I know alum blocks are normally sold as a post shave product. I love them. However, I don't use them as a post shave treatment. They make the best underarm deodorant I have ever used. It kills the bacteria that causes odor, but doesn't stop the body from perspiring. Just curious if anyone else uses alum blocks as an underarm deodorant?

I regularly use the same alum as @Barrylu described. However, I don't use the RazoRock alum stick, or any alum, as a deodorant. Instead, I keep it on the counter during my shave so that I can touch the stick if my fingers holding the razor start to get slippery. Also, I really enjoy using the Osma alum block and a cold water rinse on my face after the shave, whether or not the shave went smoothly.

There are two types of alum: for the face potassium alum; for the underarms (not the face) the ammonium alum, but I wouldn't use the latter for either.

I posted in that thread linked to. I have now been using the ammonium based alum for 3+ years without problems. That said the milder potassium based alum might suit more people especially if you have sensitive skin. I will say that I have always had oily skin and suffered from pimples all my life. After using alum post shave the pimples are no longer a problem. Wish I had of discovered that before turning 60.

I have always used the OSMA blocks as the cost was like $8 for 2 big blocks. The only bad part to them is when they slip out of the hand and shatter! Right now I am using an RR one that has a plastic handle. So far so good; no whoopsie yet! Another thing alum works great for is canker sores. Of course, you might want to use a different block; or not.

Absolutely! I bought "The Crystal" stick. Much better to apply than a block as it's in stick form and has a container for travel, although I still have an Omega that I actually use for travel because it's compact. I've used the blocks from the Indian markets, and they work just fine, albeit the texture is rough. At under a buck apiece they make more financial sense than the branded Crystal or Omega, but the format is just much more convenient.
My favorite thing about them is no more crispy armpits in my shirts! WOOHOO!!! =P

I used Crystal Rock Deodorant, for years, before it started to leave a rash. I recently, in the past two weeks, switched to Speed Stick Musk, in combination with Crystal Rock Deodorant Body Spray, for my chest, elbows, and, knees. I think, I may start using it, on my feet, as well.
