1. Wash your hands frequently: Generally speaking, if there is a problem of walnut skin dyeing your hands once or twice, you can't achieve a complete cleaning effect. You need to wash your hands frequently for a long time. Wash your hands three times a day in the morning, noon and evening for about three or four days, which can achieve a very good cleaning effect. You can try it.

2. Washing with washing powder: If there is a problem of walnut dyeing hands, washing with washing powder is a very good choice. Washing powder is rough, and friction can also help you to further remove the substances on your hands. Try to use washing powder repeatedly for two or three times to achieve a completely clean effect.

3. Cleaning with baking soda: Walnut skin dyeing hands is to dye an acidic substance on their own hands, and it is difficult to achieve a thorough cleaning effect by cleaning with ordinary water. You can use baking soda to soak in water for cleaning, and acid-base neutralization is also beneficial to remove the dirty substances on your hands. However, the concentration of baking soda water should not be too heavy, otherwise it will hurt your skin.

4. Wash with hand sanitizer: Cleaning with hand sanitizer is also a very good choice. Cleaning with hand sanitizer can not only help you remove black substances, but also help you achieve a beauty and skin care effect and improve your rough hands. There are also many benefits for your own skin.
