You can use a very dilute solution of vinegar, blue and rust remover (phosphoric acid), or naval jelly to dull the finish, but too strong a solution or too much time will strip the bluing altogether.

Reading some forum posts from engravers who do a "french gray" technique, I see a lot of talk about using a pink pencil eraser to polish gray finishes.

Just some thoughts.
