No, no steel wool! Hate to be contrary, but before you use steel wool, try this.
Soak the rust spots with kroil or marvel mystery oil and take a round bladed screw driver, such as a philips....be sure it is round blade, and rub it briskly across the rust spots, keeping the rust wet w/oil. The rounded surface of the screw driver will not scratch the bluing adjacent to the rust and the rust will be worn smooth and blend in with remaining finish.
Steel wool can remove the bluing, leaving a bright spot if not very careful.
