If deer are used to your scent they couldn't care less if they smell you. I had my own small farm and like Craig said the deer "knew" my scent. On my farm they would walk within 70 yards downwind(out in the open)of our campfire and not even blink. I could grill on the patio and the same effect. They would feed right there in the woods 50 yards away. I drove the tractor to cut the field and I could get within 20-30 yards before they ran. Same with my mower, they never even stopped feeding except to look over occasionally. I even walked the field barefoot in shorts to show a friend something and I was too lazy to get my shoes. We walked around a corner, down a path a circled right back 5 minutes later. What do we see but a buck eating grass right where I stood 5 min earlier barefoot! The scent never bothered them, but let them catch me moving even once in a spot they didn't expect to see me and all h%ll broke loose!
My point is...if the deer know you, the scent thing isn't huge. However, if you disregard the wind you will never see the GIANT BUCK that otherwise might have run through during the rut!
**Back to the question at hand***
Should you try putting out some kind of soap or dryer sheet scent? I personally would pass. The local deer might get used to it, but any non-local bucks prowling for does during the rut will blow out of there or never come in at all.
