Soak your feet for an hour in about a cup of baking soda only. Also in between soakings you need something to help kill the fungus as well. I would recommend making a dry mixture (basically a foot powder) of one part baking soda and three parts corn starch. Mix these two dry items in a mixing bowl and thoroughly combine. Afterwards find yourself a shaker container and pour the dry mixture into the shaker container. Apply this foot powder morning and night, wearing socks to help keep the mixture on while you sleep.
