Find a local beauty supply store and by whitening powder and 40 volume peroxide (liquid). You mix the two in a plastic container until it's like cool whip and paint it on the skull with a paintbrush. It will dry and then brush it off with a stiff brush. I usually repeat this "whitening" step to get it nice and white but that may not be necessary. After cleaning all the dried whitening powder off the skull, paint the skull with Elmer's glue diluted with warm water to seal the skull or paint/spray the skull with satin polyurethane to help seal it and give it a nice finish.
