I fully believe that a stand is effected by your presence long after you've left. Meaning that you'll stop seeing deer (those that care) very shortly after you start hunting a stand due to lingering scent. I've never done anything that let me cheat their nose while on stand. A downwind deer will smell me no matter what I've done.
Now to let you on to my special brand of crazy...
I try to keep my clothes clean. Ozone is great for that. I don't use ozone in stand.
I don't touch anything with my hands. I have gloves that I wear going to the stand, and a second set of gloves to climb my stand and hunt with.
I sometimes place stones to create an entrance/exit path to step on. I've had both deer and yotes follow my trail through grass and leafs hours after walking in. They don't do that when I can step on flat rocks, and not have to brush against vegetation. Plus it's quieter.
