Cover scents are a dry hole. If you have pit stink or some other odor on you, nothing will cover that up. You need to get rid of it. Check out my piece on Baking Soda:Baking Soda -- The Shamanic Method
. . . and if you read my stuff regularly, you'll know I'm the first to admit this is probably overkill, but baking soda is cheap, cheaper than detergent, and it seems to work.
Shaman and I have had a few discussions on BS(baking soda).
I too have been sold on it for a few years.
EVERYTHING I have is exposed to BS.
I use a scent free detergent once a year. During the season if I have to wash my clothes and such its with just BS, dried, then stored with again with BS in plastic.
I also do bath in scent eliminator.
No way we can get rid of all we have when it comes to human smell. We can eliminate it as best we can, but not all. Best we can do is keep it to a minimum and let it appear that the bits of odor the deer are picking up are "old".
As for cover scents. I will also store my clothes with oak leaves (they are free), I really like the smell, and when I put them on it makes ME think I am invisible in the woods. Doubtful the deer do. But if I think it raises my mental game when I am out there, so why not.
In the big pic though, they say a buck can be many many many yards away from a scrape (or a doe) and tell if she's in season. Never have to even poke his head out of the thick stuff to scent check. So I doubt any cover scent would really hide your odor.
