I wash on the longest cycle-plain water then hang outside (sometimes for days)& then put in my camo cloths bag & into my hunting vehicle .
If I am away & hunting out of state I wash them the same way & always try & hang outside. I am concious of house scents-food, scented things.
I used to pack them in leaves from area I hunt. I also used to carry in a pack until I was about 100 yds. from my stand & then change cloths so I had less body oder.
I do not use any artificial coverups on my cloths or while Bowhunting but do use sex deer scents-deer drag ect. good luck to all this fall.
