In daily life, in addition to inadvertently stained with various oil stains, sometimes stained with blood stains, which is very difficult to clean, if the time is too long, it is very easy to wash. Today, Xiaobian is going to teach you how to wash the blood stains on your clothes.
1. Cleaning method of fresh blood stains on clothes
When the clothes are just stained with blood, how to wash them? In this case, if you find blood stains, wash them immediately with cold water or light salt water (hot water is forbidden, because the blood contains protein, it will coagulate in case of heat, and it is not easy to dissolve), and then wash them with soap or 10% potassium iodide solution. If it is found that the blood stain still hasn't disappeared completely, cloth should be placed on the back of the blood stain, slice the white radish or spread the white radish mud on the blood stain, then pat it hard, or wash it with enzyme washing powder, the effect is quite good, and then wash it with water.
2. The cleaning tips of old blood stains with a long time
If the blood stains on the clothes have coagulated 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, which can be dissolved in water. For a long time, the ferrous iron in heme is oxidized to trivalent iron, and coagulates together with protein, so it is difficult to wash off the blood spots on the fabric. The blood stains between fibers can be removed by long-time soaking with enzyme detergent. The basic protease in enzyme detergent can relax and disintegrate the protein in the blood stains and peel off the fabric. If it is not clean, wipe the contaminated area with tartaric acid solution or ammonia water (10%), or scrub it with 10% - 15% oxalic acid solution for 1-2 minutes, because oxalic acid is a reducing agent, which can reduce the insoluble iron to the soluble iron.
3. Precautions for cleaning blood stains
Both new and old traces can be rubbed and cleaned with sulfur soap. It's not hard to wash the bloodstain on the clothes, but if it's not handled properly, it will also leave spots. First of all, it depends on the time of the blood on the clothes. If it's fresh blood just touched, wash it with cold water and then use washing powder. At this time, do not use hot water, or it will leave marks that are difficult to handle. If it's blood that has been left for a long time, soak it in cold water for two or three hours, and then rub it with lemon juice and salt. Once hot water is used, it will leave traces.
