How to Wash Pillows in the Washing Machine: The Complete Step-by-Step Guide
Knowing how to wash pillows in the washing machine is essential for maintaining a clean, healthy, and comfortable sleeping environment. Many people regularly wash their sheets and pillowcases but forget that pillows themselves collect sweat, body oils, dust mites, dead skin cells, allergens, and bacteria over time. Even if your pillow looks clean from the outside, the inside filling may contain contaminants that can affect sleep quality and trigger allergies.
Fortunately, most pillows can be safely cleaned in a washing machine when the correct method is used. Washing pillows properly not only removes dirt and odors but also restores their softness, fluffiness, and overall lifespan. However, using the wrong detergent, water temperature, or drying technique can damage the pillow filling and reduce its comfort.
This complete guide explains everything you need to know about how to wash pillows in the washing machine, including which pillows are machine washable, how often they should be cleaned, the best washing settings, drying techniques, and common mistakes to avoid. By following these steps, you can enjoy fresh, hygienic pillows that support a healthier night’s sleep.
Why Washing Your Pillows Is Important
Pillows absorb much more than most people realize. Every night they collect perspiration, natural body oils, hair products, saliva, dust, pollen, pet dander, and microscopic dust mites. Over time these contaminants build up deep inside the pillow where a pillowcase cannot protect against them.
Regular pillow washing improves sleep hygiene by removing allergens and bacteria that may contribute to skin irritation, unpleasant odors, asthma symptoms, and allergies. Clean pillows also maintain their loft better, providing proper neck and head support.
Experts generally recommend washing washable pillows every three to six months, depending on your sleeping habits, allergies, and whether pets sleep on the bed.
Can You Wash Pillows in the Washing Machine?
One of the most common questions homeowners ask is whether pillows can safely go into a washing machine. The answer depends on the pillow material.
Machine Washable Pillows
- Polyester pillows
- Cotton pillows
- Feather pillows
- Down pillows
- Fiberfill pillows
These pillows usually wash well when the care label instructions are followed carefully.
Pillows That Should Not Be Machine Washed
Certain pillow materials can become damaged during washing.
These include:
- Memory foam pillows
- Latex pillows
- Buckwheat pillows
- Gel foam pillows
Instead, these pillows should be spot-cleaned or hand-cleaned according to the manufacturer’s instructions.
Always check the care label before washing.
What You Need Before Washing Pillows
Preparing your pillows before washing helps prevent damage and improves cleaning performance.
Gather the following:
- Mild liquid laundry detergent
- Washing machine
- Dryer or drying rack
- Tennis balls or wool dryer balls
- Clean towels
- Stain remover (optional)
Avoid bleach unless the pillow manufacturer specifically recommends it.
Step 1: Check the Care Label
The care label provides important information regarding water temperature, washing method, drying temperature, and bleach usage.
Ignoring these instructions may permanently damage the pillow filling.
If the label says “Machine Wash,” you’re ready to proceed.
Step 2: Remove Pillow Protectors and Pillowcases
Take off all pillowcases and protective covers before washing.
Wash pillowcases separately with your regular laundry.
Inspect the pillow carefully for tears or loose stitching. Repair any damage before placing it into the washer to prevent the filling from escaping.
Step 3: Load Two Pillows at Once
One of the best washing machine tips is to wash two pillows together whenever possible.
This balances the washing machine drum, reduces vibration, and allows the pillows to move evenly during the wash cycle.
If you only have one pillow, add several towels to help balance the load.
Step 4: Choose the Right Washing Machine Settings
Selecting the correct settings is one of the most important parts of how to wash pillows in the washing machine.
Recommended settings include:
- Warm water
- Gentle cycle
- Extra rinse cycle
- Low spin speed
Warm water removes oils and dirt effectively without damaging most pillow fillings.
The extra rinse removes detergent residue that can leave pillows stiff.
Step 5: Use the Right Amount of Detergent
Many people mistakenly use too much detergent.
Only a small amount of mild liquid detergent is necessary because pillows absorb soap easily.
Excess detergent can remain trapped inside the filling and make pillows feel heavy or sticky.
Avoid powdered detergents because they may leave residue.
Step 6: Wash the Pillows
Place the pillows into the washing machine.
Add detergent.
Start the gentle wash cycle.
Allow the complete cycle to finish, including the extra rinse.
If your washing machine has a bulky bedding setting, this is often an excellent choice.
Step 7: Dry the Pillows Properly
Drying is just as important as washing.
Improper drying may cause mildew, mold, unpleasant odors, or clumping inside the pillow.
Place the pillows in the dryer using:
- Low heat
- Air fluff setting
- Wool dryer balls or clean tennis balls
The balls continuously fluff the pillows while breaking apart clumps.
Stop the dryer every 30 minutes and fluff the pillows by hand.
Continue drying until no moisture remains inside.
How to Keep Pillows Fluffy After Washing
Freshly washed pillows sometimes become flat if they are not dried correctly.
To restore fluffiness:
- Shake pillows several times.
- Massage the filling evenly.
- Use dryer balls.
- Avoid overheating.
- Allow pillows to cool completely before using them.
These steps help restore the pillow’s original shape.
How Often Should You Wash Pillows?
A good cleaning schedule keeps pillows hygienic and extends their lifespan.
General recommendations:
- Every 3–6 months for most households.
- Every 2–3 months for allergy sufferers.
- Immediately after illness.
- More often if pets sleep on the bed.
Replacing pillows every one to two years is also recommended if they no longer provide adequate support.
Common Mistakes to Avoid
Many pillows become damaged because of simple mistakes.
Avoid the following:
- Using too much detergent.
- Washing memory foam pillows in the machine.
- Skipping the extra rinse cycle.
- Drying on high heat.
- Storing pillows while damp.
- Washing damaged pillows without repairing them first.
Avoiding these mistakes helps your pillows remain soft and durable.
Extra Tips for Cleaner Pillows
Using pillow protectors significantly reduces dirt buildup and extends the time between washes. Airing pillows outside on a dry day helps remove odors and moisture naturally. Vacuuming pillows occasionally can reduce dust accumulation, especially for allergy sufferers. Rotating pillows regularly also promotes even wear and helps them maintain their shape over time. Combining these habits with regular machine washing keeps your pillows fresh, comfortable, and supportive for years.

Frequently Asked Questions (FAQs)
1. Can all pillows be washed in the washing machine?
No. Polyester, cotton, feather, down, and fiberfill pillows are usually machine washable, while memory foam, latex, buckwheat, and many gel pillows should not be machine washed unless the manufacturer specifically allows it.
2. How often should I wash my pillows?
Most pillows should be washed every three to six months. If you have allergies, sweat heavily, or share your bed with pets, washing them every two to three months is recommended.
3. What detergent is best for washing pillows?
A mild liquid laundry detergent is the best choice because it rinses out more easily than powdered detergent and is less likely to leave residue inside the pillow.
4. Can I use bleach to wash pillows?
Bleach is generally not recommended unless the care label specifically states that it is safe. Bleach can weaken fabrics and damage certain pillow fillings.
5. Why should I wash two pillows together?
Washing two pillows at the same time helps balance the washing machine drum, reducing vibration and allowing both pillows to clean more evenly.
6. How do I dry pillows without making them lumpy?
Dry pillows on low heat or an air-fluff setting with wool dryer balls or clean tennis balls. Pause the dryer occasionally to fluff the pillows by hand until they are completely dry.
7. How can I tell if my pillow is completely dry?
Squeeze the pillow and feel the center carefully. If there is any coolness or dampness inside, continue drying. Even slight moisture can lead to mildew or unpleasant odors.
8. How long do pillows usually last?
Most synthetic pillows last about one to two years, while high-quality down or feather pillows can last five years or more with proper care. Replace pillows when they lose their shape, become lumpy, or no longer provide adequate support.
9. Can I wash pillows with other laundry?
It is best to wash pillows separately or with another pillow of similar size. Mixing them with heavy items like jeans or towels can reduce cleaning effectiveness and place extra strain on the washing machine.
10. What is the best way to keep pillows clean between washes?
Use zippered pillow protectors, wash pillowcases weekly, air out your pillows regularly, and spot-clean stains as soon as they occur. These simple habits reduce dirt buildup and help extend the life of your pillows.
