Pillows absorb sweat, body oils, dust mites, and allergens over time. Even if your pillow does not have a removable cover, you can still clean it safely and effectively at home. Knowing how to wash pillows properly helps extend their lifespan, improve hygiene, and create a healthier sleeping environment.
In this guide, you’ll learn the best methods for washing pillows without removable covers, including machine washing, hand washing, drying techniques, and care tips for different pillow materials.
Why You Should Wash Pillows Regularly
Many people wash pillowcases often but forget about the pillows themselves. Over time, pillows can collect:
- Sweat and skin oils
- Dust mites and allergens
- Dead skin cells
- Mold and mildew
- Odors and stains
Cleaning pillows every 3–6 months helps maintain freshness and supports better sleep quality.
Can You Wash Pillows Without a Removable Cover?
Yes, most pillows without removable covers can still be washed. However, the cleaning method depends on the pillow filling material.
Before washing, always check the care label attached to the pillow. Some pillows are machine washable, while others require hand washing or spot cleaning only.
Types of Pillows and Their Cleaning Methods
1. Polyester Fiberfill Pillows
These are the easiest pillows to clean and are usually machine washable.
Best Cleaning Method
- Machine wash with mild detergent
- Warm or cold water
- Gentle cycle
2. Down and Feather Pillows
Feather pillows can usually be machine washed but need careful drying to prevent clumping.
Best Cleaning Method

How to Wash Pillows in a Washing Machine
If your pillow is machine washable, follow these steps carefully.
Step 1: Remove Pillowcases and Protectors
Take off any pillowcases, covers, or protectors before washing.
Step 2: Inspect the Pillow
Check for:
- Tears or holes
- Loose seams
- Weak fabric
Repair any damage before washing to prevent filling from leaking out.
Step 3: Use Mild Detergent
Choose a gentle liquid detergent. Avoid:

Too much detergent can remain trapped inside the pillow.
Step 4: Wash Two Pillows Together
Place two pillows in the washing machine to balance the load.
Recommended Settings
- Gentle cycle

- Extra rinse cycle
The extra rinse helps remove detergent buildup.
Step 5: Dry Thoroughly
Proper drying is essential to prevent mold and mildew.
Dryer Tips
- Use low heat
- Add dryer balls or clean tennis balls
- Pause occasionally to fluff pillows
Drying may take several cycles.
How to Hand Wash Pillows Without Removable Covers
Hand washing is safer for delicate pillows like memory foam.
Step 1: Fill a Tub with Lukewarm Water
Use a bathtub, sink, or large basin.
Add a small amount of mild detergent.
Step 2: Gently Clean the Pillow
Press the pillow into the water gently. Avoid twisting or wringing.
Focus on stained or dirty areas.
Step 3: Rinse Thoroughly
Drain the soapy water and refill with clean water until all detergent is removed.
Step 4: Remove Excess Water
Press the pillow between towels to absorb moisture.
Do not twist the pillow.
Step 5: Air Dry Completely
Place the pillow in a well-ventilated area.
You can:
- Lay it flat on a clean towel
- Use a fan
- Dry outdoors in indirect sunlight
Make sure the pillow is fully dry before using it again.
How to Remove Yellow Stains from Pillows
Yellow stains are usually caused by sweat and body oils.
Homemade Cleaning Solution
Mix:
- 1 cup hydrogen peroxide
- ½ cup baking soda
- Mild detergent
Apply to stains before washing.
Let sit for 30 minutes, then wash normally.
How to Eliminate Odors from Pillows
If pillows smell musty or stale:
Baking Soda Method

- Let sit for several hours
- Vacuum thoroughly
This helps absorb odors naturally.
Common Mistakes to Avoid
Using High Heat
High dryer heat can damage filling materials and shrink fabrics.
Overloading the Washer
Pillows need enough space to clean properly.
Not Drying Completely
Damp pillows can develop mold and mildew quickly.
Washing Memory Foam in a Machine
This can permanently damage the foam structure.
How Often Should You Wash Pillows?

Replace Pillows Every

- 5 years for high-quality latex pillows
Tips to Keep Pillows Clean Longer
Use Pillow Protectors
Waterproof or allergen-proof protectors help reduce dirt buildup.
Air Out Pillows Monthly
Fresh air and sunlight help reduce moisture and odors.
Fluff Pillows Regularly
This helps maintain shape and prevents clumping.
Final Thoughts
