I agree with Ryan. Some people argue that it's sweat, not the aluminum based compound in anti-perspirants that create the stain.

Here is a list of possible solutions. I'd try the peroxide or boric acid first.
If you are a heavy sweater like I am, I have been prescribed a steriod type drug that you apply at night 1 or 2 times a week and it can work up to 2 weeks! The only thing you need then is deodorant to cover b.o.
