Using MMS for unexplainable and persistant rash

My husband has a terrible rash that is unexplainable and challenging to treat. I have been trying to treat with everything imaginable...herbs, homeopathy, salves, grain & dairy elimination, eye of newt... Finally pulled the MMS out of the fridge to give it a try---DUHHH, can't believe it took me so long. Anyway, I made the 32 oz drink ( with baking soda & 1 drop of peppermint oil- delish:-) and the skin spray, and he's doing the bath soak.
My question, does anyone have positive experience with treating skin rash w/ MMS?
ALSO has anyone used MMS in an out door hot tub. It seems to me that if works in a regular tub we could use it in the hot tub too? Any idea how much to use AND I'm wondering if I could use MMS to keep the hot tub water purified.
I would love to hear from anyone who has used MMS in the hot tub and to treat a rash.
Thanx soooo much~

For sure it'll work in an out door hot tub. We shouldn't inhale too much of ClO2 gas, yet in the open space it wouldn't be a case. MMS is widely used as a disinfectant and a purifier in food industry, automotive industry and many others.
According to the rash... if the cause of rash is fungus I wouldn't cure it with tubs, but with CHEAP SALVES AND POWDERS THAT CAN SAVE YOUR LIFE .
