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.
That's not how it works though

Thank you correcting my understanding! The part I find gross though is less the mechanism and more the result: that all the sweat my body is making is just stuck in the glands. If the anti-perspirant was simply absorbing the sweat as it comes out of the pores, then I would feel different about it.
So tl;dr they simply block the pores on your skin to prevent sweating?
Yep.
But it's the sweat glands, to be precise.
