If it's just the odor from the bug tank, I've had good luck submerging the antlers in water with a little dawn dish soap and 10% ammonia from ace hardware. I just heat the water up somewhere between 130-150 degrees for about 2 to 3 hrs. Works well with very little color loss and no damage to antlers.
This seems to be the easiest and cheapest, because if I'm not boiling water, I can do it with a cheap plastic storage container that I already have. Still waiting on my Euro guy to get back to me, but if I don't hear back soon, I'll probably do this soon.
