Sweat
Strange as it may seem, not all antiperspirants protect you from sweat stains on your clothes. You will be glad to learn that such stains are easily removed.
- Mix some dishwashing liquid (1 teaspoon) with hydrogen peroxide (3-4 teaspoons) and soda (2 teaspoons). Apply the blend to the stain, wait a bit, and then rinse with water.
- You can also use vinegar and hot water to remove such a stain.
