What to do if menstrual blood cannot be washed off

I believe many women have experienced the situation of menstrual blood stained on their underwear, and most menstrual blood is quite stubborn, so it is not easy to wash it off thoroughly. It would seem a pity to throw away a pair of underwear if it is not washed clean, so many women will come up with many ways to wash away menstrual blood. However, it is generally very difficult to wash off women's menstrual blood on their underwear. So what should you do if the menstrual blood on your underwear cannot be washed off?

1 How to wash menstrual blood from underwear - wash with cold water

Many people's first reaction when their underwear is stained with menstrual blood is to soak it in hot water, thinking that this is the only way to clean it. In fact, this practice is wrong, because menstrual blood contains a certain amount of protein. If you use hot water to wash it, it will cause the protein in the menstrual blood to coagulate, which will make it even more difficult to wash clean. Therefore, you must use cold water to wash it.

2 How to wash menstrual blood from underwear - washing with hydrogen peroxide

Hydrogen peroxide can easily wash off menstrual blood stains on underwear. Just wet the underwear, then pour a little hydrogen peroxide on the blood stains, and rub them appropriately to easily wash off the blood stains. However, hydrogen peroxide is not common in our lives and you have to buy it at a pharmacy.

3 How to wash off menstrual blood on underwear - soak with enzyme washing powder

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 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.

4 How to wash off menstrual blood on underwear - sulfur soap cleaning

We often have one or two pieces of sulfur soap at home. In addition to sterilization, sulfur soap can also easily wash away menstrual blood on underwear. Using sulfur soap, no matter the blood stains are just now or a few days ago, they can be washed clean. However, the underwear must be rubbed slowly to wash them clean, so you must be patient.

5 How to wash off menstrual blood on underwear - soak in bleach

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. It should be noted that bleach is very irritating, so you need to rinse it several times with clean water after washing.

6 How to wash off menstrual blood on underwear - Sodium thiosulfate soaking

You can use 1 part sodium thiosulfate and 50 parts water, mix them, dilute and dissolve them, heat them to 35°C, soak your 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.
