Clean your laptop keyboard frequently to prevent stuck keys and bacterial growth. Turn off and unplug the laptop. Shake the keyboard over a trash can to remove any debris from underneath the keys. Spray compressed air underneath each key to loosen any remaining debris. Dampen a cloth with a small amount of warm water and a few drops of dish soap. Wipe the key surfaces with the cloth and clean between the keys with a damp cotton swab. Allow the keyboard to dry completely. Vacuum the keyboard with a soft brush attachment or hand vacuum.
