You can remove set-in sweat stains by soaking the clothing in a solution of white vinegar and water, then applying a stain removal paste of baking soda, salt, and hydrogen peroxide to the affected area. Allow the mixture to rest, scrub the stain with an old toothbrush, and machine wash in hot water.
Here are some other methods you can try:
- Soak in a solution of oxygen bleach: This is a good option for deeply set stains. Use a solution of one tablespoon of oxygen bleach per cup of water, and soak for 1-2 hours.
- Use a stain remover: There are many commercial stain removers available that can help remove sweat stains. Follow the instructions on the product label carefully.
- Try a baking soda and vinegar paste: Mix equal parts baking soda and white vinegar to form a paste. Apply the paste to the stain, let it sit for 15 minutes, and then scrub with a toothbrush.
- Use a commercial laundry detergent: Some laundry detergents contain enzymes that can help break down sweat stains. Make sure to use a detergent designed for colored clothes if necessary.
Remember to always check the care label of your clothing before using any stain removal method.
