Everyone must want to know how to wash blood stains on clothes. Let's find out together.

If you find that the blood stain has not completely disappeared, you should put a cloth on the back of the blood stain, spread white radish slices or white radish paste on the blood stain, then pat it hard and then wash it with clean water. Clothes stained with blood should be washed immediately in cold water. 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. Therefore, as soon as blood stains the surface, you should immediately wash it with cold water (never use hot water, because blood will coagulate when it comes into contact with heat), and then wash it with soap or 10% potassium iodide solution to remove it.
