I do wash my stuff in baking soda. The thing I believe that helps the most is the way I store my clothes and stuff. Every year I cut small branches off of a cedar tree (Christmas tree) and put them in a rubbermaid container. When I wash my clothes I put them back in the container. Everything I take into the woods goes into the container. The cedar scent stays strong all year long. Of course your not going to totally extinguish all scent, but I believe this method of scent cover will hide you longer. Afterall there is no scent exactly like the real thing.
