How to clean the blood stains on the sheets?

1, cold water flushing. After the sheets are stained with blood, don't throw them into the washing machine in a hurry, but take them under the tap and wash them with cold water first. Why use cold water instead of hot water? In the eyes of many housewives, hot water is easier to dissolve and remove stains. This is because the blood contains protein, and protein will solidify when heated. Once solidified, it will become tricky and increase the difficulty of cleaning. So be sure to wash it with cold water. After the blood stain is diluted, put the sheets in the washing machine.

2. Use enzyme washing powder. A large number of enzyme preparations, such as cellulase and alkaline lipase. Add to washing powder with enzyme. These enzyme preparations are rich in enzymes, which can destroy the protein structure in blood and dirt, decompose protein into soluble peptide bonds, and then decompose peptide bonds into amino acids, so that blood stains and dirt on sheets can be easily washed off. When using enzyme-added washing powder, we should pay attention to the water temperature of 40℃, and the highest temperature should not exceed 50℃, otherwise the enzyme in washing powder will be killed and the decontamination ability of washing powder will be reduced.

3, hydrogen peroxide treatment of blood stains. If there are a lot of blood stains on the sheets, it is best to treat the blood stains with hydrogen peroxide before machine washing. When hydrogen peroxide is poured on the blood stains on the sheets, it will react with the blood, making the blood stains almost invisible or even completely disappear. After half an hour, wipe off the residual foam on the sheets with a rag, and then go into normal hand washing or machine washing, remember to wash with cold water! Pay attention to shading when treating blood stains with hydrogen peroxide, because strong sunlight will promote the decomposition of hydrogen peroxide into water. In addition, if hydrogen peroxide is used to treat blood stains on expensive clothes, it is best to dilute them with water first.
