I use non-antiperspirant deodorant. I got tired of the aluminum in antiperspirant staining my shirts and clumping up, then I learned that the aluminum works by being an irritant that causes an allergic swelling that blocks your sweat glands. That all sounds pretty gross to me. I might re-apply deodorant during the day if I’ve been sweating, or put on some fresh clothes or even take a light shower.
