Freaky Armpit Bleach Stains Explained

One of my charming new shirts was ruined by weird beach-like stains from my gel antiperspirant (Yeah, I know. I shouldn't block the sweat. Sweat is nature's perfume. Okay.). This never happened to me before and I don't want it to happen again when I use antiperspirant, so I had to do some research. At first I blamed the shirt maker for using a wimpy dye. But this article convinced me that my gel use was the culprit. It also explains that I don't have to give up the gel if I use it differently.
