How to clean blood stains on clothes

Whether in daily family life or in service industries such as laundry shops, you need to master some practical skills. For example, to remove blood stains from clothes or sheets in life, you need to master some essentials. Fresh blood stains or old blood stains must be removed by different methods. The following methods will keep your clothes clean and new while removing blood stains. If you need it, you can understand and adopt it.

Clothes, bed sheets, quilt covers, etc., stained with blood, must be washed immediately, otherwise the blood stains will be difficult to remove over time. .And when cleaning blood stains, do not use hot water, only cold water. To clean blood stains, first soak them in cold water and then wash them with enzyme laundry detergent. Or wash with soap or 10% potassium iodide solution; or use white radish juice or mashed carrots mixed with salt to remove blood stains on clothes; or use 10% tartaric acid solution to wipe the stained area, and then wash with cold water; using enzyme laundry detergent to remove blood stains is very effective.

Old blood stains can be removed with oxalic acid. You can also wash with lemon juice and salt water. Old bloodstains turn dark brown because the iron in the hemoglobin is oxidized in the air to form rust. Fruit juice also contains iron, which can form brown rust stains on clothes when it comes into contact with oxygen in the air.

I specially did the following experiment: take two pieces of white cloth and drop a few drops of fresh chicken blood on each of them. Soak a piece of white cloth in hot water and another piece of white cloth in cold water. After a while, take out the two pieces of white cloth and find that the bloodstains soaked in hot water have turned dark red, while the bloodstains soaked in cold water are still bright red, and the color has also become lighter. Take some soap and rub the blood stains on the two pieces of white cloth. Use the white cloth soaked in cold water to clean the blood stains thoroughly. However, blood stains soaked in hot water cannot be cleaned.

To explain: The blood contains protein components such as plasma which can dissolve in water, but after being heated, it becomes insoluble in water. It is the same as the chicken blood, pig blood, or eggs we usually eat. After heating, it turns into a lump that is insoluble in water, which makes it naturally difficult to wash clean. By the same token, similar chemical changes will occur when blood stains are exposed to the air for a long time. This is why old blood stains are difficult to wash off.

In fact, in life, many people use enzyme laundry detergent and sulfur soap to remove blood stains. It is very effective in removing blood stains, but this method still requires continuous scrubbing. What needs to be noted is to keep the clothes in their original appearance during scrubbing and not to use brute force. That will make the clothes look uglier, and the above methods are relatively effective.
