Much like vinegar, baking soda is a remarkable cleaning agent for a variety of applications. Thankfully, one of those applications happens to be removing deodorant stains from clothing.
1. Mix three-parts baking soda with one-part water to form a paste.
2. Rub the mixture directly onto the stain.
3. Allow the garment to sit for one to two hours.
4. Launder normally, using hot water.
