After having done 30+ euros and 2 bears I thought I had a pretty good method down but this skull kicked my butt.
It's been a 5 month process, so I'm sure I will level out some details, but essentially my POW bear skull was just heinously greasy.
Cleaned the skull using my sous vide, you can see all the grease. 72 hours, at 135 with oxiclean

Sous vide with dawn and ammonia (grocery store crap) for 2 weeks at 125... didn't so shit in my opinion

Soak in ammonia for 2 months, possibly worse?

Did a deep dive into the interwebs of taxidermy and got acetone

Post acetone for 2 months

Soaked in dawn for a week

Then I got ammonia hydroxide from ace hardware and did that for 2 months, then I rinsed it and soaked it again for a week in dawn... didn't take pictures because now it was hunting season and I got busy. Final product from the last step was pretty good so I went ahead and whitened the skull.
After whitening.

Part of the impetus for getting all the grease out is I think I want to have it nickel platted by ironcladmetals in Denver... and it needs to be grease free.
Anyway, if you have a greasy skull I would go straight to acetone and ammonia hydroxide.
