-----Original Message----- Tom, I merely wanted advice on preventing additional oxidation, as this tends to mess up the flange screw threads and decrease the longevity of these quality instruments. Thump Mr. Thump. Mess up flange screw threads? How can a steel screw threaded into an aluminum rail be affected by the powdery stuff on the surface of the rail? The aforementioned screw may be tightened occasionally and unless a foreign substance, (water for example) comes in contact with the screws, the piano will turn to dust before the rail or screws become a problem. Speaking for myself I'll place my concerns elsewhere.
