Generally, persimmons do not need to be washed before eating.
Some people may think that the white powder on the persimmons is dust or mold and needs to be washed off before eating. In fact, the white powder is the persimmon frost, which is also the sugar in the persimmon. If you wash it off, the sweetness will be greatly reduced. The white frost is the nutritional essence of the persimmon, and it is definitely edible. There is no need to wash it off. If you wash it, it will affect the taste and value of the persimmons.
Recommendations
Whether you should wash the persimmons before eating depends on whether the persimmons themselves are hygienic. Generally speaking, bulk persimmons are more likely to have hygienic problems. Generally, try to buy as few persimmons as possible, and there is nothing wrong with washing them before eating.
But if the persimmons are in sealed packaging, there is usually no need to wash them. The principle of “you get what you pay for” also applies to persimmons.
