I picked up an old W&B wedge with black horn scales period correct late 1800's. The scales are in good condition but dry and showing their age. How best to clean and polish the scales. The blade is in good condition and won't require much more than a dremel wheel and polish and a refreshed and sharpened edge. I want to get the horn in the best condition and I'm not interested in replacing them. I'm thinking some toothpaste , brush, and some wax. I have also thought some wet sanding w/2k or better might be an option. I'm looking for some ideas. Thanks in advance.
