screen while using the PC. This can leave fingerprints on the screen, which might make it blurry. Moreover, dark-colored screens catch more dust, so they must be cleaned regularly.

You can get your hands on different liquids specially made for cleaning the monitors. But it should be ensured that they are suitable for your screen.

  • Please take a picture of your keyboard so you can remember the order of the keys. When done, take them off one by one carefully to avoid damage.
  • A flat object, such as a screwdriver, can be used for removing the keys. Please ensure you are gentle regarding space bars because it can be difficult.
  • After disassembling, you can wash and dry the keyboard keys for a few hours.
  • When dried, you can reassemble the keyboard by looking at the picture on your mobile phone.

Cleaning Mouse

It would be best if you unplug your computer’s mouse when it comes to cleaning. When done, grab a clean cloth or a soft brush to rub on the buttons. You can use a small amount of rubbing alcohol to remove the stubborn stains. If you see something stuck between the buttons, you can use a toothpick to remove it.
