How to wash off menstrual blood

How to wash off menstrual blood

Menstruation is a condition that every girl will experience, and basically the amount of bleeding during menstruation is relatively heavy. Sometimes forgetting to change the sanitary napkin or not changing the sanitary napkin in time may cause menstrual blood to get on the pants. Some people don’t know how to wash the menstrual blood, so they just throw the clothes into the washing machine. In this way, the menstrual blood cannot be washed clean from the clothes. So how to wash the menstrual blood?

1. How to clean fresh blood stains on clothes: How to clean clothes when they are just stained with blood. If you find blood stains at this time, wash them immediately with cold water or light salt water (hot water is forbidden because blood contains protein, which will coagulate when heated and is not easy to dissolve), and then wash with soap or 10% potassium iodide solution. If you find that the blood stain has not completely disappeared, you should place a cloth on the back of the blood stain, spread white radish slices or white radish paste on the blood stain, and then pat it hard. Or you can use enzyme laundry detergent to wash it, which is quite effective. Finally, rinse it with clean water.

2. Tips for cleaning old blood stains: If the blood stains on the clothes have solidified and become old blood stains, how to clean them? First, you should soak them in cold water for a long time. Because when the blood has not coagulated, the iron in hemoglobin exists in the form of ferrous iron and is soluble in water. Over time, the ferrous iron in hemoglobin is oxidized into ferric iron and coagulates with protein, forming blood stains on fabrics that are difficult to wash off. You can use enzyme laundry detergent to soak for a long time to remove blood stains between fibers. The alkaline protease in the enzyme laundry detergent can relax and disintegrate the protein in the blood stains and peel it off the fabric. If it is still not clean, wipe the stained area with tartaric acid solution or ammonia water (10%), or scrub it with 10% to 15% oxalic acid solution for 1 to 2 minutes, because oxalic acid is a reducing agent and can reduce water-insoluble trivalent iron to water-soluble divalent iron.

3. Precautions when cleaning blood stains: Whether it is a new stain or an old stain, it can be cleaned by rubbing with sulfur soap. It is not difficult to wash blood stains from clothes, but if not handled properly, they will leave stains. First of all, you need to see how long the bloodstain has been on the clothes. If it is fresh blood, wash it with cold water and then use detergent. Avoid using hot water at this time, otherwise it will leave stains that are difficult to deal with. If the bloodstain has been there 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 inevitably leave marks.
