Rain wears aluminum-free during the winter and scary-aluminum stuff during the summer. I never wear the aluminum stuff, but I'm not as self-conscious about some occasional odor, I guess. This is the best solution we've been able to reach. I'd prefer that she wear aluminum-free all the time, but it's her body...
We've gotten lots of natural deorodants for cheap at
Big Lots, just BTW... they had Toms of Maine for a while, and then Nature's Gate Organics... all for a buck or two each.
