There may be something else going on here. Several years ago, I heard of a situation, where the client kept the piano immaculately clean. Each time the tuner came to tune, the pins were looser! Eventually, the piano was untunable. The tuner found out that the client was spraying "Pledge" around the tuning pins to keep it clean!!!!!!!!!! "Pledge" has silicone in it. The piano had to have a new block, at the clients expense. Regards, Joe Garrett
