How To Clean A Keyboard
A grimy appearance is just one reason to clean your computer keyboard. If dust gets stuck underneath the keys, they might not work properly. And spilled liquids can be your keyboard's death knell if not taken care of. Here are a few easy steps to get your computer keyboard clean.
How-To Steps
Step 1:
Purchase any supplies you need: compressed air (in an aerosol can); a soft rag; Endust for Electronics, or any nonabrasive household cleaning fluid suitable for cleaning plastic; and a dust mask if you're allergic to dust.

Step 2:
Check your owner's manual. If the manufacturer has provided specific instructions, follow them.

Step 3:
Shut down the computer.

Tips & Warnings:
In industrial or other high-dust environments, use a plastic keyboard cover to protect the keyboard.
If you've spilled a large amount of liquid, or if the liquid is sticky, it's likely that the keyboard won't be repairable, although you can certainly try. To be safest, though, keep drinks far away from your computer.
If you've spilled liquid on the keyboard, turn it upside down after you disconnect it to let the liquid drain out. If there's a lot of liquid, or if the liquid is sticky, wash out the spill with running water. (Do not immerse the keyboard). Let the keyboard drain for 72 hours.
Do not spray fluids directly onto the keyboard.
 Disconnect the keyboard.
Use compressed air to clean between the keys. Spray at an angle to dislodge dust and grime.
Shake loose dust gently out of the keyboard.
Wipe the keys and chassis.
