I euro a few every year. I have done Bear, Deer, Elk, Antelope, etc. with mostly Deer/Elk. I use a similar method and just found some things to make it faster and save more bone detail. Key is don't keep it in a rolling boil (heavy simmer) as it will cause the bones to separate and spread apart along all the natural junctions.
Flesh Removal:
I use different sized pots on a turkey cooker, use a ladder over the top, and suspend the head so the antlers are as flat as possible against the water line. Avoids boiling color out and hardness white onto them. No need to fake color them back up.
I add Oxi Clean laundry soap in my water.
I cut a roll of saran wrap about 4" long and use that to wrap all the horn. This will fit under the bur nice and snug.
Secure the saran wrap with electrical tape as this also stretches under the bur. If you boil this too hot and in the water the electrical tape starts to loosen.
I clean a lot more of the fat and meat off before boiling.
Then I power wash it. This is what I use and it has been going for about five years. I used my big 5HP Honda.....yeah strongly urge you not to have more than 15-1600psi and less than 2gal min. Volume is important just leave the industrial in the shop.

CLEAN THE BRAINS OUT BEFORE BOILING! I scramble with a screw driver and use my power washer.
I do not touch my skulls with a scraper only a wire pick at the very end if there is a tiny piece. Pressure washer does it all 90% of the time.
Warning! There are some bones that are super fragile and care will preserve them....most of the time not always.
1: At the back of the nasal cavity just forward of the eye socket is a thin sheet of bone....paper thin. You can shred it with a washer or easily break it with any kind of scraper.
2: Spiral bones going up the nasal cavity from the front. These are full of what ends up being a dark rubbery flesh all the way to just below the eye socket. DO NOT STICK YOUR PLIERS, KNIFE, SCREWD DRIVER, etc. up there and try to pull scrape the boogers out if you want to keep the spiral bones. Pressure Washer, Pressure Washer, Pressure Washer....works perfectly just adjust what nozzle you use.
Whitening: I re-apply the saran wrap. ANYTHING THIS SOLUTION TOUCHES WILL BE WHITE SO PAY ATTENTION AND DETAIL MATTERS. I will tape off the teeth a lot so the dark stains contrast with the all white. I just use an eraser to push the tape into the cracks to lessen it from leaking down on the tooth.
I use 12% Hydrogen Peroxide off Amazon. I buy it by the gallon because I will eventually use it. I then mix Clairol Basic White powder and the Peroxide together to make a thin watery paste. Use a 1/2" brush to brush it on, and pour it down the navel cavity, etc. I put it on fairly thick and you can put a second layer if you hit it as it starts to set up. I have applied this several times, and most of the time it is done with the second coating. I use air hose to blow it off and a brush after it dries. You could soak it off....I just don't take the time to let it dry.
