Keep your computer physically clean

A dirty keyboard doesn't look nice and can cause your keyboard tonot work properly. Dust, food, liquid, and other particles can get stuck underneath the keys, which can prevent them from working properly. Check your owner's manual to see if the manufacturer has provided you with instructions for your specific keyboard. If so, follow them. If not, the following steps are basic cleaning tips that can help keep your keyboard clean.

1. Unplug the keyboard from the USB or PS/2 port. If the keyboard is plugged into the PS/2 port, you will need to shut down the computer before unplugging it.
2. Turn the keyboard upside down, and gently shake it to remove dirt and dust.
3. Use a can of compressed air to clean between the keys.
4. Moisten a cotton cloth or paper towel with rubbing alcohol, and use it to clean the tops of the keys. Do not pour alcohol or any other liquid directly onto the keys.
5. Reconnect the keyboard to the computer once it is dry. If you are connecting it to a PS/2 port, you will need to connect it before turning on the computer.

Dealing with liquids

If you spill liquid on the keyboard, quickly shut down the computer and disconnect the keyboard and turn it upside down to allow the liquid to drain.

If the liquid is sticky, you will need to hold the keyboard on its side under running water to rinse the sticky liquid away. Then turn the keyboard upside down to drain for two days before reconnecting it. The keyboard may not be repairable at this point, but rinsing the sticky liquid off of it is the only chance for it to be usable again. The best way to avoid this situation is to keep drinks away from the computer area.
