I would't worry too much about sanitizing, if you use very dilute bleach while soaking , do a thorough cleaning especially around antler bases you should be good. Most bleaching is done with strong peroxide, not the drug store variety. If you are concerned about bugs, a little 20 mule team borax at cleaning time is good. Dry in Sun. If the antler's themselves look a little dry, some linseed oil thinned with turpentine or mineral spirits will take care of that. The Fabreeze wouldn't hurt. How many sets of antlers are you talking about?? Put on a big pot of COFFEE, dried scalps are a drag, but will soften up. P.s glad you can move your stuff in the house!!
