I have an older Ivorite handled Randall that is starting to show some discoloration. I do not believe this is a storage issue. Has anyone else seen this? I think it is simply yellowing, with age. Would you- attempt to clean it (peroxide, or vinegar and baking soda) or let it mellow?

Thoughts?

I would leave it as is, it's a beautiful material. Perhaps in the future it will become as desirable for collectors as the Westinghouse Micarta which also changed color. Does it change color evenly on all sides?
