I have inherited an older western saddle for my daughter. She will be getting it for Christmas. It's in amazingly good shape for 35+ years old and the leather is cleaning up magnificantly. It has silver conchos on it that have become discolored and I'd like to clean them up. I want to clean them up but don't know what to use. My dad and I are afraid that the silver cleaner you would use on a tea set or utensils would damage the leather so I want to know what I can use to polish it without hurting the leather.
