Whether mushrooms are pre-washed or not depends on the brand and type of mushroom. Wild mushrooms, such as chanterelles and oysters, are often harvested from forest floors and can be very dirty, whereas cultivated mushrooms are grown in sanitized, composted peat moss and are usually pretty clean. Opinions vary on whether mushrooms need to be washed before cooking, but most sources agree that they should be rinsed or soaked in water and then dried on paper towels.

What You'll Learn
Wild mushrooms may be dirty and require a good wash
Wild mushrooms, such as chanterelles and oysters, may be dirty and require a good wash. They are often harvested from forest floors and can come with dirt, leaves, needles, and bugs attached. These wild mushrooms are also usually more delicate than cultivated mushrooms, so they may fall apart when spun.
That being said, it is a myth that washing mushrooms is a bad idea. Mushrooms are mostly water, so a little extra water will not significantly change their flavor or texture. In fact, mushrooms lose moisture when exposed to heat, so any extra water will simply cook out.
However, it is important to note that mushrooms can absorb water, so they may become soggy if washed. This is especially true for wild mushrooms, which tend to absorb more water than cultivated mushrooms. Therefore, it is recommended to wash wild mushrooms as gently as possible.
- Cut the mushroom into pieces before washing.
- Submerge the pieces in lukewarm water and agitate them to remove any dirt or grit.
- Remove the mushrooms from the water and check that all dirt and grit have been removed.
- Pat the mushrooms dry with clean kitchen towels.
- If there are bug holes in the stems, add salt to the washing water (1 tablespoon per 4 cups of water).
- Wash wild mushrooms just before using them, as unwashed mushrooms have a longer shelf life.

Mushrooms are porous and will soak up water
If your mushrooms are visibly dirty, you can try using a damp paper towel or clean kitchen towel to gently wipe them. Alternatively, if they are especially dirty, you can rinse them under cold water, but be sure to shake off the excess water and dry them as much as possible with a paper towel or kitchen towel before cooking. If your mushrooms have lots of nooks and crannies that are hard to get to, you can fill a bowl with water, swish the mushrooms around to dislodge any debris, then quickly transfer them to a paper-towel-lined plate or baking sheet. Adding salt or vinegar to the water may help to remove any tiny bugs or critters living in the mushrooms.
If you are using pre-sliced mushrooms, avoid dunking them in water and spinning them dry, as they will inevitably fall apart. Instead, gently wipe them with a damp paper towel or kitchen towel. Similarly, wild mushrooms like chanterelles and oysters are often more delicate, so they will likely fall apart if spun. You can still rinse them, but be careful when drying them.
While it is generally recommended to avoid washing mushrooms before storing them, some sources suggest that you can wash mushrooms just before you are ready to cook them and then spread them out to dry on paper towels or a clean cotton dish towel.

Pre-sliced mushrooms shouldn't be washed
It is generally not recommended to wash pre-sliced mushrooms. This is because pre-sliced mushrooms are more delicate than whole mushrooms and are more likely to fall apart when washed. While rinsing whole mushrooms is possible, pre-sliced mushrooms will inevitably disintegrate if dunked in water and spun dry.
Mushrooms are porous and will absorb water, which can dilute their flavour and affect their texture, making them soggy, rubbery, or slimy. This is especially unpleasant if the mushrooms are intended for a salad, as waterlogged raw mushrooms have a particularly unappealing texture.
If your pre-sliced mushrooms appear dirty, it is recommended to gently wipe them with a damp paper towel or cloth to remove any debris. Alternatively, you can use a dry pastry brush or a dry paper towel to gently brush off any dirt. It is important to be gentle when cleaning pre-sliced mushrooms to avoid damaging them.
It is worth noting that cultivated mushrooms, such as cremini, portobello, or white button mushrooms, are often grown in sanitized, composted peat moss. Therefore, what may appear to be dirt in the package is actually safe to eat and not true dirt.
To avoid the hassle of cleaning pre-sliced mushrooms, it is generally recommended to purchase whole mushrooms instead. Whole mushrooms are fresher, last longer, and are not as challenging to slice as some believe. By choosing whole mushrooms, you can ensure that your mushrooms are clean and dry, ready for your desired preparation method.

Cultivated mushrooms are not that dirty
There is much debate in the culinary world about the best way to clean mushrooms. While some advocate for a water rinse, others suggest wiping them with a dry towel. However, it is important to note that cultivated mushrooms are not that dirty. They are grown in sanitized, composted peat moss, which is safe to eat. This peat mixture is integral to large-scale mushroom growing and provides moisture and support for the developing fungi. While it may look like dirt, it is not actually soil but rather remnants of the growing process.
That being said, it is still a good idea to give your mushrooms a quick rinse before cooking, especially if you plan to sauté, bake, or roast them. While mushrooms shouldn't be soaked in water, a quick rinse and gentle dry before use will ensure any remaining dirt is removed. If the mushrooms have a lot of nooks and crannies that are hard to reach, you can fill a bowl with water, toss the mushrooms in, and swish them around to dislodge any debris. Just be sure to use as little water as possible and cook them right away to avoid sogginess.
If the mushrooms are only slightly dirty, you can simply run them under the faucet individually, rubbing any dirty spots with your fingers. Then, transfer them to a paper towel to absorb any extra water. Alternatively, you can use a dry pastry brush or a dry paper towel to gently rub off any dusty or muddy bits. It is worth noting that any naturally occurring discoloration on the caps and stems of mushrooms may look like dirt but will never wash off.
In summary, while it is generally a good idea to give your cultivated mushrooms a quick rinse, you don't need to stress about removing every speck of dirt. This is because cultivated mushrooms are not that dirty, and much of what looks like dirt is actually safe-to-eat remnants of the growing process.

Different types of mushrooms need different cleaning methods
Mushrooms are not pre-washed, and it is important to clean them before cooking. There are two main schools of thought on how to clean mushrooms: the first suggests that mushrooms should never be washed under water, while the second argues that it is perfectly fine to do so.
Those who advise against washing mushrooms under water recommend using a damp paper towel to gently wipe away any dirt. This method is suitable for mushrooms that are not too dirty, such as common store-bought mushrooms like portobello, cremini, buttons, and shiitake, which often only have a small amount of growing medium clinging to their caps.
On the other hand, some people advocate for washing mushrooms under running water, especially if the mushrooms are very dirty or have lots of nooks and crannies that are hard to clean. This method is suitable for wild mushrooms like chanterelles and oysters, which can be quite delicate and may fall apart if spun, but can still be rinsed whole. For these mushrooms, it is recommended to use as little water as possible and to cook them right after washing to avoid sogginess.
Additionally, certain types of mushrooms may require specific cleaning methods. For example, morels, with their distinct honeycomb shape, can be particularly prone to dirt and debris getting stuck in their crevices. It is recommended to first shake them in a paper bag to loosen any dirt and then swish them around in a bowl of cold water with dissolved salt to dislodge any remaining dirt. Chanterelles, another type of wild mushroom, can be cleaned using either the paper towel or water rinse method, depending on their level of dirtiness.
