Beyond using unscented products for personal hygiene and laudry....keeping as clean and uncontaminated is about as far as I go. My hunting clothes are stored in a rubbermaid tub, to keep odor free, with the exception that I might include some sagebrush or juniper branches, etc. to the mix in the tub.
I'm with most in that I believe you cannot comepletely mask your scent. You can, however, be "clean enough" to sometimes get away with being detected as "dangerous"....does that make sense? Especially in areas where deer are accustmed to seeing/smelling humans regularly.
I use milkweed or something similar to "watch wind"....a fun way to pass the time, but I try to know ahead of time which way it is blowing and which way it will switch come sun-up or sun-down via thermals. I set many stands for all options possible, I only hunt areas where I see bucks of the kind I want to take, and I hunt as much as possible, especially during those times when I can use tactics to maximize my chances, and when bigger bucks are "less cautious".
No real secrets from me, just a lot of time afield and luck jumps on my side about every other year for a nice buck. I do take several does each year, and they are every bit as cagey, IMO as the bucks are. Just more of them. Have fun figuring it all out.....that's the real prize!
