How do you get blood stains out of clothes?

What You Need bowl or sink filled with cold water, bar of soap, stain-removal spray, ammonia, cotton swab, paper towel, laundry detergent Follow These Steps Wet the stain with cold water If the stain is fresh and still wet, soak fabric in cold water immediately. Rub with soap Rub the stain well with a bar of soap, lathering gently. Tip: For light-colored fabrics, dab with a hydrogen peroxide, which acts as bleach. Re-soak the stain with a pre-treatment stain remover If the stain has already dried, spray with stain-removal solution. Let it soak in. Dab on diluted ammonia Apply a small amount of diluted ammonia to the area with a cotton swab. Launder fabric Machine-wash the fabric using an enzyme detergent (most standard laundry soaps are enzyme-based), which breaks down protein stains. Make sure the blood has lifted before putting fabric in the dryer, as the heat will set the stain.
