Warning
Topical methylene blue is difficult because it stains your skin blue and for that matter, some painted surfaces and stone such as marble so you have to be careful handling methylene blue. If the topical application is for fungus, borax might be worth considering or the borax and diluted hydrogen peroxide which do not stain the skin.
