[Bakes]

Get yourself some peroxide from a chemist 3 or 6% solution. Fill up a bucket so the water is just over the skull and pour in the peroxide. This will get into all the nooks and crannies and nerve holes and eat away any left over or dry meat and other bits. You may see some bubbles streaming out, thats alright. Leave for about two days. Then take out and rinse well. Then I would soak in bleach for about 1 hour. Agitate so all the bubbles get out. Then look at the skull and see if you have to make it critter friendly. Look in the nose, you may have to put a screw driver up there and break off the thin bones in the nose (so the animal won't get stuck.) Check any other places that a critter may get stuck in and block off.

Hope that helps
