F. Badger...
I'd use an old gunsmith's "trick" on the surface rust on the metal...
Get some super fine steel wool... I believe it's called "4-F" or possibly "5-F" steel wool, can't remember which... but get the FINEST grade of steel wool. It should feel "soft" and not like it's made of steel. Spray some WD40 on the steel wool and
VERY LIGHTLY rub the steel wool on the surface rust on the rifle's metal.
Do NOT rub too hard or not only the rust will "disappear", but the bluing will also "disappear.I bought an old, used muzzle-loading, black powder rifle that was covered with surface rust. Because it was so "rusty" looking, I was able to buy it for just $25. I used this same method (fine steel wool and WD40) on most of the rifle's metal parts and now, the rifle looks almost like new. All the surface rust is gone and except in one small place where I rubbed too hard, the rifle's bluing is totally in-tact and very nice-looking.
I realize this sounds "crazy", but... no joke... it WORKS !~!~!
Strength & Honor...
