"Oiled metal will not rust". Gun oil, 3-N-1 oil, Ballistol, Break-Free, Rem Oil; all work. Some folks use Renn Wax.

On the grooves of the buttcap, maybe scrub Simichrome Metal Polish or Flitz Metal Polish using a M-16 toothbrush. Top off with Ren.Wax.

Nice model 18. Don't see many carbon steel 18's.
