To remove sweat stains from hats, pre-treat the stain with a paste of 4 tablespoons of baking soda and ¼ cup of cool water, scrubbing the mixture gently into the stain and/or sweatband with a soft toothbrush. Let the mixture sit for 1-2 hours, then rinse and hand-wash the hat with water and a mild detergent.
