If this is in the wrong forum, I apologize.

I was in an antique store last year and found a vintage Old Spice mug that I wanted. Included with it was an Ever-Ready 1000 Pure Badger brush that has been sitting around since then. The knot was pretty shot but I liked the handle and figured I would re-knot it at some point. I started working this weekend and got the old knot out with a drill and a dremel wheel. It looks pretty nice but has a few scratches that are discolored which I would like to clean up. Can I safely use wet & dry sand paper on this or does anyone else have any recommendations? Please let me know what you think. Please excuse the not so great pics from my cell phone. Thanks in advance.
