Bubba, I'll suggest that deodorant is not a problem. A physically active person living in the tropics, I've been sucessfully using sodium bicarbonate (baking soda) for years. It's dirt cheap and keeps forever; one problem solved, only 999 to go! : )

It's a cleaning solution, a deodorant, u can brush your teeht with it. You can bake with it. What is it? Bicarbonate of soda.
