How to clean the keyboard
Turn off your laptop before you do any cleaning. Even though you won’t be putting water directly onto your laptop, you should turn off the power to make sure nothing gets damaged if a little moisture does get inside.
Turn the laptop upside down and gently tap or shake it. This will remove big pieces of dirt, crumps (碎屑) or other debris (碎片) that’s hiding in your keyboard.
Tip: It may help to spread a towel under the laptop before you shake it, to make cleanup easier.
Spay between the keys with compressed air to remove dust. The air of the force will blow the dust that’s trapped between and under the keys.
Remove dirt with a cotton ball and alcohol (酒精). Alcohol evaporates (蒸发)quickly, making it a safe alternative to using water on your laptop. Alcohol is especially good at removing the dirt left by your fingers. In addition, alcohol is good at removing germs (细菌).
