I just wanted to share that acid is the ONLY thing that works for me to prevent odor. This started when I heard about Lume deodorant containing mandelic acid, and when I heard about people using Stridex (salycidic acid). I bought the Lume and found that it sorta worked but not 100% so I started using a stridex pad on my pits before applying the Lume. This actually works! Now if you wear an old shirt with BO baked onto it it might stink a bit but newer clothes that I didn't where when I had my BO problem it totally works! I think the acid creates a hostile environment for the bacteria to grow. I really hope this helps someone because it's changed my life!
