1. Clothes, sheets, quilt cover, etc., stained with blood, should be cleaned immediately, otherwise the blood spots will not be easily removed.
2. Also, when cleaning bloodstains, do not wash with hot water, only with cold water.
Deliberately did the following experiment: Take two pieces of white cloth and drop a few drops of fresh chicken blood. Soak a white cloth in hot water, and immerse another white cloth in cold water. After a while, take out two white cloths and find that the blood stains soaked in hot water turned dark red, and the blood stained in cold water is still bright red. And the color has become lighter. Take some soap, smear it on the blood of two white cloths, and clean the blood on the white cloth soaked in cold water. The blood stains soaked in hot water cannot be cleaned.
Explain: The blood contains protein components such as plasma that are soluble in water, and when heated, it becomes insoluble in water, just like the chicken blood, pig blood, or eggs that we usually eat. After heating, it becomes a block that is insoluble in water, so it is naturally not easy to wash. By the same token, when blood is exposed to the air for a long time, similar chemical changes will occur. This is the reason why Chen Jiu’s blood is not easy to wash away.
3. Wash the blood stains first with cold water, then wash with enzyme washing powder. Or wash it with soap or 10% potassium iodide solution; or remove the blood on the clothes with white radish juice or chopped carrots; or use 10% tartaric acid solution to wipe the stain and wash it with cold water;
It is very effective to remove blood stains with enzyme washing powder.
4. Old blood can be washed with oxalic acid. It can also be washed with lemon juice and salt water. (Occasionally, it is stale.)
Explain: the old blood stains turned dark brown, because the iron in the hemoglobin was oxidized in the air, producing rust. The juice also contains iron, which is contaminated with oxygen in the air and also produces brown rust spots.
Therefore, the stains caused by blood, juice and rust can be washed with oxalic acid, which turns rust into a colorless substance and dissolves into the water.
5. The blood on the white garment can be diluted with 1 part of sodium thiosulfate and 50 parts of water. After mixing, it is diluted and dissolved and heated to 35 ° C. The white clothes are immersed, the blood color disappears, and then washed with water. The fabric can also be immersed in a 3% vinegar solution, placed for 12 hours, and then rinsed with water, the effect is also very good.
6. Both the new traces and the traces can be cleaned with sulfur saponin.
