I would wash the heck out of it with Dead Down Wind laundry detergent, let it air dry outside for a day, then I'd build a nice smoky wood campfire & smoke the heck out of it with wood smoke. At least 4-6 hours. I do alot of hunting on the ground, and wood smoke all of my outer layers. I believe that deer are not alarmed by the smell of wood smoke, and my experiences with them proves the theory-at least to me. I've had does, fawns, & younger bucks within 10-15 yds of me and they haven't spooked. The big guys? not so much-that's why they're big guys! Hope this helps!
