You see, mushrooms are like little sponges, and when you wash them, they can absorb a ton of water, making them super soggy and virtually impossible to cook with. It's like trying to cook with a wet sponge - not exactly the most appetizing thing. And trust me, you don't want to end up with a dish that's more like mushroom soup than a savory stir-fry.
But, you might be thinking, what about all the dirt and debris on the mushrooms? Well, most mushrooms are actually grown in controlled environments, so they're pretty clean to begin with. And if you do happen to get some dirty ones, a quick brushing with a soft brush or a dry cloth should do the trick.
