Keep washed hunting clothes out of the dryer, Scent from dryer sheets persists a LONG time. Yes use the Baking Soda detergent. Air dry them outside. I used to cut pine branches (usually had plenty from putting up my stands) Put the branches together with my hunting clothes in a large contractors trash bag. Out of the sun. Did this all season with some degree of success. Then Ozonics came out with their line of products. All I can say is that they worked for me, really well. Unfortunately they are not cheap and they take up a lot of room in the backpack, but..... That's what I'm carrying to my stand nowadays. Even to my rifle/shotgun stands.
