A good soak in a biological soap powder solution is pretty good at
cleaning up bone.
And where does one get this?
I have, in a shed in my back yard, my Christmas gift from one of my
daughters who is a wildlife biologist. Knowing I love skulls,
antlers, fossils and other such, um, arcana, she brought the head of
a 10-point mule deer killed by one of her study subjects, a puma.
She did bury it for a few months, but it is still far from clean.
Because of the huge antlers, it won't do don in my largest stock
pot, and my mid-winter attempt to boil it out in the back yard with
the hotplate I use for kum boo only resulted in a foul-smelling
"stew"... I gave up when snow started pelting down. I haven't had
the courage to go look at it since, though it will be spectacular
