Baseball uniforms, especially the pants, require intensive cleaning to keep them sparkling clean. Red clay clings to the fibers of baseball pants like mud, creating a laundry dilemma about how to extract the red sludge from the fabric. Allowing the red dirt to dry before removing it from the pants helps to keep the stain from spreading to other areas of the fabric.
Brush dried red dirt from the baseball pants with your hand. Take the pants outside or brush them over a trash can.
Pour 4 tbsp. of liquid laundry detergent into a bowl. Stir 2 tbsp. of baking soda into the detergent. Add more baking soda, if needed, to make a thick paste.
Spoon the detergent mixture onto the red dirt stains on the pants. Grasp the pants on each side of the stain, and rub together to force the stain remover into the fabric. Allow the detergent to remain on the stains for 30 minutes before washing.
Place the pants into the washer and set the water temperature to warm. For white baseball pants, add 1/4 cup of chlorine bleach to the wash water, and 1/4 cup of all-fabric bleach to colored baseball pants. The detergent stain remover mixture placed on the pants previously is enough to clean the clothing without adding more laundry detergent.
Examine the stains after removing the pants from the washer. If the stains remain, repeat the cleaning process again, starting with the laundry detergent and baking soda paste.
