I used to skin skull,then light boil/simmer,(outside as stated earlier,on a Coleman,with just a squirt of dish soap.(keep antlers from pedical UP out of sol'n) Scrape remaining meat and muscle.Smells like hell,and is messy,but gets it done.Then I'd soak skull in 30 vol peroxide (hair bleach),again,keeping antlers OUT) for a day or two.Have also used regular bleach,diluted,for a while,then to sunshine.Comes out very white.
Thru trial and error,and other's tips,I went to regular peroxide-$0.80 a quart at China-mart-works as well,just takes 3-4 days instead of one,and doesn't burn hell out of your skin.MUCH SAFER.
Now,if you are doing mutiple skulls,here's an EASY,albeit,messy way to get them done,thanks to Herne,from another hunt board:
He boils,as above, for an hour or so,WITH THE HIDE STILL ON-just like you removed the head.No fooling with jaw,tongue,etc.Then suit up in rain gear,with goggles,and fire up the pressure washer.You'll have to use a cinder block to brace them.Then let 'er rip.AND,keep your mouth closed.Don't ask me how I know,just know that it tastes WORSE than it smells.Gets them clean and FAST! I used 11hp model,which was too much.Herne goes with 5 or 6 hp.Be esp. careful when you do the hole in th back of the skull (atlas?).You'll get a direct splashback.After a few,you'll get a good feel for angles,etc.
I usually wait until I've got a few,or do some for others.If you're going to make that kind of mess,best to just get it over with.Also,do it away from everything-they'll be hair,hide,meat,everything flying around.
I've seen folks spray them,afterwards,with white spray paint,but I leave as is.Then either mount them as is,on a shaped,routed,and stained oak or walnut board.Will try a pedistal next.Dave
