Your crisp white dress shirt or favorite tee certainly don’t look like they did when you purchased them and when they start yellowing around the collar or under the arms, don't sweat. No matter how nice they are when you purchase them they will probably eventually get a stain under the armpits, which can be quite nasty. The main cause of these yellow stains is sweat combined with body oils and deodorant build-up or how aluminum-based antiperspirants react with the your body. The combination of this sweat and body oil seeps into the fibers of your t/shirts as soon as you start to sweat. It can eventually affect your shirts even if you wear undershirts.
