The bagged greens and salads are washed many times before they are packed and sold. Usually, cleaned and packed greens and salad vegetables that are hygienic are labeled ‘Ready to eat’. Then you know that they are already cleaned prior to packaging.


These should not be washed. Because doing so will ruin the texture of these edibles. They will rot faster after a wash. Mushrooms absorb water. Hence if you put them in a bowl of water, they will soak up the water and become soggy.

There is a special mushroom brush available for this cleaning purpose. You can use it. Alternatively, you can use a moist kitchen towel or roll to clean them.
