RE: Cleaning skull plate
Just take a knife and skin off the hide from the plate, when you get to the antler burr you can use a screw driver to work your way around it if you have trouble (prying up the hide) then use your knife to remove any excess meat and tissue, cover the skull plate in borax and let it dry for a couple weeks. Must easier and smells better than boiling it. Then mount it with your kit. good Luck!
