I pour some of the liquid laundry soap into a bucket with water and scrub off with a scrub brush. Hang to dry & then spray down with scent killer spray. I know the scent killer spray kills human odors but I think the extra scrub down takes care of other scents like car exhaust , storage odor etc. I bag it up after cleaning & take out when I need it. I only stand hunt & I know my efforts help. Mike
