Getting Rid of Armpit Stains

I really wish I could have gotten a better picture of my shirt after I did this little trick because it worked really well.  I have a white shirt that I wear a lot as an undershirt and it did such an awesome job at getting rid of the armpit stain on my shirt.  I love it when people come up with such great solutions for our everyday problems.
Add 1/4 Cup Hydrogen Peroxide with 1/4 Cup Baking Soda, scrub with toothbrush or some sort of bristle brush, let sit for 1/2 hour and then wash like normal.
