So I’m just getting into doing some of my own skull whitening…. Feel like I’ve read thread after thread for hours and have done my best to learn without starting a new one to cover the same info, but each case presents unique circumstances of its own I guess. This year I killed two bucks, and also recently took a couple of coyotes, so decided to save some money and try to clean up the deer myself… and then figured why not play around with the coyote skulls while I’m at it. Long story short, in regards to the deer: I skull-capped both of them, so there wasn’t even much bone to clean up. But it’s still been a nightmare to get the smell out. I boiled, got all the flesh off, macerated in ‘water only’ for weeks with an aquarium heater (changing water every couple days), and then, once all flesh was 100% removed: (all with aquarium heater) -soaked in Borax 3-4 days -soaked in dawn dish soap for 4-5 days -soaked in oxi clean for 2-3 days -soaked in 10% ammonia “1/2 diluted” for 2-3 days Just kept trying different things because there was still a pretty strong odor. When all was said and done, one of the bucks in particular *still* really has an odor to it. I think I’ve pinpointed the odor to primarily up around the antler base…. But even though I’ve wrapped the antlers in foil/electrical tape/plastic wrap when I soaked them in ammonia and oxi clean, the bases of the antlers still faded badly because the solution crept its way up. So I know the bone was getting exposed to the solution since the antlers obviously were too. Basically, my question is: how do I further degrease/deodorize the bone at the base of the antlers without getting the antlers further faded/damaged? Like I said I’ve wrapped the antlers as tight as I know how and the solution is still leaking underneath a bit. Now, onto the coyotes… lol. One of the coyotes laid in a field for a month, probably Nov 20-Dec 20 or so. The other was killed on Dec 19, so on the 20th I took them both and started the process…. Boiled both heads, pulling and cutting away flesh every 15 mins or so. Macerated in plain water and aquarium heater for 4-5 days and got remaining flesh off. The skull that laid in the field was brown and the fresher one was white, even before degreasing. Then I basically did the same thing as I did with deer… Borax, Dawn, Oxi, and Ammonia soaks, same number of days, 2 days or so for each. I just took the next steps on the coyote and submerged both skulls in 3% peroxide for 3 days (in a dark room). Just pulled them out, and the one that laid in the pasture for a month is still pretty brown despite 10+ days of degreasing and 3 days of peroxide. Not sure if it’s grease, or iron, or just discoloration from the ground, etc…. But trying to learn what it is, and if it can be whitened or not — or if I am stuck with a brown skull. Picture attached. thanks in advance!
