How to clean the yellow stain on the white quilt?

How to wash the white sheets when they turn yellow? 1. Rinse with bleach. It is best to add some white vinegar to the rinse water, so as to keep the true color of white silk fabrics and effectively prevent white sheets from turning yellow. 2. When there are stubborn stains on the white sheets that are difficult to remove, boil a slice of lemon and soak the white sheets in water for about 15 minutes before cleaning. 3. Turn the sheets upside down when drying them. The bottom of the sheet faces the sun and the top has a shadow. 4. Add hydrogen peroxide to the washing water of white sheets. 3% hydrogen peroxide can be used for bleaching silk and wool fabrics, and the liquid volume is 10 times of the weight of the fabric. Then add a little ammonia water to make them weakly alkaline, soak them for 5- 10 hour, then wash them and dry them. 5. If it is a white sheet made of man-made fiber, add some salt to the water when cleaning it. If it is some advanced materials, adding a small amount of alum to the plate can avoid fire and reduce the yellowing and fading of the plate.

6. If there is more dirt on the white sheets, you can clean them with radish soup. After washing, you will find the sheets as clean as new. 7. Drop 3-5 drops of pure blue ink into a basin of clean cold water. After stirring by hand, put the cleaned white sheets into water, then stir them up and down for 3-5 times, and then take them out to dry. 8. When washing white sheets, you can also soak them in skim milk, or add 2 tablespoons of milk to the water during the last rinse, so that the washed sheets are not easy to turn yellow.
