RE: how do i clean up a skull?
I don't know where people get the idea that bleach is safe to use, but it's not. Itcan ruin bone very quickly. That skull needs cleaned before any whitening can be done. Let it soak in a bucket of water for a couple weeks. Some Dawn dish soap in the watermay help as well. After soaking, rinse and scrub with a soft brush and see how clean it is. If it's still dirty, let it sit for another week or until you think it's as clean as it's going to get. Then it can be whitened using peroxide.
