Ionic foot detoxes are a popular way to remove toxins from the body by soaking your feet in an ionized bath. The process involves an ionizing machine that sends a low-voltage electric current to charge the water molecules in the bath. The charged atoms are said to attract and neutralize negative toxins in your body, and then pull them out through the bottoms of your feet. The water may slowly turn discolored, and some crud may float to the top of the tub.
