If the spot gets stuck, blood stains can become a real problem. The best thing to do before a bloodstain is dried is to keep the blood spot under cold water and prevent it from getting stuck – this is one of the best methods to get you to save the fabric. Early intervention of blood stains will definitely help. If the blood is dry without the opportunity to interfere with the stain, you should try to keep the fabric under water first. Then you can try applying a detergent mixture, using a little water and a little ammonia, and then again under water to check if the stain leaves.
