I did use a natural deoderant for awhile that I got from Whole Foods and smelled like a creamsicle-- I liked that a lot. It would fail probably after four hours and smell a little musty but it was good. But I think that eventually I left it in the car too often and the heat degraded the ingredients' ability to kill off the armpit bacteria.
Anyway, so last night, after I got out of the shower, I figured I'd come here and check out some options. Zinc didn't work for me. I thought I saw a difference supplementing with zinc, but over time, no dice. I also got some zinc baby bottom paste and that just made my armpits smell musty. I had tried vinegar once, just running out the door and it did kill the smell but I never tried it again, for whatever reason. So I looked at the different options for immediately killing BO for the night, and decided on white vinegar.
I had already showered so I didn't want to shower again, so even though I shaved my armpits and was wearing a halter top I braved the possibility of angry red bumps, and took a cupped handful of white distilled vinegar and applied it to my pits, slightly rubbing it in. I let it dry while doing other stuff.
I am pleased to report that over six hours, the vinegar did not fail me, despite sweating and air drying several times. I detected a slight vinegary smell, but it was nothing compared to the humid spicy food-type wall of body odor that was coming from me before, and easily covered with a couple of sprits of body spray. So yeah-- rock on white vinegar!
