I am by far not an expert but I do have some success with deer that sneak down wind of stands from time to time. I really feel like nothing is 100% but reactions are minimal with curiosity being piqued more than deer spooking out of the area most of the time when deer get down wind.
One disclaimer I will throw out there is my wife and I have sensitivities to fragrances so we use free and clear detergent on all of our clothing year round (bonus that definitely helps). Starting in September, I use the green hunter specialties (green colored) shampoo and body wash on my hair until after hunting seasons close. I also use Dove sensitive skin bar soap year round (since I have skin reactions to scented soaps). Also, during Sept thru January, I also exclusively use Arm and Hammer unscented deodorant and anti-perspirant. Absolutely no fragrance used on my body from September through January.
As far as clothes go, I wash them in camo shampoo with no UV and hang them outside to dry. I have an old scent-lok plastic storage container with a good rubber seal that I use for storage of accessories, extra socks, gloves, facemasks, and extra camo. I had an ozone duffle bag that finally just wore out so I took the ozone unit to that and attached it to the scent lok container to make a second ozone storage unit. I bought a new duffle bag and use that on my way to hunt (it's about 30 min).
You may think this is overthinking it but it really does work well for me. I will wake up in the morning (or about 30 min before leaving for PM hunt) and turn on my duffle bag that has the socks, sock liners, glove, facemask and my base layers (first lite mismatched camo that I bought for cheap at end of season sale 6+ yrs ago). I also have a full set of uninsulated coveralls in with this stuff. I will put on sock liner, socks, base layers, coveralls and boots for the drive to where I hunt. On the way there I will have the outer gear I am wearing that day in the duffle to get a 15 minute cycle of ozone treatment. Once I arrive to hunt, I put on my safety harness, attach my outer layers to my backpack and head to hunt. I do not put on any outer layers until I am up in the tree and hooked into my harness. There are some mornings that I am really cold walking to the stand, but rarely am I ever sweating after my walk to the stand (if hot, I will tie my coveralls around my waist and/or walk with my shirt up to stay cool).
Once I am done hunting, I put the outer gear and any hats or gloves used in the dufflebag for a 15 min cycle on the drive home. Once I'm home the outer layers get put into the storage container. I then remove my coveralls, base layers and anything else I used for the hunt (base layers inside out) and run them for a 15 min cycle in the duffle bag.
I will add that when I'm walking to the stand, I also use ever calm deer herd in a stick on the toes of my boots at the start of my walk and then reapply about 100 yds or so from the stand I'm sitting in. Even if I rub against something that scent typically chills them out.
I don't typically post on here but I like reading everyone's posts! I hope you can take something from here that helps you and possibly allows you to have more success in the field. Best of luck this season!!!
