1, sprinkle some salt: you can sprinkle some salt first, gently moisten it with water, and then soak it in soapy water to wash it, which has a certain effect on slightly blackening your hands. If you wash it several times, it will gradually fade.

3. Wash with vinegar: When the black on your hand is dry, you can also wash it with vinegar and then wash it with water, so you can wash the black.
Method of selecting walnuts
1, look at the pattern of walnut skin: when we choose walnuts, we can see that some walnut patterns are deeper and some walnut patterns are lighter. The depth and number of walnut patterns can help us to select good quality walnuts. Walnut pulp with deep patterns is relatively thin, and after drying, the pulp is basically gone. Walnuts with shallow patterns are walnuts with full flesh. Therefore, we choose walnuts with more patterns and shallower patterns, so that the walnut pulp is full.
2, feel the weight of walnuts: when you choose walnuts, you are always easily confused by the size of walnuts, and feel that there are more walnuts that grow bigger. In fact, this is not necessarily the case. There are some big walnuts with less pulp. If you want to tell whether the pulp inside the walnut is full or dry, you can pick it up and feel the weight. All things being equal, the heavier walnut means that it is a walnut with full flesh, so it can be purchased with confidence.
3, look at the color of walnuts: most walnuts are basically khaki, but when you choose walnuts, you see some walnuts with white colors and white powder on the surface, don't buy them. Walnuts with white powder may be walnuts bleached with bleaching powder. If the skin of this walnut breaks, the bleaching powder will enter the pulp, which will do some harm to the body when eaten. Moreover, the pulp with bleaching powder has changed its taste, and its taste is not as good as it used to be.
