For topical applications I have had by far the best luck with Tea Tree oil. No, I haven't used MMS on them because UT has cured it. However, somewhere in this MMS board you will find that ingesting MMS cured someone's nail fungus. The fungus is in your blood stream and has to be killed there, and toenail fungus is tough to beat. It gets into your socks, shoes, bedding, shower area, and in the carpeting if you walk around without your shoes on. It lives for a long time outside of the body.
Here's the link to the message where the MMS user cured toenail fungus - and jock itch too. This was done through ingesting it, not topical application.
The statement in that link:
"Toenail fungus has been eliminated. I only take MMS internally. If this
has happened, then MMS kills fungus. It took a little more than a month. The
fungus was not reproducing. My toenail grew out; and I eventually clipped it off
little by little.
Jock itch is gone as well. I believe this is also a fungus."
