How to Wash Pillows in a Washing Machine Without Ruining Them

Washing your pillows at home can save you money, extend their lifespan, and keep your sleeping environment fresh and healthy. Many people wonder if pillows can be safely cleaned in a washing machine. The good news: most pillows—including those filled with down, feather, or synthetic fibers—can be machine-washed. However, there are some important steps and tips to ensure your pillows come out fluffy, clean, and undamaged.

Below, you’ll find everything you need to know about safely washing your pillows in a washing machine, practical advice for optimal results, and answers to the most common pillow-washing questions.


Understanding Your Pillow Type

Before you toss your pillows in the wash, it’s essential to check what they’re made of. This determines both how you’ll wash them and how often.

Common Types:

  • Synthetic (Polyester) Pillows: The most common type, known for durability.
  • Feather/Down Pillows: Lightweight and fluffy, but delicate.
  • Memory Foam Pillows: Not suitable for machine washing—spot clean these instead.
  • Latex Pillows: Also best spot cleaned due to potential damage in the washer.
  • Buckwheat Pillows: Do not wet-wash; empty and wash the cover only.

Always read the care label on your pillow for any specific instructions.


Step-by-Step Guide to Washing Pillows in a Machine

1. Preparation

Before washing, do the following:

  • Check the care label: Make sure the pillow can be machine-washed.
  • Repair any tears: Sew up any weak seams to prevent filling leakage.
  • Remove pillowcases/covers: Wash them separately for best results.

2. Loading the Washer

For optimal washing:

  • Wash two pillows at a time: This helps balance the washer and ensures an even clean.
  • Front-loading washers are ideal: Top-loaders with agitators can be harsh. If you have a top-loader, position pillows vertically to reduce stress on seams.

3. Choosing Detergent and Settings

  • Use a mild liquid detergent: Powder can leave residue. Only a small amount is necessary.
  • Select warm water: Hot water might damage some pillows, especially foam or down types.
  • Use a gentle/delicate cycle: This helps protect filling and fabric.

4. Extra Rinse and Spin

To ensure all detergent is washed out:

  • Add an extra rinse cycle: Residual soap can irritate skin or flare up allergies.
  • Select an extra spin cycle: Helps remove as much moisture as possible for easier drying.

5. Drying Pillows Properly

Drying is just as crucial as washing. Damp pillows are prone to mold and must be fully dry before use.

  • Tumble dry on low heat: Use the lowest setting to protect the pillow’s filling.
  • Add dryer balls or clean tennis balls: Toss two into the dryer with the pillows. They’ll help keep pillows fluffy by breaking up clumps.
  • Pause and fluff: Stop the dryer occasionally to check for clumping and ensure even drying. Fluff by hand if needed.
  • Dry thoroughly: It may take a few cycles to get the pillow completely dry, especially down or feather types.

Special Tips & Best Practices

  • Wash every 4-6 months: Keeping your pillows clean reduces dust mites and allergens.
  • Use pillow protectors: They reduce the need for frequent washing and extend the life of your pillows.
  • Spot clean stains promptly: Don’t let spills set. Dab stain with a mild soap and water mix before machine washing.
  • Avoid bleach: It can break down the pillow’s material.
  • Sunshine freshening: On a sunny day, lay washed pillows in the sun to dry for a boost of freshness and natural bacteria-killing power.

Common Challenges (And How To Avoid Them)

Clumping

  • Solution: Break up clumps manually during drying. Using dryer balls helps minimize this.

Loss of Shape

  • Solution: Fluff pillows regularly during dryers and don’t overstuff the machine.

Residual Odor

  • Solution: Use an extra rinse cycle and ensure pillows dry thoroughly. Leaving them damp can cause mildew smells.

Wet Spots After Drying

  • Solution: Restart the drying cycle until pillows feel bone-dry. Wet spots inside promote mold.

Benefits of Washing Pillows in the Washing Machine

  • Allergen Reduction: Machine washing removes dust mites, fungi, and other allergens.
  • Better Sleep Quality: Clean pillows smell fresher and feel softer.
  • Longer Pillow Life: Caring for your pillows keeps them supportive and prevents premature wear.
  • Money Saving: Regular washing can delay the need for new pillows.

Quick Reference: Washing Different Pillow Types

Pillow Type Machine Wash? Special Notes
Polyester Yes Standard wash instructions apply
Down/Feather Yes Use gentle cycle, extra rinse, low heat to dry
Memory Foam No Spot clean only—machine washing ruins the foam
Latex No Spot clean only—as with memory foam
Buckwheat No Empty hulls first, wash cover only

Practical Pillow Care Reminders

  • Avoid washing too often: Over-washing can shorten pillow lifespan, especially for delicate fills.
  • Replace pillows every 1-2 years: Even with care, pillows lose support over time.
  • Test pillow readiness: Fold the pillow in half; if it doesn’t spring back, it’s time for a new one.

Conclusion

Washing your pillows in a washing machine is simple and effective when done correctly. Pay attention to your pillow’s material, use a gentle cycle with a mild detergent, and always dry them thoroughly. With just a bit of extra care every few months, your pillows will stay fresh, clean, and cloud-soft for many nights to come.


Frequently Asked Questions (FAQs)

How often should I wash my pillows?

Aim to wash your pillows every 4–6 months. If you suffer from allergies, consider washing them more frequently.


Can I wash memory foam pillows in the washing machine?

No. Memory foam pillows should be spot cleaned only, as a full wash can damage their structure. To clean, use a slightly damp cloth and mild detergent, then air dry completely.


How can I make sure my pillows dry completely?

Use low heat in the dryer and add dryer balls or clean tennis balls to prevent clumping. Check and fluff the pillows every 30 minutes until they are thoroughly dry—both inside and outside.


Is it safe to use bleach or fabric softener when washing pillows?

It’s best to avoid bleach and fabric softener. Bleach can break down fillers and fabric; softeners can coat fibers and reduce fluffiness.


Why do my pillows smell after washing?

Odor usually means your pillows didn’t dry fully. Always use enough drying time and, if possible, dry pillows in the sun for extra freshness. If the smell persists, consider an extra rinse and re-drying.


Caring for your pillows keeps them cozy, clean, and long-lasting. With these tips and answers, you’re ready to give your pillows the gentle, effective cleaning they deserve!
