This is more than likely the last subject that would appear on a duck hunting forum. My daughter and her husband are returning to their hometown area. They are both teachers and have jobs in our local district. Jeremy is the boys Head Basketball Coach and Leslie is a Special Ed teacher. They are building a new house on a farm that was settled by Jeremy’s great, great grandfather. The old house has been razed. Before is was torn down they salvaged an ornate door that Leslie wants to use on her pantry. The door was not a problem, it looks great. The problem is the door fixtures, they are solid copper and are black as a Mennonites hat. I have tried everything under the sun but nothing has worked. I do have 1740 electric motor that I sometimes use in carving decoys. The best I have been able to do is get a little copper color on the edge of a door knob. If anyone has any suggestions, I would greatly appreciate them. My old Army stand by, Brasso will not touch it.
