I\'m 14 an was told that aluminum free deodorant would stop yellow stains on my white shirts, so which female deodorant would help stop yellow stainsAluminum salts are used in antiperspirants. So, skip anything that claims to be an antiperspirant. (Some things that are antiperspirants are sold as deodorants, but not the other way around.) Right Guard Sport spray does not contain aluminum salts, and my T-shirts stayed white after I switched to it. Many people mistakenly think that it is the sweat that discolors the armpits.Deodorant with aluminum also causes breast cancer. I use Toms of Maine deodorant, which is aluminum-free.Other related question
