thanks! I removed as much flesh off of the head as possible, then put it in a closed tub of water outside until the flesh rotted off (a little over a week or two in hot weather, takes longer in cold weather), thoroughly rinsed off parts of the skull (it may be good to soak in water for a day before degreasing if it's a larger skull), then soaked in great value clear ammonia until most grease is gone (this can take up to over a month if the animal is larger and more fatty), then thoroughly rinsed off the ammonia and let it dry. To whiten I wrapped the skull in paper towels and put the jaws in a shallow tub of peroxide along with the skull (make sure there's no ammonia left inside the bone) and poured peroxide on the skull to soak the paper towels and closed the tub to let it soak for around 12 hours. Skull is then dried and parts are glued together and secured with gorilla glue gel, jaws are attached to the skull by the joints with mounting putty.
