Clean the keycaps: Wash the keycaps with warm water and detergent, and dry them with a clean cloth.

Clean the key switch: Use a compressed air can or vacuum cleaner to clean the dust and debris in the keyboard. For stubborn stains, use a cotton swab or a fine brush to gently wipe. Please note that do not pour water or other liquids on the key switch, which may cause damage to the keyboard.

Clean the base plate and circuit board: Gently wipe the base plate and circuit board with warm water and detergent. Do not pour water or other liquids onto the keyboard.
