I learned a long time ago that being scent free is impossible and trying to be scent free is way to much work. I enjoy my hunting alot more by just hunting the wind. I do agree to use un-scented detergents and soap.

I wash my clothes in Arm and Hammer Baking Soda Laundry detergent...unscented.
Dry with an earth scent dryer sheet... and store in an air tight plastic container.
Use a good cover scent during the hunt.....
Unscented shampoo...
Hunt the wind...
And most of all...wear fresh clean clothes everyday!!
