Several ways to take flesh off. I did one first time last yr. Get all off the skull first with a knife,eye balls, tongue. then boil, not rolling boil, though ,,for about 20 minutes in a big pot,keepin antlers out as much as possible. Put some dish soap in the water for some degreasing. Then take out let it dry, and I took knives,wire brush, finally sand paper, to get all the flesh off. Some use power washer. Got to scoop out brains, and all the crud up in the nasal cavity. I read on taxidermy site, then to soak inLaquer thinner for couple days to draw all the oil out of the bone. Not sure if required but I did it. finally got the bleaching kit from Taxidern catalog, like Mckenzie. Basically a peroxide paste. After that, brushed off ,,it's done! A little white paint if not white enough for ya,,but it is done. Down in brain cavity and nasal cavity, you might think still smells a little. I rinsed with more thinner, and some bleach. Finally I stuffed some cedar down in there, and left for a few days. No smells anymore after that.
