How many here treat or spray their hunting clothing? About a week or 2 before season I hang all my outfit on the clothes line for 2 days to air out. Then pack them in scent free bags. For archery I add the white oak acorn wafers. For gun season I add the doe in heat wafers. After season I air them out again and if dirty wash them in a UV killer detergent. Spray them down with scent killer and pack them away till next season. I very rarely have deer blowing at me. I have had them come in with nose up looking around from downwind.
So I get hold of a bar of actual lye soap. No scent. If you know somebody who can make soap, that's great, or you can order a plain bar of lye soap online.
I usually wear reproduction clothes from the colonial era, since I'm using a flintlock muzzle loader. A craft knitting lady made me a knit hat in blaze orange and I wear a shoulder "cape" on my hunting shirt that's also orange. I mean I'm out for the experience but I have to comply with orange regulations too....
So what I do is I grate the soap with a cheese grater, about a cup's worth, and I put this into the washing machine set on Small Load, and Hot water. The lye soap dissolves and I let the water sit until the water hits room temp as some of my clothing is wool, and I don't need it to shrink. I soak the clothes with the machine off, for a few hours, then switch the washer to empty itself, and let it refil with cold water. I let the clothes sit for about 30 minutes as a rinse with the machine off...(OH I almost forgot, I check the local tap water before I do any of this to be sure they haven't had a chlorine dump into the system)..., After that I then switch over to spin dry. Out they come and they get hung up to dry. No added scents, and no color brighteners. (I have a friend who does the same thing but he prefers baby clothes detergent without scent or dyes)
After a full day they are dry, and THEN they get hung up outside with a black, scent free garbage bag around them. The bottom of the bag I put in a few trowels of shredded mulch. This gets closed up around the clothes, and gets hung where the sun heats the bag during the day. After about three days, they are ready..., they have a faint "loam" or "dirt" scent that I can smell, and I figure the deer can as well.
When I'm wearing the clothes and get to where I'm hunting, I gently scrape away the twigs and dry leaves to get down to actual soil/loam where I will stand. This helps me keep quiet as I don't do tree stands, and puts some more dirt scent into the air.
NO IDEA if this works, BUT...., so far it doesn't seem to hurt my chances of getting a deer, and it's pretty inexpensive and not complicated.
