The first step in taking care of the problem is washing your feet well. You also need to change your footwear often, and use cotton socks. Another way is to change your sheets weekly, so as to kill the fungus that are present. The most important step in getting rid of fungus is to keep your feet cool and dry. You can avoid sweaty feet by wearing open shoes, as this can avoid the fungus as well. This is according to information from, http://www.ehow.com/how_2314503_get-rid-foot-fungus.html.
After every shower, dip a cotton swab in vinegar and brush your entire foot with vinegar. Let dry. If you have foot fungus on both feet, brush both! Another way is to pour a mixture of 5/6 vinegar and 1/6 water into a basin and soak your feet in it for 5 minutes.
