Scuff marks are inevitable with wear and storage. Especially if you have a larger surface area.
Their removal is made easier with 3M Polishing Papers.
3M makes polishing papers of various grit (higher the number, the finer it is and closer to mirror finish you can get). If your scuff marks are deeper, you may want to start with lower grit and move your way up, finishing at 8000 (think of ridge removal in buffing nails to high shine).
These papers are available at any silversmithing store. (Full disclosure – this is not a sponsored ad and I did not receive any remuneration for this video).
