I always wash my hunting cloths in the washer with no detergent. Then dry them. I don't do anything else except clip one of those fresh earth scent wafers on my hat. I have deer and coyotes both walk right under my stand usig the same trail I walked in on. The guy I hunt with smokes so there is always at least one cigarette smoked during the 30 minute ride to our hunting spot. Not saying that deer can't smell but sometime I wander if we make too much of it. We each have one stand we hunt on the property so the wind doesn't affect where we go. We both see plenty of deer.
