How can I wash off my aunt?

Women always have a few days of discomfort every month, and it is inevitable that menstrual blood will stick to their underwear and bed sheets, which is very difficult to wash off. Sometimes after washing for a long time there will still be a faint blood stain. So there are still some tricks to wash blood stains off clothes. We all know that blood stains should be soaked in cold water before washing. In fact, there are more than just these tips. How do you wash it afterwards?

1. Rubbing with cold water contains protein in menstrual blood, and washing with hot water will cause the protein to coagulate, making the mark even more difficult to wash off. Therefore, underwear that has just been stained with blood should be washed with cold or warm water.

2. When the blood is soaked in enzyme-added laundry detergent and has not yet coagulated, the iron in the 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 underwear that are difficult to wash off. At this time, you can use enzyme laundry detergent to soak and wash. The alkaline protease in enzyme laundry detergent can loosen and break down the protein in the blood stains, allowing them to be peeled off the underwear.

3. Add salt to the white radish and rub it. Wash the white radish clean, crush it with a stick to extract the juice, pour the radish juice on the bloodstained area of ​​the underwear, sprinkle with salt, and rub it a few more times. The blood stains can be rubbed off quickly.

4. If there are stubborn blood stains on your underwear from a long time ago, you can soak them in warm water with a little bleach for half an hour, then rub and clean them with soap, and finally rinse them with clean water.

Attention! Bleach is very irritating, so wash it several times with clean water.

5. Sodium thiosulfate soaking: You can use 1 part of sodium thiosulfate and 50 parts of water, mix, dilute and dissolve, heat to 35°C, soak the underwear until the blood color disappears, and then wash with water. When rinsing with clean water, soak for half an hour to ensure that no sodium thiosulfate remains.

6. Note: Do not wash underwear with blood stains together with other clothes to avoid cross infection of bacteria. After washing, the underwear should be exposed to the sun for disinfection to avoid any bacteria residue on the underwear.
