I've got some deer antlers that have a nasty odor on them from the maceration tank. The antlers look flawless, no dark lines or "gunk" left on them but the smell will not go away. I've tried scrubbing with brushes, different scented soaps, spraying with febreeze, soaking in hot water filled soap and laundry scent booster (this was a temporary fix but after a day of airing out the bad smell over takes the good). What are you guys' methods for getting the antlers to not smell like a maceration tank? Thanks!
