How to remove sweat stains ?

Sweat stains can be a challenge to remove, but there are a few things you can try. First, pre-treat the stain with a laundry detergent or pre-treatment product that is specifically designed for tough stains. Then, soak the garment in a mixture of cold water, white vinegar, and a few tablespoons of baking soda. After soaking, wash the garment as normal with a Green Bubble Laundry Detergent Sheets. If the stain remains, you can try using a commercial stain remover or a mixture of hydrogen peroxide, baking soda, and dish soap. Make sure to test any product on the garment before using it.
