At the risk of being attacked by all you guys who realize that a museum piece shouldn't be steel wooled, I'm going to put my two cents in. Sometimes, you might want to make the thing shine instead of looking like it came from the bottom of some moat. IF THAT IS THE CASE, try soaking it in EVAPO-RUST first. This stuff can be purchased from AutoZone stores and it dissolves the rust.......not the steel. It removes the rust with abosolute minimal damage unlike elbow grease and any kind of abrasive anything. Once the rust is gone, you have a choice to oil it and forget it or maybe then use the abrasive stuff. That being said........if something truly IS a museum piece, don't do anything to it to devalue it.
