I used powdered bleach and peroxide 40% which both come from a beauty supply store. The hardest part is picking all of the material from the sinus cavity. I found a pair of 12" tweezers at my hardware store and they helped. Acetone pulls out all of the greese and oils too. Boil it for two hours pull out all the meat, eyes, brain, gook and stuff. They put in clean water and boil it again and get the rest. It really is a three day project before you get to dry it and bleach it.

It was well worth it.
