Whether or not to rinse mushrooms is a highly debated topic. Some sources claim that mushrooms should not be rinsed because they will absorb water, leading to soggy mushrooms that are difficult to cook. Others argue that rinsing mushrooms is acceptable, provided they are dried thoroughly before cooking, as mushrooms are already high in moisture and do not absorb a significant amount of additional water during rinsing. The type of mushroom and the intended preparation may also influence the decision to rinse or not. Certain mushrooms, such as those with exposed gills, are more delicate and prone to absorbing water, so brushing or wiping them clean is recommended. Ultimately, the decision to rinse mushrooms depends on personal preference, convenience, and the desired cooking method.

Mushrooms should be washed before storing or right before cooking?
There are differing opinions on whether mushrooms should be washed before storing or right before cooking. Some sources recommend rinsing mushrooms right before cooking to avoid excess moisture, which can speed up rotting and prevent browning when cooked. Others suggest that it is unnecessary to wash mushrooms before storing, as they are already high in moisture and will not absorb additional water.
Those who advocate for rinsing mushrooms before cooking recommend using cold water in a colander and then drying them on a clean towel or paper towels. This method ensures that dirt and debris are removed, and the mushrooms are ready for cooking. Some people also use a salad spinner to rinse and dry the mushrooms quickly. However, it is important to avoid submerging mushrooms completely, as it can allow water to get into crevices, leading to water-logged and mushy mushrooms.
On the other hand, some people argue that mushrooms can be rinsed and stored without adverse effects. They claim that mushrooms are already high in moisture and will not absorb significant amounts of water from rinsing. These individuals may choose to rinse their mushrooms and then store them in a paper bag with a damp paper towel to maintain freshness.
The decision to rinse mushrooms before storing or right before cooking ultimately depends on personal preference and the specific mushroom variety. Cultivated mushrooms, for example, are grown in sterile environments and may only require a quick brush to remove any excess compost. In contrast, foraged or wild mushrooms may need more thorough cleaning due to their exposure to dirt and debris.
Additionally, the intended cooking method may influence the decision. If grilling or searing a mushroom, it is preferable to wipe or brush it clean, as the extra moisture from rinsing can affect the texture and flavor. However, for other cooking methods, such as sautéing or roasting, rinsing the mushrooms beforehand may not significantly impact the final dish.

How to clean cultivated mushrooms
There are two types of mushrooms: cultivated and wild. Cultivated mushrooms are grown in sterile environments, similar to science laboratories, with sterilized compost, white coats, and sterile gloves. On the other hand, wild mushrooms are harvested in the wild and may be found growing on the side of a tree, at the base of a tree, or even in your driveway or yard. These are unsterile environments that can host leaves, twigs, pine needles, dirt, and bugs.
When it comes to cleaning cultivated mushrooms, it is important to note that they do not require extensive washing due to the sterile environment in which they are grown. Here is a step-by-step guide on how to clean cultivated mushrooms:
Step 1: Inspect the Mushrooms
Before cleaning, it is important to inspect the mushrooms for any visible dirt or debris. This will help you determine the best cleaning method.
Step 2: Remove Excess Dirt
If there is visible dirt or debris on the mushrooms, you can use a soft-bristle brush, a pastry brush, or a mushroom brush to gently scrub and remove it. You can also use a damp cloth to wipe down the mushrooms and remove any dirt or grime. This method is especially useful if you want to avoid getting your mushrooms too wet.
Step 3: Rinsing (Optional)
If your mushrooms are particularly dirty or you prefer to rinse them before cooking, a quick rinse in cold water is sufficient. Place the mushrooms in a colander and rinse them under cool water. It is important not to soak the mushrooms, as they can absorb too much water and become mushy.
Step 4: Dry the Mushrooms
After rinsing, it is crucial to dry the mushrooms thoroughly. Use a clean kitchen towel or paper towels to pat them dry. You can also use a salad spinner to help remove excess moisture and ensure the mushrooms are completely dry before cooking.
Step 5: Timing
It is recommended to clean mushrooms right before you plan to use them, whether that means cooking or freezing them. This is because exposing mushrooms to excess moisture can speed up rotting and affect their texture.
In summary, when cleaning cultivated mushrooms, start by inspecting and removing any visible dirt with a brush or damp cloth. If needed, give them a quick rinse in cold water, ensuring you don't soak them. Finally, dry the mushrooms thoroughly with a towel or salad spinner, and use them immediately for optimal freshness and texture.

How to clean wild mushrooms
Wild mushrooms are those harvested from the wild, often found growing on or near trees, or even in your driveway or yard. They grow in unsterile environments, so they can be dirty and host to bugs and other critters.
- Clean your mushrooms as soon as you pick them. This will prevent dirt from spreading to other mushrooms in your collection.
- Use a brush to remove any large debris, such as leaves, twigs, and pine needles. You can also use a damp cloth to wipe the dirt off.
- Cut away the dirty or woody base where the mushroom was attached to the ground or wood. Inspect for wormholes and discoloration.
- Break the mushroom into smaller chunks to expose the interior. Remove any remaining sticks or debris.
- Fill a large bowl or your sink with cold water. Plunge the mushroom chunks into the water and swish them around. The dirt will fall to the bottom, and needles or other light debris will float to the top. Remove the clean chunks from the middle. Repeat if necessary.
- Place the cleaned mushrooms in a colander and rinse with cool water to remove any remaining dirt or debris.
- Dry the mushrooms. You can use a salad spinner to remove excess water, then air dry for at least an hour or up to several days until completely dry. Dehumidifiers can speed up this process.
Some people choose to simply rinse their mushrooms under running water before cooking, which is also an effective method. However, wild mushrooms tend to be dirtier and may require a more thorough cleaning process.
Remember to always properly identify wild mushrooms before consuming them, as some varieties can be toxic.

Best ways to clean different types of mushrooms
There are various ways to clean different types of mushrooms, and it is a common myth that washing mushrooms is a bad idea. Here are some of the best ways to clean different types of mushrooms:
Wild Mushrooms
Wild mushrooms, such as chanterelles, often have dirt or grit on them, especially if they have been foraged. It is important to clean them immediately after picking to prevent the spread of dirt. One way to clean wild mushrooms is to fill a large bowl with water, add salt (1 tablespoon per 4 cups of water), and then soak the mushrooms for 20 minutes. This method helps to remove any tiny creatures that may be present, especially during the summer months. After soaking, the mushrooms should be dried thoroughly on a cotton dish towel or in a salad spinner.
Store-Bought Mushrooms
Common store-bought mushrooms like portobello, cremini, buttons, and shiitakes often have a peaty-smelling growing medium clinging to their caps. One way to clean these mushrooms is to use a mushroom brush, which has soft bristles perfect for cleaning delicate mushrooms. If you don't have a mushroom brush, you can use a damp cloth or paper towel to wipe away any dirt. You can also fill a large bowl with water and dunk the mushrooms into it for a quick clean. Make sure to wash them just before using, as unwashed mushrooms last longer in the refrigerator.
Morels
Morels are a type of mushroom that requires special attention when cleaning. It is recommended to halve them lengthwise and then wash the halves in a bowl of water. If you want to keep the morels whole, you can brush them gently with a mushroom brush and then wash them in a bowl of water. After washing, morels should be dried in a salad spinner.
Oyster Mushrooms
Oyster mushrooms, also known as maitake, are very delicate, especially their caps, which tend to break easily. To clean oyster mushrooms, trim their ends and then soak them in water for about five minutes. After soaking, drain them and dry them thoroughly, either with a cotton dish towel or a salad spinner.
While there are various methods for cleaning different types of mushrooms, it is important to note that some people choose to rinse all their mushrooms under water, especially if they look muddy, while others prefer to avoid washing them to prevent the mushrooms from absorbing too much water. Ultimately, the best way to clean mushrooms depends on personal preference and the type of mushroom being cleaned.

Why do people believe mushrooms shouldn't be washed?
Many people believe that mushrooms shouldn't be washed because they will absorb too much water, which will make them difficult to cook and result in a soggy, less flavorful end product. This belief is perpetuated by cookbooks and chefs, who advise against washing mushrooms to avoid diluting their flavor and texture. However, it is important to distinguish between cultivated and wild mushrooms when considering the need for washing.
Cultivated mushrooms, which are grown in sterile environments and compost, are generally clean and only require a quick brush to remove any excess compost. The American Mushroom Institute states that "Mushroom-washing methods have been developed only as a means to enhance appearance and remove mushroom compost flecks, not for food safety concerns." Therefore, a simple brush or wipe with a damp cloth is often sufficient for cultivated mushrooms.
On the other hand, wild mushrooms may require a more thorough cleaning process. If you happen to find a mushroom in your yard, it is essential to do your research to identify whether it is safe to eat. Wild mushrooms can be cleaned in various ways, depending on their variety. Some people opt to scrape or peel the dirt off, while others use a soft-bristle brush or a damp cloth to gently remove visible dirt.
While some believe that washing mushrooms should be avoided altogether, others argue that a quick rinse followed by thorough drying is an acceptable method for cleaning mushrooms. This technique is especially useful for varieties without exposed gills, such as button, cremini, or porcini mushrooms. However, it is crucial to avoid soaking or submerging mushrooms completely, as it can lead to excess moisture absorption, resulting in water-logged and mushy mushrooms.
Additionally, it is recommended to wash mushrooms right before cooking to prevent them from turning slimy. Overall, while there are valid concerns about maintaining flavor and texture, it is possible to wash mushrooms without compromising their quality. The key is to use an appropriate cleaning method, avoid excessive soaking, and ensure proper drying before cooking.
