I have a couple of black bear skull from a couple of years ago that I did not take care. All the flesh is off but there is some green and brown stains on them. Is there anyway to bleach them out or are they stained forever?
The one is my dads and would like to give it to him for fathers day. I currently have them soaking in hydrogen peroxide, it has helped some but there is still a good bit of stain remaining.
