I simply run my camo through a basic wash cycle with baking soda, take outside and air dry. I never use the dryer for anything. Beats things up too much. Then I put my garments in a GIANT zip-loc bag if I'm going away to hunt. Otherwise, my cloths stay hung up outsidein the fresh air until I go hunting.I repeat this process throughout the season.
Oh yea, I ALWAYS use Scent Killer (unscented).
