How to deal with hands dirty by walnuts

The main reason why walnuts make your hands dirty is that the walnut skin contains zeaxanthin. Because of the presence of zeaxanthin, your hands turn black after the walnut skin is broken. In fact, turning black does not happen all at once. It requires a process. When people get their hands on melanin, melanin will be oxidized in the air and turn black. This is the final result that people feel their hands are dirty. So what should you do if you get your hands dirty while cleaning walnuts?

First, let me introduce walnut peel, which is a traditional Chinese medicine ingredient for the treatment of dermatitis. It is extracted from the green peel of walnuts and contains substances such as tannin (i.e. tannic acid) and gallic acid. It turns black after being oxidized and is most suitable for use as a colorant in hair dyes.

Currently, the only method that can quickly remove the black color caused by oxidation discoloration is diluted strong acid, such as dilute sulfuric acid.

If the skin is stained with black oxide of walnut green peel element, you can only wash your hands frequently and rely on the body's own skin epidermal cells to metabolize, age and fall off to slowly remove it.

For newly stained fruit juice, sprinkle some salt first, gently moisten it with water, and then wash it in soapy water. For minor fruit stains, wash them with cold water. If they cannot be completely washed off in one wash, wash them again until they are completely washed. If the contamination is more serious, you can use dilute ammonia water (1 part ammonia water to 20 parts water) to neutralize the organic acid in the juice, and then wash it with soap. Woolen clothes can be washed with tartaric acid solution. Silk can be scrubbed with citric acid or soap or alcohol solution. Drop a few drops of vinegar on the juice stains, rub them with your hands several times, and then wash them with clean water.
