Starting 2 weeks out from deer season, I would start washing myself in scent free soap when showering. It was odd because I got out of the shower smelling like nothing. I would also religiously wash my clothes in scent free soap; I tried all the scent blocker or whatever and realized I was getting ripped off when All free and clear was a fraction of the price per ounce.
I bought an ozone machine to clean my truck and my clothes as well. Seemed to work pretty good, my stuff basically smelled like nothing.
I believe in hunting the wind, but I also know that sometimes the wind won’t cooperate for days at a time where I was hunting. I tried to hunt with my face to the wind, but as circumstances dictate it doesn’t always happen and therefore had a pretty strict routine to deodorize myself. I’ve had deer directly downwind of me from 5-30+ yards and they hadn’t indicated via their motions that they’ve noticed a strange smell in the area.
ETA: always wear rubber boots. I always tried to walk through a creek/ditch/whatever to get some water and mud on my boots before entering the area where my deer stand was. I’ve yet to have one curiously follow my foot trail in, or spook because they ran across my trail.
