<HTML>Dear Friends and Collegues, Today I installed a set of lifter elbows (yes, old plastic breaking at a light touch of the key). The plastic keytops were fairly dirty and my client said that her mother told her to clean with rag dabbed with milk. While installing the keys, I gave her 2, 1 to clean with milk, and the other with water. The water did not do to well, but the milk cleaned the other key spotless. I have never heard about milk for cleaning anything, let alone piano keys. Is there something about milk derivatives that has cleaning agents? Will milk clean ivory as well? Yes, I had my milk today.
