Get that out of my house!

Soak it in a hydrogen peroxide/water solution for about 7 days. That'll help with the smell and also helps bleach them out a little more.

I used this stuff this year and only requires 24hr soak to get the smell out and helps clean them some more

I have stuffed a couple dryer sheets into the brain cavity before. Once it dries out it should be fine

Soak it in acetone.

 If the skull was properly cleaned it would not have any bad smell but many times the antlers get pretty stinky from being  submerged in the degreaser. Is it the skull or antlers?  If it's the skull it needs more work.  If it's the Antlers it will be pretty easy to remove the smell .

More than likely you still have some "meat" either in the ear canals or deep inside the naval cavity.  Without beetles getting into the tiny crevices in the ear canal that junk will be nearly impossible to get out without breaking out the canal.  It's super easy to do and you don't notice it on the final product.  Just take a screw driver and insert it or hammer it into the canal, put some force down and most of that canal bone should break free fairly easily.  Once you do it, you will easily see what bone will "break out" or come out easy.  Almost like an entire separate bone section to the skull.  It's amazing how much tissue gets left between that and the skull.

Peroxide. It will clean all the parts you couldn’t
