Pillows go through more than most of us realize. Night after night they soak up sweat, oil, drool, and dead skin cells. Over time, this buildup attracts dust mites and bacteria. As a result, learning how to wash pillows properly keeps them fresher and extends their life. In fact, it can even help with allergies and skin breakouts. Most people only wash their pillowcases. However, they forget the pillow itself needs just as much attention.
Why Learning How to Wash Pillows Matters
A pillow that hasn’t been washed in months can double in weight. This is because sweat, skin cells, and dust mite debris build up over time. According to the Sleep Foundation, you should wash pillows every four to six months and pillowcases weekly. So, if you’ve been wondering how to wash pillows without ruining them, here’s the good news: you can clean most pillows safely at home. This includes down, synthetic, and memory foam pillows, as long as you follow the right method for the material.
How to Wash Pillows by Material Type
Not every pillow is made the same way. Therefore, how to wash pillows really depends on what’s inside them.
For example, synthetic (polyester) pillows are the easiest to wash. They can usually go straight into a washing machine.
On the other hand, down and feather pillows need a gentler cycle and extra rinsing. This is because leftover detergent can clump the feathers.
Meanwhile, memory foam pillows should never go in a washing machine. Since the foam absorbs water and can break down, you should spot clean these instead.
Finally, buckwheat or specialty pillows usually only need the cover washed. Meanwhile, you can wipe down or air out the inner filling separately.
Overall, checking the care label before you start is the simplest way to avoid a mistake, since it tells you exactly how to wash pillows made from that specific material.
Step-by-Step: How to Wash Pillows in a Washing Machine
For synthetic and most down pillows, a front-loading washing machine works best, since it’s gentler than a top-loader with an agitator. Here’s a simple process for how to wash pillows this way:
- First, check the care label for any specific warnings.
- Then, place two pillows in the machine at once to keep the load balanced.
- Next, use a mild liquid detergent, about half the amount you’d normally use.
- After that, wash on a gentle or delicate cycle with warm water.
- Finally, run an extra rinse cycle to remove detergent residue, especially for down pillows.
Additionally, the CDC’s guidance on dust mite control notes that hot water above 130°F kills dust mites effectively. So, use warm to hot water where the fabric allows for extra cleanliness.
How to Wash Pillows That Can’t Go in the Washer
Meanwhile, memory foam and some specialty pillows need a different approach entirely. In this case, the focus shifts from machine washing to spot cleaning and deodorizing:
- First, mix a small amount of mild detergent with cold water.
- Then, dab the solution onto stained areas with a clean cloth, working in small circles.
- Next, rinse the cloth and go over the area again with plain water to lift out the soap.
- After that, sprinkle baking soda over the entire pillow and let it sit for a few hours to absorb odors, then vacuum it off.
- Finally, let the pillow air dry completely in a well-ventilated spot, since trapped moisture inside foam can lead to mold.
Although this method of how to wash pillows that can’t be machine washed takes a bit more patience, it keeps the foam structure intact.
Drying Pillows the Right Way
Drying is actually where a lot of people go wrong. For instance, a pillow that isn’t dried thoroughly can develop mold or mildew inside, which is both unhealthy and hard to reverse. For machine-washed pillows, tumble dry on low heat and add a couple of clean tennis balls or dryer balls to the load. As a result, these help fluff the filling back up and break apart clumps that formed during washing. Since it can take two or three cycles to get a pillow completely dry, check it periodically by squeezing the center. If a pillow still feels damp or lumpy inside, keep drying rather than storing it, because residual moisture is the main cause of musty-smelling pillows.
How Often Should You Wash Pillows
Most experts, including those at the Mayo Clinic, recommend washing bedding regularly to reduce exposure to dust mite allergens, a common trigger for allergy and asthma symptoms. So, as a general guideline for how to wash pillows on a schedule:
- Pillowcases: once a week
- Pillow protectors: once a month
- Pillows themselves: every four to six months
- Replace pillows entirely: every one to two years, since fibers break down over time no matter how well you clean them
Overall, if you deal with allergies, sweat heavily at night, or have pets on the bed, it’s worth washing your pillows a little more often.
Final Thoughts
In the end, figuring out how to wash pillows the right way isn’t complicated. You just need to know what your pillow is made of and follow the correct cycle, detergent amount, and drying process. After all, a clean pillow isn’t just about comfort — it also means fewer allergens, less odor, and a longer-lasting pillow overall. So, building this into your regular laundry routine every few months is one of those small habits that makes a noticeably bigger difference than people expect.
