b. Keep Your Piano Covered: When not in use, keep your piano covered with a dust cover or close the lid to prevent dust and debris from accumulating on the keys.

c. Control Humidity: Use a dehumidifier or air conditioner in the room where your piano is located to help control humidity levels. This can help prevent keys from sticking due to expansion.
