Mushrooms are a versatile ingredient, but they can be a hassle to prepare, which is why some stores sell prewashed mushrooms. However, opinions vary on whether prewashed mushrooms are truly prewashed and if they need to be washed again before cooking. Some sources claim that prewashed mushrooms are dry-washed, and the final wash before use is unnecessary. Others argue that mushrooms should always be cleaned before cooking, and some recommend using a damp paper towel or a quick rinse to remove any dirt or debris. Ultimately, it is up to the consumer to decide whether to wash prewashed mushrooms, but it is important to handle mushrooms properly to ensure they remain fresh and safe to eat.

Prewashed mushrooms are often dry-washed, requiring a final wet wash before use
Mushrooms are typically washed by gently wiping them with a damp paper towel or clean kitchen cloth to remove any dirt. This method is often used for mushrooms with less visible dirt. For mushrooms with more dirt, such as foraged mushrooms, it is recommended to rinse them with cold water and then dry them with a paper towel.
Some people believe that washing mushrooms will make them soggy and affect their texture and taste. However, others argue that this is a myth, as mushrooms do not absorb much water. It is generally recommended to wash mushrooms just before cooking to avoid sogginess and maximise freshness.
When it comes to prewashed mushrooms, some people still choose to give them a final wet wash before use, especially if they plan to cook them immediately. This ensures that any remaining dirt or bacteria is removed, making them safe to consume.

Mushrooms grown in manure or rotting wood are best washed before cooking
Mushrooms are cultivated in a heat-treated compost that is practically sterile, removing common plant pathogens like mold, bacteria, viruses, worms, and bugs. Commercially produced mushrooms are grown on sterile manure, which is safe to eat. However, it is still recommended to clean mushrooms before cooking to remove any remaining dirt or grit, which can ruin a dish.
Mushrooms grown in manure or rotting wood, such as button mushrooms, are best washed before cooking. Wild mushrooms, like chanterelles or black trumpets, are often full of forest debris, including bugs, wood chips, and pine needles, and require a thorough rinse. For varieties with exposed gills, such as oyster mushrooms, portobellos, and shiitakes, it is recommended to use a dry cleaning method with a paper towel, pastry brush, or mushroom brush to remove dirt without absorbing excess moisture.
Button, cremini, or porcini mushrooms, which do not have exposed gills, can be rinsed in cold water and dried with a paper towel before cooking. This ensures the removal of any dirt or compost without affecting the quality of the mushroom. It is important to note that mushrooms should be washed right before cooking, as washing increases the chance of them becoming slimy, moldy, or rotten.
While some sources advise against washing mushrooms, claiming it affects their texture and browning ability, others refute this idea, stating that mushrooms do not absorb water. The decision to wash mushrooms grown in manure or rotting wood ultimately depends on personal preference and the desired level of cleanliness. However, it is generally recommended to at least brush off any visible dirt or debris before cooking.

Mushrooms can be washed by rinsing them in a colander and drying them with a paper towel
While there is some debate on the best way to clean mushrooms, rinsing them in a colander and drying them with a paper towel is a quick and effective method. Mushrooms are delicate, with a high moisture content, so it is important to handle them with care when rinsing.
To start, place the mushrooms in a colander and give them a quick rinse with cold water. Shake off any excess water and then gently pat them dry with a paper towel or a clean kitchen towel. It is important to remove as much moisture as possible to prevent the mushrooms from becoming slimy. This method is particularly useful if your mushrooms have visible specks of dirt on them.
For a gentler approach, you can fill a large bowl with cold water and add a few mushrooms at a time. Swirl them around in the water for about 10 seconds to loosen any dirt, then remove them to a towel. Pat the mushrooms dry and lay them out to air-dry completely before cooking.
If your mushrooms are particularly dirty, you may want to try a different cleaning method first. For foraged mushrooms, professional forager Alexis Nikole Nelson recommends dunking and scrubbing them in a bowl of water and vinegar before giving them a final rinse. You can also use a mushroom brush or a soft toothbrush to remove stubborn dirt.
While some people believe that washing mushrooms will make them soggy and affect their cooking, others argue that mushrooms do not absorb much water and can be safely rinsed. However, it is generally recommended to clean mushrooms just before cooking, as washing them too far in advance can lead to spoilage.

Mushrooms can also be cleaned with a damp paper towel or kitchen towel
While some grocery stores do sell prewashed mushrooms, it is not a common practice. This is because getting prewashed mushrooms wet can make them slimy. Hence, it is recommended to give them a final wash before use.
Mushrooms can be cleaned in several ways, and one of the most popular methods is to use a damp paper towel or a kitchen towel. Chef Sara Moulton, host of the PBS series "Sara's Weeknight Meals," recommends wiping each mushroom with a damp paper towel. While this method can be time-consuming, it is effective and gentle on the mushrooms.
If you prefer a quicker method, you can try the technique Moulton learned while working at a restaurant in France in 1979. Fill a bowl with cold water, add about six mushrooms, swish them around while counting to ten, and then remove them from the water. This process will cause any dirt or compost clinging to the mushrooms to fall off, and the mushrooms won't absorb much water.
After cleaning your mushrooms, you can spread them out to dry on a kitchen towel or paper towels. You can also use a salad spinner lined with paper towels to remove excess water. If you're working with portobellos, consider removing the gills on the underside of the cap first, as they tend to retain water.
While some people believe that mushrooms shouldn't be washed, there is evidence to suggest that this isn't true. Mushrooms can be washed just like any other produce, and doing so gives them a fresh start before they're cooked and consumed.

Foraged mushrooms should be soaked in a bowl of water and vinegar and rinsed before eating
While some people believe that mushrooms should not be washed before cooking, this is a myth. Mushrooms are mostly water, so a little more is not going to change their flavour or texture. In fact, mushrooms are often grown in manure or rotting wood, and store-bought mushrooms often arrive with some of the growing medium still clinging to their caps. Therefore, it is important to wash mushrooms before cooking and consuming.
Foraged mushrooms, in particular, may need to be soaked and rinsed before eating. Wild mushrooms can harbour bugs or have dirt and grit from the woodland floor. Foraged mushrooms such as chanterelles may be pristine or covered with the duff of the forest floor, depending on where they were collected. Therefore, it is important to check foraged mushrooms carefully for tiny bug holes at the stem end. If there are no bug holes, wash them following the method for wild hen of the woods. If there are bug holes, add a tablespoon of salt to 4 cups of water, swoosh to dissolve the salt, then soak the mushrooms for 20 minutes. Drain and repeat. Dry the mushrooms on a double layer of cotton dish towels. The salty water will evict any tiny creatures.
If you are concerned about food-borne illnesses, you can soak foraged mushrooms in clean water with a few drops of colloidal silver, which kills E. coli, salmonella, and giardia. You can also use a pressure cooker to sterilize mushrooms, as the high temperature will kill many bad bugs.
It is worth noting that mushrooms are delicate, and their high moisture content makes them extremely perishable. Therefore, it is best to wash mushrooms just before cooking and to dry them thoroughly after washing.
