Stains occur when the aluminum in your antiperspirant or deodorant combines with the salt in your sweat. The stains are notoriously difficult to get rid of with normal washing in the laundry machine. According to We recommend doing a pre-test on a small area before trying.
Here’s what you need:
- 3% hydrogen peroxide
- Dish soap
- Baking soda
Apply the ingredients directly to the shirt, use an old toothbrush to work them in for a minute, and then let the shirt sit for at least an hour before putting it in the washing machine.
To prevent the stains in the first place, Degree deodorant says it helps to wear loose clothing, make sure your antiperspirant deodorant is dry before you get dressed and don’t use too much product.
