Get some light metal polish. Will work on the scales and blade. Blue magic is the lightest, on to Maas, and semichrome.
Auto parts/hardware store! Get some of those thick 'shop towels' paper towels. Cut little squares out for use in applying and rubbing. Full towel to wipe all off and shine.
Watch those fingers and mind the direction you are going. Away from the edge! With the edge. Just never toward the edge. Top to bottom on the blade and anything goes on the scales.
