We all know that pillows play a critical role in ensuring a good night’s sleep. But while we wash our sheets and pillowcases regularly, the pillows themselves often get neglected. Over time, you might have noticed your once-pristine white pillows developing unsightly yellow stains. It can be a bit unsettling, and it’s easy to assume that those yellow spots are there to stay. But here’s the good news: these yellow stains aren’t permanent, and there are effective ways to remove them and restore your pillows to their former glory.
In this guide, we’ll explore why pillows turn yellow, how to clean them properly (even in the washing machine), and some expert tips to keep your pillows fresh and clean for longer.
Why Do Pillows Turn Yellow?
Yellow stains on pillows are a common problem, and they can make your pillows look dirtier than they really are. The primary culprit behind these stains is sweat. While you sleep, your body naturally produces sweat, and even though it may not seem like much, over time, that sweat seeps into the pillowcase and pillow. As sweat accumulates, it leaves behind yellowish or brownish stains that can build up over time.
But sweat isn’t the only factor that causes discoloration on pillows. Here are some other common reasons for those stubborn yellow stains:
- Oily Hair: If you have particularly oily hair or frequently go to bed with damp or wet hair, the oils and moisture can transfer to your pillow, contributing to stains.
- Skincare Products and Makeup: Applying night creams, lotions, or going to bed without removing makeup can leave residues that eventually stain the pillow.
- Drooling: While not the most glamorous reason, drooling during sleep is another cause of pillow stains.
Even though these stains are often hidden under a pillowcase, they’re still a reminder of how easily pillows can absorb the natural oils, sweat, and grime from our bodies. Thankfully, there are ways to clean your pillows and make them look and feel fresh again.
In addition to sweat, your hair can be the culprit: specifically, if it’s particularly oily or if you often go to bed with wet or damp hair. Certain types of make-up and skin care products can also be the cause of these yellow spots. It can also be drool. Putting a waterproof pillow protector before your pillowcase can help prevent much of the discoloration.
How to Clean Yellow Stains from Pillows in the Washing Machine
The good news is that most pillows are machine washable, and you can effectively remove the yellow stains by following a few simple steps. However, it’s important to do this the right way to avoid damaging the pillows or causing clumping inside the pillow filling.
1. Check Your Washing Machine Size
Before you start, make sure your washing machine is large enough to handle your pillows. While most washers can accommodate standard pillows, larger queen- or king-sized pillows might need extra space to tumble properly. If your washer is too small, you can always head to a laundromat to use one of their oversized front-loading washers.
- Why it’s important: A large washer allows enough room for the pillows to move around, ensuring they’re thoroughly cleaned. If the pillows are packed too tightly, they’ll just get wet but won’t properly wash.
2. Use the Gentle Cycle
Set your washing machine to the gentle or delicate cycle. This is key to preventing the pillow filling from breaking apart or becoming lumpy during the wash.
- Tip: Over-agitation can damage the internal filling, particularly with down or memory foam pillows, so always opt for a gentle wash.
3. Choose the Right Water Temperature
Use cold or warm water for washing pillows. Avoid hot water, as high temperatures can break down the materials in the pillow, especially synthetic or down-filled pillows.
- Why it matters: Hot water can cause the filament or fabric to deteriorate, reducing the lifespan of your pillows. Cold or warm water is much gentler on the pillow fabric and filling.
4. Don’t Overdo the Detergent
Less is more when it comes to laundry detergent. Use only about ¼ of a cup of detergent to avoid buildup inside the pillow, which can be harder to rinse out.
- Skip the fabric softener: Fabric softener can create a residue on pillows, leading to a film that attracts more dirt and oils. It’s best to avoid it.
5. Rinse Thoroughly
Ensure that the washing machine rinses out all the detergent. If your washer has an extra rinse option, select it. This step helps to remove any lingering detergent residue, which can attract more oils and lead to stains later.
6. Dry the Pillows Properly
When drying pillows, it’s crucial to do it the right way to avoid mildew or clumping of the filling. Use the dryer’s low-heat setting and throw in a couple of clean tennis balls or dryer balls. These help break up any clumps of filling and keep the pillows fluffy.
- Take your time: Down-filled pillows may take longer to dry, so be patient. Ensure the pillows are completely dry before putting them back on the bed to prevent mold or mildew from forming.
- Dryer sheet optional: Feel free to toss in a dryer sheet to reduce static, but this step is optional and purely for personal preference.
Other Methods for Cleaning Pillows
If your pillow isn’t machine washable or you’d prefer to use a gentler approach, there are other ways to clean and freshen up your pillows.
Hand Washing Your Pillows
If you prefer to wash your pillows by hand, or if your pillows’ care labels advise against machine washing, here’s how you can clean them the old-fashioned way:
- Step 1: Choose a sunny day and take the pillows outside.
- Step 2: Beat them gently with a clean broom handle or rug paddle to remove dust and dirt.
- Step 3: Let them air out for a few hours in the sun, which can help naturally sanitize the pillows.
For foam pillows, avoid soaking them in water. Instead, use your vacuum’s upholstery attachment to remove dust and dirt from the surface.
Pillow Maintenance Tips: How to Keep Pillows Clean and Fresh
Even after you’ve cleaned your pillows, there are some easy ways to prevent stains from building up again and keep your pillows looking fresh for longer.
1. Use Pillow Protectors
One of the best ways to prevent yellow stains from forming in the first place is by using pillow protectors. These are thin, washable covers that go underneath your pillowcase. A waterproof pillow protector will provide an extra barrier to block sweat, oils, and other substances from reaching your pillow.
- Tip: Wash your pillow protectors weekly along with your sheets to ensure maximum cleanliness.
2. Fluff Your Pillows Daily
Give your pillows a quick fluff each day when you make the bed. Fluffing helps redistribute the filling and keeps your pillows plump and comfortable, while also allowing them to air out slightly.
3. Replace Your Pillows Regularly
No matter how well you care for them, pillows do have a limited lifespan. Over time, they lose their shape and become less supportive. If your pillows are flat, lumpy, or no longer comfortable, it’s time to replace them. Most experts recommend changing pillows every one to two years.
4. Have Spare Pillows on Hand
If you find a pillow that you love, consider buying a few extras. This ensures that when your current pillows wear out, you’ll have replacements ready. Plus, it’s always good to have spare pillows available for guests.
When It’s Time to Say Goodbye
Even with regular cleaning, pillows eventually wear out. If your pillow has become lumpy, flat, or is no longer providing the support you need, it’s time to retire it. Old pillows can also harbor allergens like dust mites, which can aggravate allergies. Treat yourself to a fresh pillow once a year (or as needed) to ensure you’re getting the most restful sleep possible.
Conclusion: Keep Your Pillows Spot-Free and Fresh
Yellow pillow stains may be unpleasant to look at, but they’re not as bad as they seem. With proper washing techniques and a little extra care, you can remove those stains and enjoy clean, fresh pillows for longer. Whether you choose to machine wash, hand wash, or simply fluff your pillows daily, these steps will help keep your pillows in great shape. And remember, adding pillow protectors and maintaining a regular cleaning routine will ensure your pillows stay fresh, comfortable, and stain-free.
Sleep soundly knowing your pillows are clean and ready for use!
