Swimming with your clothes and drying them carefully is usually good enough to prevent any unpleasant scents. The main use of soap is to break up the oils, but you can also do that with hot water. So, with no special gear, you could heat water over the fire, wash clothes in it, and then dry them on a branch or something.
