How can traditional blackening replace whitening?

In winter, people put on thick clothes, but black coats and white sweaters are always a classic match, but some people will start to turn black or yellow after wearing white sweaters for a long time. Don't worry about this situation. These three methods can make the white sweater as white as before.

The first method is freezing. In fact, clothes nowadays contain a lot of fiber, especially sweaters. Then after each washing, it may shrink or turn yellow or even black when it is dry. This situation is caused by the chemical composition in the clothes. So after washing the sweater, you can empty the water inside, then put it in the refrigerator and freeze it directly when it feels almost the same. If you have time, you can leave it for an hour, then take it out to dry the white sweater and restore its original color.

The second method is to use rice washing water or orange peel. Like rice washing water and orange peel, it has the function of decontamination. If it is used for washing clothes, there is no problem, and the effect is very remarkable. So if we use washed rice to wash sweaters, we can soak them directly, then wash them normally after a while, and when they are dry, they will become the original color; If you use orange peel, you should boil it first, so as to stimulate the function of orange peel, and then wash clothes.

The third method is to use lemon juice. Lemon contains a special substance, namely citric acid, which can decontaminate and has an effect on everything, so you can directly add a few drops of lemon juice to the basin and soak it for a while before washing it, so that the washed white sweater will be really clean and the color will become very bright.
