I had a lot of fawns follow me to my tree when I used a product called "cover up" many years ago, I it was nothing bit vanilla extract, at least it smelled like it.
I had mixed results with the various flavor of the day deer attractants and cover scents, mostly negative with an occasional buck that would show an interest in them.
I remember when skunk scent was the rage, phew, then fox pee, which wasn't much better.
I used to do all the scent free routines, now I don't wear camo, wear my hunting clothes unwashed for months (wool) until they get blood on them and hunt the wind. I actually have more opportunities to kill deer than I did back in the unscented days, I let most of them walk though.
