Best Aluminum free deoderant?

I use that chunk of rock salt stuff, mostly because anything else causes itchiness and irritation. Depleted uranium? The burn pits of Iraq and Afghanistan? Asbestos from buildings built during WW2? Anthrax vaccinations? Long-term use of antimalarials? Nothin'. Deodorant? AHHHHHHHH IT BURNSSSSSSSSSSSSS USSSSSSSSSS
