Re: I have a dusty beaver.......
As strange as this may sound, I've seen it done several times at a hunting log I go to. Get a Big box of old fashion oat meal, pour it out on a large flat pan, put in oven at warm, for about 30 mins or so (depending on you humidity). Apply with hand in rubberized glove, shaking it out between your fingers, making sure it gets in and between all the fur. Let set for a few minutes, shake off excess then vacuum the rest. The Oat Meal absorbs any oils and crap that have deposited themselves. Needless to say, do this outdoors over a large trash can or such. This really removes the dust and crap from all furs as far as I can tell. The heating of the Oat Meal, just makes it really dry. It is applied room temp, by being super dry, it absorbs all the bad stuff. I'm sure you can use other things, to do the same job, but Oat Meal is cheap, and I know it works.
