You want to use 40% peroxide no bleach.The peroxide can be purchased in beauty supply stores this is not the stuff from the pharmacy.Bleach will weeken the bone it is a oxidiser and the skull will turn yellow after a few years.After soaking in peroxide until white air dry and spray with someElmers glue and water It will look awesome.
Ditto! I picked up some at Sally's Beauty supply for a few bucks. I spread it over the skull (don't touch the antlers) and let it sit for a couple days. You can also put it out in the sun for a few days to help "bleach" it.
