This is not a recommendation but a history of my husband.
Before I met him he broke his leg in such a way that it required Titanium rods, bolts - etc. His body rejected it - and expressed it in his foot in a type of fungi similar to athletes foot. He tried all the remedies prescribed by the doctors. Nothing worked.
For some reason HE decided to use bleach. He soaked his foot in a diluted solution and let it air dry, and he poured bleach in his shoes (tennies) and let them air dry. One treatment was all it took. Fungi gone. Every now and then it returned and he'd repeat his bleach "therapy" once and be good for months or even a year.
