what i did was use a turkey fryer. I happened to have a pot that just fit the skull in it without the antlers going in the water. Then just boiled it in borax for about 2 hours and took it out and hosed out all the brain matter and nasal stuff, then put it back in and boiled it for another hour or so and hosed it out again. If a tooth or a piece of the nose breaks off don't worry they glue back on just fine.
