How to wash off the blood stains on the quilt? Find a specific method.

1. Wash clothes and sheets with toothpaste.

This method is best used only on clothes that can be washed thoroughly by washing machine or hand. If you use toothpaste on carpets or large furniture, you may never get rid of the smell of toothpaste.

2. Clean the solid cloth with tender meat powder.

Blood and meat are organic substances, which can react with protease, cellulase and lipase. The raw tender meat powder sold outside is very effective in cleaning dry blood stains.

3. Detergents, dishwashing agents and the like all contain these enzymes.

This method is suitable for cleaning strong fabrics such as jeans, but not for cleaning delicate fabrics. Do not use enzymes to clean linen, silk and wool clothes. These products containing enzymes will decompose protein, thus destroying linen, wool and other fabrics containing protein.

4. Wash delicate fabrics with saliva.

Saliva can also effectively remove blood stains, because the enzymes in saliva that help digest food can also decompose protein in blood, and it is these protein that make blood stains difficult to remove. Note that this method is only applicable to very small blood stains.

Step 5 Wash with oxalic acid

You can also wash it with lemon juice and salt water. Old blood turns dark brown because the iron in hemoglobin is oxidized in the air, resulting in rust. Fruit juice also contains iron, which will also produce brown iron rust spots when it comes into contact with oxygen in the air.

Therefore, stains caused by blood, fruit juice and rust can be washed off with oxalic acid, which turns rust into colorless substances and dissolves in water.

Step 6 wash with laundry detergent

When the sheets are dry, wipe up the blood stains with special laundry detergent. Let it stand for 5 minutes, rub the blood spot and wash it regularly.

If it is stubborn blood, wring out the bed sheet, stick the blood spot on the bottom of the basin, clean it with colored clothes and the collar of 1/4 bottle cap (10g), pour it on the blood spot, and cover the blood spot with other parts of the bed sheet to prevent air drying. Stand in the dark for 2 hours. If the blood is still not removed after two hours, add an appropriate amount of water to wet the sheets and leave them overnight.
