The only thing wrong with baking soda is that it will fade your camo quicker then the special hunting soaps. For many years i used baking soda with great results, just that it faded the camo.

I use special hunting camo wash, air dry outside, once dryed, I spray them down lightly with scent eliminator, then store them in a large heavy gauge plastic bag, get dress when i get to my hunting area, same goes with my boots.
