How to Remove Sweat Stains
Yellow sweat stains form when the proteins in perspiration react with aluminum compounds found in many antiperspirants. These stains build up over time and can become permanent if left untreated. A paste of baking soda, hydrogen peroxide, and dish soap is one of the most effective home remedies.

Let it work
Leave the paste on the stain for 30 minutes to an hour. For severe stains, extend to 2 hours.

Use an old toothbrush to work the paste into the fabric with gentle circular motions.
