Hi, can I get rid of athletes foot by using a water to bleach ratio of 3:1? Thanks

Just use otc. Anti fungal cream for 4 weeks. Bleach can be caustic to skin and odor remains, especially when feet perspire.
I would recommend. You purchase over the counter anti fungal medication as it is proven to work well. Why start in with bleach? The fumes alone are likely not worth it.
