"How to Remove Blood Stains from Underwear?"
Blood on underwear can be removed by soaking it in cold water and then washing with soap, or by using specialized laundry products. However, it is important to avoid using hot water to wash the blood off the underwear, as this may worsen the stain and affect the cleaning effectiveness.
1.
When underwear is stained with blood, it can be removed by immediately placing it in cold water and washing with medicated soap. This is because the blood has not yet coagulated, and the iron in heme, which is mainly ferrous iron, is soluble in water. This allows for thorough cleaning of the bloodstain on the underwear.
2.
For older or stubborn bloodstains, they may not be completely removed by cold water washing. In such cases, specialized laundry products should be used to thoroughly clean the underwear. This is because over time, the ferrous iron in heme is oxidized to ferric iron and coagulates with proteins, making it difficult to remove.
3.
Blood contains a high level of protein. If hot water is used to clean bloodstains on underwear, the heat may cause the blood to coagulate, making it more difficult to remove the stain. In daily life, when dealing with bloodstains on underwear, it is important to choose scientifically-based cleaning methods and avoid blindly using unverified remedies.
