Oi, magnesium oil spray is working for me as a deo. Try it?
Magnesium chloride flakes are what you buy and then mix into water, and spritz onto the skin.
I got my flakes three days ago, I had been having armpit odor since I've been detoxing with the raw diet. The scents stopped after the first time spritzing. It came back a little today since I didn't spritz, but it might be a workable solution for you.
Having low magnesium in the body is an issue to begin with, in being unable to detox. As for chlorides.. well, very useful molecules. (http://www.second-opinions.co.uk/magnesium-chloride.html#.Vf2azCCqqko cited here as antiseptic. Think septic-tank. )
