How to wash clothes when they are just stained with blood, if you find blood stains, you should immediately wash them with cold water or light salt water (hot water is prohibited, because the blood contains protein, it will coagulate when heated, and it is not easy to dissolve), and then wash with soap or 10% potassium iodide solution. If you find that the blood stains have not completely disappeared, you should put a cloth on the back of the blood stains, spread the blood stains with white radish slices or white radish puree, and then pat it vigorously, or wash it with enzyme washing powder, the effect is quite good, and finally wash it with water.
2. Old bloodstains.
If the blood stains on the clothes have coagulated into stale blood stains, how to wash them, first of all, they should be soaked in cold water for a long time. Because when the blood is not coagulated, the iron in heme is in the form of ferrous iron, which is soluble in water. Over time, the ferrous in the heme is oxidized to ferric iron, which coagulates together with the protein, and it is difficult to wash off the blood spots that form blood spots on the fabric.
You can use enzyme laundry detergent to soak for a long time to remove blood stains between fibers, and the alkaline protease in enzyme laundry detergent can relax, disintegrate, and peel off the protein in blood stains. If it is not clean, wipe the stained area with tartaric acid solution or ammonia (10%), or scrub with 10% 15% oxalic acid solution for 1 2 minutes, because oxalic acid is a reducing agent, which can reduce water-insoluble trivalent iron to water-soluble divalent iron.
