The Science Behind Pit Stains

Armpit stains on clothes are caused by a combination of sweat and antiperspirant or deodorant. When we sweat, our body releases a fluid that contains water, salt, and other dissolved substances. When this fluid comes into contact with antiperspirant or deodorant, which often contains aluminum and other compounds, it can cause a chemical reaction that results in a yellow or white stain on the fabric. The stain is difficult to remove because the aluminum and other compounds in the antiperspirant or deodorant can bond with the fibers in the fabric.
