Besides cleaning your piano, there are a few other ways you can prevent sticking keys. It is important to note that some pianos have special lubricants in their mechanisms, so it is best to check with a technician before attempting to lubricate the instrument yourself. Additionally, keep in mind that pianos should be tuned regularly to ensure they are functioning properly and preventing sticking keys from occurring.
