Some people use dishwashing detergent to wash fruits. If rinsed with tap water is not thorough enough, it is easy for detergent to remain in the stomach, and its long-term accumulation can be harmful to health.
When washing fruits, you can choose to use salt. For example, after wetting an apple with water, put a little salt on its surface, then hold the apple with both hands and rub it back and forth gently. The dirt on the surface will be cleaned off quickly. Then rinse it with water, and it can be eaten with peace of mind. The principle of this cleaning method is to use the granular state of salt to increase friction, and salt is also very clean.
Additionally, applying toothpaste to the surface of an apple as a cleaner is also a very effective method. Washing apples with hot water is also a good way, as it easily removes preservatives and other substances from the apple's skin. The fruits washed this way can be eaten with peace of mind.
