Dry cleaning method 1: You can wash your hands with vinegar. When you get wet, start rubbing your hands. It is best to stop rubbing your hands after they feel warm. Then, after standing for a few minutes, soak your hands in soapy water prepared in advance. After a few minutes, rub your hands.
Dry cleaning method 2: Is there a clean collar at home? If there is, it can also be cleaned with a lead net. The neck net has the function of bleaching, and the black color can be quickly removed by using the bleaching principle.
Spray the collar evenly on the black part, rest for a few minutes, and then clean it with water.
This will hurt your hand. When you're done, apply some hand cream.
Dry cleaning method 3: There is also the simplest method: washing clothes. Soak a big pot of clothes, and then start washing clothes, because washing powder keeps rubbing hands and water. After washing clothes, you find that the juice that is basically black has been washed clean.
Dry cleaning method 4: because it is harmless to the body itself, if you don't care too much, you can wait for the black print to disappear naturally. Pay attention at ordinary times, wash your hands frequently, eat more fruits and vegetables and exercise more. Slowly, these traces will naturally disappear.
Precautions: The juice of green husk will lead to skin ulceration when spilled on the skin outside the hands, because the green husk of walnut is also called "Qinglongyi" and the juice is highly toxic. Splash into your eyes will hurt your eyes.
Because the green peel covered with walnuts contains walnut green pigment, which is a Chinese medicine ingredient for treating dermatitis, the green pigment is oxidized to black and becomes a stain, which can only be effectively removed with diluted strong acid, but diluted strong acid will burn the skin, so you can only wash your hands often and slowly remove it by metabolism, aging and shedding of epidermal cells of your skin.
