cleaning bear claws?
 

Along with the skulls I picked up I was given some bear claws. They still have yellow tissue on the bone part with just a tiny bit of hair. Everything iv seen on cleaning is done right after it is cut off the paw. Can I boil claws? Or does that hurt the claw itself, I was also reading on lemon juice? How to make the claw shiny after cleaning it? One of those nail polishing boards?
