Tread lightly. It takes a micro second to destroy a blade. Catch an edge and crack of chip the blade. Fun it too fast and too long and burn the blade. Mirror finish is not all its cracked up to be. It took decades and sometimes a century of more to get a nice patina.

I remove dust with FOR and brass brush. Rinse thoroughly and start sanding. When it is where you want it then set sand with 2000 and up wet/dry sand paper and polish with Mothers.
