If you're going to boil the head, skin it first, and then only boil for a couple of hours. The longer you boil the head, the softer the bone gets and the nose parts will fall off. After boiling, take it to the car wash and clean it up real good then hang it up and let it dry. You might have to do a little picking to get it completely cleaned up.
I used to boil, but now I wrap aluminum foil around the antlers and bury the head with the antlers sticking out. If you bury it now, you can dig it up in late spring or early summer. The bones stay together better. Usually you can just clean it up with a pressure nozzle on a garden hose. The hair, hide and all will come right off. Again, hang it up somewhere to dry. The skull will have some coloration, but you can paint it or leave it like it is. That is the easy way to do it.
