I use cedar tips boiled to a tea and strained (pine is good if it's more prevalent in your area) and put in a small spray bottle and spray all my stuff. The thing is...what do bucks like to rub most..cedar or pines! yeah I know they rub on small saplings as well.
When they smell a heavy scent of them it makes them think there is another buck close by,this works well in the rut.
I've even sprayed it and grunted when I thought a buck winded me, and to my surprise he came on in ( with his back hair standing up!)( p.s. dead deer!)
Although deer can smell extremely well, it's possible to "overload" their nose with something familiar and not so alarming.
It works for me!
