Ryan,
Easiest way is to Skin the head and boil the skull. I just put a large stainless pot on the grill side burner. Boil it for about a hour. After you boil the skull just take a pressure washer to the skull and the skull will come 100% clean in 15 minute!! I have done at least 25 this way and they come out fantastic. If you really want to whiten the skull after it drys brush on some straight bleach on the skull and let it set for about 24 hours then rinse really well. Repeat the bleach as needed. I don't do the bleach anymore but it does really whiten the skull...Mark
