How can the blood on the clothes be washed clean
1. Tips for cleaning Chen's blood stains for a long time
If the blood stains on the clothes have solidified into old blood stains, how to wash them? First, soak them in cold water for a long time. Because when the blood is not coagulated, the iron in heme exists in the form of ferrous and can be dissolved in water. Over time, the ferrous iron in heme is oxidized into ferric iron and coagulates with protein. It is difficult to wash off the blood spots formed on the fabric. You can use enzyme detergent to soak for a long time to remove blood stains between fibers. The alkaline protease in enzyme detergent can relax and disintegrate the protein in the blood stains and peel it off from the fabric. If it is not clean, wipe the contaminated part with tartaric acid solution or ammonia (10%), or scrub it with 10% ~ 15% oxalic acid solution for 1 ~ 2 minutes, because oxalic acid is a reducing agent, which can reduce trivalent iron insoluble in water to divalent iron soluble in water.
