A lot of people in the cleaning of mushrooms, the habit of hand scrubbing a few times to stop, so although the surface clean, but the folds of the sediment and formaldehyde has not been washed, some of the sediment will also be scrubbed because of the method of adsorption in the folds of the fungus again. Therefore, when cleaning mushrooms, use a few chopsticks to stir the water in one direction, then the mushrooms in the sediment will be stirred with the direction of the water flow and fall down, repeated stirring a few times, you can wash the mushrooms clean.
Another method is to first rinse the mushrooms with water to get rid of all the surface soil, and then use two spoons of salt in water to soak the mushrooms for about 15-20 minutes. After that, until the salt is fully dissolved in the mushrooms, you can use your hands to scrub them clean. After this step, you can use the previous method to clean them with chopsticks in one direction, and after scrubbing the mushrooms, you can finally rinse them again with clean water.
