Can You Wash Pillows in the Washing Machine?
Yes, most pillows can be safely washed in a washing machine, provided you check their care labels first. Machine washing offers an efficient way to remove allergens, dust mites, sweat, and oils, restoring freshness and loft to your bedding. However, not all pillow types are suitable for machine washing; delicate materials like down or feathers may require special care or professional cleaning, while memory foam and latex pillows are generally not washable.
- Check the pillow's care label before washing.
- Most synthetic and feather/down pillows are machine washable.
- Memory foam and latex pillows are typically not machine washable.
- Wash two pillows at a time for balance.
- Use a gentle cycle with mild detergent.
Before you begin the process of machine washing pillows, it's crucial to confirm the manufacturer's recommendations. A small tag sewn into the pillowcase or seam often provides specific instructions. Ignoring these can lead to damaged filling, torn fabric, or a pillow that loses its shape. If a label is missing or unreadable, a general rule is that synthetic-filled pillows (polyester, microfiber) and many feather or down-filled ones can handle a washing machine cycle. These are designed to withstand agitation and water, unlike solid foam cores.
Identifying Washable Pillow Types
The first step is always to identify what kind of pillow you have. Synthetic-filled pillows are generally the most resilient. These are often labeled as polyester, microfiber, or cluster fiber. They tend to be durable and can tolerate regular washing without significant degradation. Feather and down pillows, while natural, are also frequently designed to be machine washable. The key here is often the quality of the down and the construction of the pillow's casing. A well-made down pillow can be cleaned at home, but it's essential to use the right settings and detergent to avoid clumping or damage to the natural filling.
On the other hand, pillows made from memory foam, latex, or solid foam cores are typically spot-clean only. The foam structure can absorb excessive water, become heavy and unbalanced in the machine, and may not dry thoroughly, leading to mold or mildew. If your pillow is made of these materials, refrain from putting it in the washing machine altogether. For these, a gentle spot clean with a damp cloth and mild soap is the recommended approach.
Preparing Your Pillows for the Washer
Proper preparation is key to successfully washing pillows in a washing machine. This involves ensuring they are ready for the wash cycle, which can involve removing covers and checking for any damage. If your pillows have removable outer covers, always take them off and wash them separately according to their specific care instructions. This allows the inner pillow to be cleaned more effectively and prevents excessive wear on the cover itself.
Pre-Wash Checks and Treatments
Before loading pillows into the washing machine, perform a thorough inspection. Look for any rips, tears, or loose seams. Small holes can become larger during the agitation of the wash cycle, potentially releasing filling and damaging your machine. If you find any damage, attempt to mend it with a strong needle and thread. For visible stains, a pre-treatment can make a significant difference. Apply a small amount of mild laundry detergent or a stain remover directly to the stained area, gently rub it in, and let it sit for about 10-15 minutes before washing. This is particularly helpful for yellowing caused by sweat or body oils.
It's also important to ensure you're washing pillows in pairs. This helps to balance the load in the washing machine. An unbalanced load can cause the machine to vibrate excessively, potentially damaging both the machine and the pillows. If you only need to wash one pillow, consider adding a couple of towels of similar weight and color to the drum to achieve a more even distribution of weight. This simple step helps maintain the smooth operation of your appliance.
Pre-treat stubborn stains on pillow covers or cases before machine washing by applying a paste of baking soda and water, letting it sit for 30 minutes, then gently scrubbing before laundering.
Washing Machine Settings for Pillows
Selecting the right washing machine settings is crucial for effectively cleaning pillows without causing damage. The goal is to use enough water and agitation to clean thoroughly but gently enough to preserve the pillow's structure and filling. For most washable pillows, a warm water temperature and a delicate or gentle cycle are recommended. Hot water can sometimes cause some fillings to clump or damage delicate fabrics, while cold water may not be effective enough in removing oils and allergens.
Choosing the Right Cycle and Temperature
When washing pillows in the washing machine, opt for a gentle or delicate cycle. These cycles use slower spin speeds and less aggressive agitation, which is ideal for maintaining the integrity of the pillow's filling, whether it's synthetic fibers, down, or feathers. Avoid heavy-duty or regular cycles, as their more vigorous action can lead to clumping of the filling or tearing of the pillow's fabric. The wash time should also be considered; a cycle that is too long can oversaturate the pillows and make drying more difficult.
Regarding water temperature, warm water is generally the most effective for cleaning. It helps to break down body oils, sweat, and common allergens that accumulate over time. However, always refer to the care label. If the label specifies cold water, adhere to that to prevent any potential damage. For down or feather pillows, some manufacturers recommend using a specific detergent designed for natural fibers, or a very mild, low-sudsing liquid detergent. Avoid using bleach or fabric softeners, as these can degrade the filling and the fabric over time.
Detergent Amount and Balancing the Load
Use only a small amount of mild liquid detergent. Too much detergent can be difficult to rinse out completely, leaving residue that can irritate the skin or cause the filling to clump. A quarter to half the normal amount, depending on the size of your load and machine, is usually sufficient. For those wondering about soil level on a washer, a higher soil level setting might seem appealing for a deep clean, but it often equates to more aggressive agitation, which should be avoided with pillows. Stick to the standard setting for the chosen gentle cycle.
As mentioned, washing two pillows at a time is essential for balance. This ensures the weight is distributed evenly around the drum, preventing the machine from becoming unbalanced and potentially damaging itself. If you have a top-loading machine, ensure the pillows are placed opposite each other. If you have a front-loading machine, place them side-by-side. This balance also helps the pillows move more freely through the water and detergent, leading to a more consistent clean.
Drying Your Pillows After Washing
Proper drying is just as critical as washing when it comes to cleaning pillows in a washing machine. Inadequate drying can lead to the growth of mold and mildew within the pillow's filling, which can be harmful and cause unpleasant odors. The most effective drying method for most washable pillows is using a machine dryer on a low heat setting, but air drying is also an option.
Machine Drying Techniques
The best way to dry pillows after they've been washed in the washing machine is to place them in a dryer on a low heat or air-fluff setting. High heat can damage or melt synthetic fillings and potentially scorch natural fibers like down. To ensure even drying and to help break up any clumps of filling that may have formed during washing, add a couple of clean dryer balls or tennis balls to the dryer. These will bounce around, fluffing the pillows and preventing the filling from settling into dense patches.
It's important to run the dryer for multiple cycles if necessary. Pillows can take a long time to dry completely, especially if they are dense or if the washing machine's spin cycle didn't extract as much water as possible. Check the pillows periodically during the drying process. Feel deep inside the pillow to ensure there is no residual dampness. If you detect any moisture, continue drying. Rushing this step can result in a pillow that feels dry on the outside but is still damp within, leading to mold and odor issues.
Revive flattened pillows by placing them in the dryer on a no-heat air-fluff cycle with dryer balls for 15-20 minutes after they are fully dry from washing.
Air Drying Considerations
If you prefer to air dry your pillows or if your dryer is unavailable, this method requires patience and the right conditions. Lay the pillows flat on a clean, dry surface, such as a drying rack or a well-ventilated area away from direct sunlight, which can degrade certain fabrics and fillings. Ensure good air circulation around the pillows. You may need to periodically fluff them by hand and rotate them to ensure even drying. This process can take 24-48 hours or even longer, depending on humidity and airflow, so it's vital to be thorough to prevent moisture retention.
For both machine and air drying, the ultimate goal is complete dryness. If you have any doubt, it's better to dry them for longer. A slightly over-dried pillow is preferable to one that harbors moisture. Once completely dry, give the pillows a good fluff by hand to restore their loft and shape before returning them to your bedding.
When to Avoid Machine Washing Pillows
While machine washing pillows is a common and effective cleaning method for many types, there are specific situations and materials where it's best to avoid the washing machine altogether. Understanding these exceptions helps protect your bedding investment and ensures you don't damage delicate materials or your appliance.
Materials That Shouldn't Go in the Washer
The primary reason to avoid machine washing a pillow is its material composition. As noted, memory foam, solid foam, and latex pillows are not designed to be submerged in water. The foam structure can absorb water like a sponge, becoming incredibly heavy and difficult to rinse and dry. This excessive moisture can lead to the breakdown of the foam, permanent deformation, and the growth of mold and bacteria, making the pillow unhygienic and unusable. These types of pillows are best cleaned by spot treatment with a damp cloth and mild soap, followed by thorough air drying.
Certain specialty pillows also pose risks. For example, pillows filled with buckwheat hulls or other natural grains should never be machine washed, as the filling will likely be ruined and can clog your machine. Likewise, electric or heated pillows contain electrical components that are incompatible with water and should only be cleaned according to their specific manufacturer's instructions, usually involving spot cleaning and airing out.
Signs Your Pillow Needs Professional Care or Replacement
Even if a pillow is technically machine washable, there might be reasons to reconsider. If a pillow is old, heavily stained, or has a filling that has significantly clumped or lost its loft, washing it might not yield satisfactory results. In such cases, it might be more practical and hygienic to replace the pillow. Look for signs like persistent odors that washing doesn't eliminate, significant lumps or unevenness in the filling even after drying, or fabric that is worn thin and showing signs of disintegration.
For very delicate or expensive pillows, such as high-loft down or silk-filled options, professional cleaning might be a safer bet. A professional cleaner has the expertise and specialized equipment to handle these materials gently, ensuring they are cleaned without damage. If you're unsure about a pillow's washability, it's always safer to err on the side of caution, consult the manufacturer's guidelines, or seek professional advice rather than risking damage in your home washing machine.
Alternatives to Washing Machine Pillow Cleaning
When machine washing isn't an option, or for quick refreshers between deep cleans, several effective alternatives exist for cleaning your pillows. These methods cater to materials unsuitable for washing machines or offer simpler ways to maintain pillow hygiene.
Spot Cleaning for Targeted Stains
Spot cleaning is the go-to method for pillows made of memory foam, latex, or those with delicate fillings that cannot tolerate full submersion. To spot clean, mix a small amount of mild detergent or a gentle upholstery cleaner with water. Dampen a clean cloth with the solution (do not saturate it) and gently blot the stained area. Follow up with a separate cloth dampened with clean water to rinse away the detergent residue. Allow the pillow to air dry completely, preferably in a well-ventilated area, away from direct heat or sunlight, which can degrade foam. Ensure the spot is fully dry before placing it back on your bed.
Deodorize pillows by sprinkling a generous amount of baking soda over them, letting it sit for at least 30 minutes (or longer for tougher odors), then vacuuming it off thoroughly.
Using Baking Soda for Deodorizing and Freshening
Baking soda is a fantastic natural deodorizer and can help freshen up pillows without water. For a light refresh, simply sprinkle a generous layer of baking soda over the entire surface of the pillow. Let it sit for at least 30 minutes, or even a few hours for more potent odors. The baking soda will absorb moisture and neutralize smells. Afterward, take the pillow outside and shake it vigorously to remove the baking soda, or use a vacuum cleaner with an upholstery attachment for a more thorough removal. This method is safe for almost all pillow types, including those unsuitable for machine washing.
Sunlight and Air Exposure
Pillows can benefit greatly from regular airing. On a sunny, breezy day, take your pillows outside and lay them flat in a spot where they can get direct sunlight and good airflow. Sunlight has natural sanitizing properties that can help kill bacteria and dust mites, while fresh air helps to dissipate odors and any lingering moisture. This is an excellent way to refresh pillows between washes, especially for those that cannot be washed frequently. Ensure they are thoroughly aired out, and if the sun is too intense, consider placing them in a shaded but well-ventilated area to prevent fading or material damage.
For those wondering how to wash tennis shoes in the washing machine, or if you can wash sneakers in the washing machine, the principles of using a gentle cycle and mild detergent often apply, but always check the shoe's material and manufacturer's advice. Similarly, if you're considering if you can wash a backpack in the washer, it depends heavily on its size, material, and any internal structures or electronics.
Frequently Asked Questions About Pillow Washing
Addressing common concerns can clarify the process of washing pillows and help ensure you achieve the best results. Many people wonder about the frequency of washing, specific issues like yellowing, and the general impact of machine washing on pillow longevity.
How Often Should I Wash My Pillows?
Generally, it's recommended to wash your pillows every 3 to 6 months. This frequency helps remove accumulated allergens, sweat, dead skin cells, and dust mites that can affect sleep quality and hygiene. However, this can vary based on personal needs; for instance, individuals with allergies or asthma may benefit from washing them more frequently, perhaps every 2-3 months. Pillow protectors can extend the time between washes by shielding the pillow from direct contact with sweat and oils.
Why Are My Pillows Yellowing?
Yellowing on pillows is typically caused by a combination of body oils, sweat, saliva, and lotions that seep into the pillow over time. While regular washing can mitigate this, some discoloration might set in. For washable pillows, pre-treating stains with a mild detergent or a baking soda paste before washing can help. If the yellowing is severe and the pillow is old, it might indicate that the filling has degraded, and it may be time for a replacement rather than trying to clean it.
Can Machine Washing Damage My Pillows?
Machine washing can potentially damage pillows if the wrong cycle, temperature, or detergent is used, or if the pillow's material is not suitable for washing. Overly aggressive cycles can cause filling to clump or shift, while high heat can melt synthetic fibers or damage delicate natural fillings. Always follow care labels and use gentle settings. For materials like memory foam, machine washing will almost certainly cause irreversible damage. If in doubt, opt for spot cleaning or professional laundering.
How Do I Know If My Pillow is Dry?
Ensuring a pillow is completely dry is vital to prevent mold and mildew. After washing machine pillows, check for dryness by squeezing the pillow firmly in the center. If you feel any dampness or hear a squishing sound, it's not fully dry. You can also feel the filling by hand, reaching deep into the pillow. If any part feels cool or damp, it needs more drying time. Air drying can take 24-48 hours, so be patient. Machine drying on low heat with dryer balls is generally faster and more effective for thoroughness.
What About Washing Machine Lint Traps?
While washing machine lint traps are crucial for collecting lint from clothes, they are less of a concern for pillows unless the pillow's fabric is shedding excessively or has loose threads that could snag. Most pillow casings are designed to hold their filling. However, it's good practice to check and clean your washing machine's lint trap regularly, regardless of what you're washing, to ensure optimal machine performance and prevent potential issues with drainage or water flow.
