What is the best way to remove blood stains?
Soak in COLD salty water. Just add a handful of salt to water and soak overnight. The stain will be gone. Fresh blood stains can usually be removed by a thorough laundering in cold water. If any stain remains, soak it in a solution of 1 quart WARM water, 1/2 teaspoon dishwashing or liquid laundry detergent, and 1 tablespoon ammonia for 15 minutes. Tamp (the method of bringing a brush down with light strokes on stained durable fabrics and materials) or scrape (the method of using a scraping tool to gently lift off excess solid or caked-on stains), blotting occasionally with an absorbent pad. Continue as long as any stain is being removed. Rinse well with water, making sure to remove all traces of the ammonia. Then dry or launder.
