Review on 👕 16oz Natural Pit Stop: Powerful Sweat Stain & Antiperspirant Stain Remover, Multi-Stain Formula for Armpit Stains by Katie Jefferson

I ordered this because I had a couple of shirts with large pit stains and the reviews were pretty good. I work out in the desert and decided to try this out on a couple of Columbia shirts and regular tops that I wanted to try and salvage. I tried it on a pink 100% cotton shirt, a white synthetic shirt and a white cotton top. I didn't have any dark shirts to try on. I followed the instructions on one of the shirts exactly and didn't bother wiping the others a second time. Not that it matters because all the stains are still there. Some may be a little lighter. Works better with cotton than synthetic, but not by much. Maybe it works best on dark shirts? Others say it can be useful as a preventive measure and if so, the makers of that product should be selling it as such! Not to remove old stains. I'll try again to see if the stains lighten again but am not very impressed with the $15 stain remover. I'll keep looking or I'll end up getting rid of these shirts.
