For about a year and a half now, I’ve been using plain ole Arm & Hammer Baking Soda as my deodorant. (I made the mistake of using a generic brand once and it was like rubbing sandpaper under my armpits!) I use baking soda about 98% of the time. No, it doesn’t eliminate sweating, but the sweat doesn’t bother me — if the rest of my body is sweating, I don’t care that my pits are too! — but it combats odor better than any deodorant I’ve used before (including the natural brands). Once in a while I will be in a situation where I don’t want sweaty pits to be seen, so I keep my Lady Speed Stick stashed away for those times (but, interestingly, my pits do end up smelling funky by the end of the day when I use store-bought deodorant).
