We have a creek that runs near our house, I go get a 5 gallon bucket of creek water and use a box of baking soda. I put all my clothes in there and use my hands to swish them around. hang them outside to dry, then they go in a container and stay out in the shed.

I do my socks last since they contaminate the water the most!!!

I feel that 1) you can never get ALL of the detergent scent out of your washing machine and 2) the water we use is treated/chlorinated or whatever, but it has a different smell. Good ol creek water is what the deer are used to smelling.
