With greasy animals like badger, beaver, raccoon, and bear you need to wash them thoroughly with a degreaser.
Flesh it as well as you can and then salt it. You don't need to put it in the freezer if you salt the hide. It can stay salted for a few months until you are ready to tan it.
Once you are ready to tan the hide wash it with a degreasing soap like Dawn dish soap. Rinse it off and tack it out. Now use the rounded edge of the scraper tool to scrape the hide. This will open the pores and bring more grease to the surface. Wash the hide with Dawn again and it should be ready to be tanned.
