What if the white clothes are black?

Teach you a green method. If you cook eggs at home, leave the eggshells. Then put it in a basin and soak it in hot water for fifteen minutes. Then take it out, soak the white clothes in it and clean them. It will be very white.

If you want to wash it with soap, it will be clean. If you are afraid that it will not be cleaned, first buy a bottle of 84 and pour it into the water, but the requirement is white clothes. If it is a colored dress, don't burn it with 84. Buy a bottle of lottery water for colored clothes and rub it repeatedly in the water, because lottery water can wash clothes of any color, that is, remove color and increase color.
