Beach-water 1/10 is effective as a wash for the scales that build up. Organic Apple cider vinegar-effective.
Coconut oil will help stop the itch and speed healing. Knowing the properties of Tea Tree oil as well as vit E I would believe they work as well. Nothing is going to be an overnight fix. It takes time and patience. Clean effected area twice daily with the bleach solution and pick one product/home remedy and stick with it. I have worked at an animal shelter for years and all of the above work fine. Like I said-patience and TWICE a day. Most people who do not find relief even with the over the counter athlete foot creams are not cleaning the area and then applying a thin layer of cream. Too much is not better.
