Mushrooms are a versatile ingredient, adding an earthy flavour to a variety of dishes. However, they are often still a little dirty when bought, so it's important to know how to clean and store them. The best way to clean mushrooms is a controversial topic, with some saying that washing them will make them soggy, while others claim that brushing them with a damp paper towel doesn't effectively remove all the dirt. Some recommend rinsing them under cool water, while others suggest covering them with cold water and pumping them up and down to loosen the dirt. When it comes to storage, mushrooms should be kept in the refrigerator, with a paper towel to absorb excess moisture, and are best used within a couple of days.

Rinse mushrooms in cool water to remove dirt and insects
When it comes to cleaning mushrooms, it's important to remove any dirt or insects that may be present. While some sources suggest that washing mushrooms can make them soggy, others claim that a quick rinse in cool water is an effective way to clean them. This method is particularly useful if you plan on using the mushrooms in a salad or soup, as any excess water will boil off during cooking.
To rinse your mushrooms, simply hold them under running water to remove any visible dirt and grime. You can do this in a colander, giving them a shake to loosen any dirt, or by holding them in your hand. If the mushrooms still look dirty, you can try a short soak in lightly salted water to draw out any remaining dirt and insects. Change the water as needed, and remember to rinse the mushrooms again afterward to remove any salt.
Once your mushrooms are clean, dry them off with paper towels or a clean kitchen towel. This step is important, as it prevents the mushrooms from becoming waterlogged and helps them to sear properly during cooking.
After rinsing and drying your mushrooms, you may also want to trim the ends of the stems, especially if you're using varieties like shiitake or portobello, which have woody stems that are too fibrous to eat.

Soak in salted water to remove remaining insects and dirt
Soaking mushrooms in salted water is an effective way to remove any remaining insects and dirt. This method is particularly useful for foraged mushrooms, which may be harbouring critters such as springtails, fungus gnat larvae, and slugs/snails.
To soak mushrooms in salted water, start by adding salt to a bowl of water. Use a ratio of 1 tablespoon of salt per 4 cups of water. Swoosh the water with your hand or a spoon to dissolve the salt. Then, add the mushrooms to the salty water and let them soak for a few minutes. For heavily soiled mushrooms, you can soak them for up to 20 minutes. However, if you are soaking more delicate varieties like morels and oysters, limit the soaking time to 5-10 minutes to prevent them from becoming waterlogged and losing their texture.
After soaking, remove the mushrooms from the salty water and drain them in a colander. You may need to repeat the soaking and draining process a second time, especially if your mushrooms are particularly dirty or infested with insects. Once you have removed all the visible dirt and insects, it is important to dry the mushrooms thoroughly. Place the mushrooms on a clean kitchen towel or a layer of cotton dish towels and let them air dry for a few minutes before using or storing them.
While soaking mushrooms in salted water can be an effective cleaning method, it is not suitable for all types of mushrooms. Avoid using this technique on porous mushrooms like Boletes/Porcini or fragile varieties like Shaggy Manes. For these mushrooms, it is better to clean them with a damp paper towel or brush instead of soaking them in water. Additionally, if you plan on pan-frying your mushrooms, it is generally recommended to avoid soaking them in water, as this can affect their texture and make them soggy.

Use a brush or damp cloth to wipe mushrooms gently
When it comes to cleaning mushrooms, a gentle and careful approach is best. Using a brush or damp cloth, wipe the mushrooms softly. This method is ideal for removing any surface dirt or debris without damaging the delicate mushroom flesh. It is a dry cleaning method, which is preferable as mushrooms absorb water if washed.
If the mushrooms are particularly dirty, a brush may be the best tool to start with. Use a soft-bristled brush, such as a pastry brush, and gently sweep away any visible dirt. Pay attention to the crevices and grooves of the mushrooms, as dirt can become lodged in these areas.
If a more thorough clean is required, or if you prefer to use a damp cloth, opt for a soft, absorbent cloth, such as a microfiber cloth. Lightly dampen the cloth with water, ensuring it is not too wet, and gently wipe the surface of the mushrooms. Focus on the areas between the stem and cap, as grime can build up there. You can also use a paper towel, but a cloth may offer a more thorough clean as it can better conform to the shape of the mushrooms.
When using a brush or damp cloth, it is important to be gentle. Avoid applying too much pressure, as this can damage the mushrooms. Work slowly and carefully, wiping or brushing in the direction of the mushroom's surface. This will help ensure that you do not inadvertently tear or bruise the mushrooms.
By using a brush or damp cloth, you can effectively clean mushrooms without compromising their texture or flavour. This method is ideal for preparing mushrooms for cooking, as it ensures they will not become waterlogged, which can affect their cooking properties and impact the final dish.

Store unwashed mushrooms in the fridge in a paper bag or original packaging
It is important to store mushrooms correctly to keep them fresh for longer. Except for morels, mushrooms should be stored unwashed in the refrigerator. Paper bags are ideal for storing mushrooms, and the original packaging is also fine. If you are using a paper bag, ensure the mushrooms are wrapped in paper towels first. Paper bags are breathable, which is important as mushrooms shouldn't be stored in plastic bags.
If you are storing morel mushrooms, clean them and wrap them loosely in damp paper towels or a damp, clean cotton cloth. Place the wrapped bundle in a bowl.
If you are storing mushrooms in a container, line the container with a paper towel and place another paper towel on top. The paper towels will absorb excess moisture and keep the mushrooms fresh for longer.
Mushrooms should be stored in the fridge for up to two or three days. Keep the paper towels damp so that the mushrooms do not dry out.

Wash and place in a container lined with paper towels to absorb excess moisture
If you want to clean and store mushrooms, one method is to wash and place them in a container lined with paper towels to absorb excess moisture. This method is particularly useful if you don't have time to clean the mushrooms thoroughly before storing them.
First, remove the mushrooms from their original packaging. Storing mushrooms in the plastic wrap they often come in will keep them moist, causing them to go bad faster. Then, take a handful of mushrooms and hold them under running water to remove any visible dirt and grime. You can also use a salad spinner to dry them. If you're pan-frying the mushrooms, you can simply rub them down with a damp paper towel or brush them with a pastry brush. However, some sources recommend against using only a brush or paper towel, as this may not effectively remove all the dirt and grime.
After washing, place the mushrooms in a container lined with paper towels. The paper towels will absorb any excess moisture, helping to keep the mushrooms fresh for longer. Place another paper towel on top of the mushrooms before sealing the container.
If you're using wild mushrooms, such as morel mushrooms, they will need to be cleaned differently. For example, morel mushrooms should be submerged in heavily salted water first.
