1
Power off and disconnect
Unplug the keyboard or shut down the laptop. Remove batteries from wireless keyboards.
2
Tip out loose debris
Turn the keyboard upside down and tap gently.
3
Use compressed air
Short bursts at an angle. Hold the can upright so no liquid propellant comes out.
4
Wipe the keycaps
Use a cloth lightly dampened with isopropyl alcohol. Never pour or spray liquid onto the keyboard.
5
Mechanical keyboards: remove keycaps
Use a keycap puller. Photograph the layout first. Wash keycaps in warm soapy water and let them dry completely.
6
Laptops: leave the keycaps on
Laptop keycaps and their clips are fragile and easy to break. Clean around them instead.

After any liquid, let the keyboard dry for at least 24 hours before reconnecting.
