Dear list, over the years, I have had request to repair keys that had fallen lower then there mates, as stated by the customers. or keys will not respond to there natural height. In three instances, I had found that the technician in front of me used a vacume system to clean these pianos, without taking care, as he was sucking the dirt from under the keys he was also at the same tim, sucking away the worn out bushings, front and balance, in one incident that technician said he would respond back as he had to get parts, but never did show up. another tried to sell the customer a job to relevel the key bed, seeing what you are cleaning saves loads of problems, creates better relationships with customers.
