How to Wash Polyester Pillows: A Complete Care Guide

Polyester pillows are a popular choice for their affordability, hypoallergenic properties, and easy maintenance.

But many of us have been there—wondering if tossing them into the washer is a good idea, or if it’ll leave you with a lumpy, unusable mess.

Fortunately, with a few key precautions, washing polyester pillows is not only possible but surprisingly simple.

In this guide, you’ll learn exactly how to get them clean, dry, and fluffy again, whether you use a washing machine or prefer hand-washing.

Can Polyester Pillows Be Washed?

Yes, most polyester pillows can be washed, but it’s important to follow specific care instructions to avoid damage.

What You Need to Know:

• Polyester is a durable synthetic material that holds up well to water.

• Aggressive wash cycles or hot water can break down fibers over time.

• Always read the care label before washing to ensure it’s machine washable.

Quick Tip:

If your pillow doesn’t have a label, stick to a gentle cycle with cold water to play it safe.

Clean, fluffy pillows go hand-in-hand with a quality mattress. The supportive layers of a Puffy Lux Mattress allow pillows to retain their structure while enhancing nightly comfort.

How to Wash Polyester Fiber Pillows

Polyester fiberfill pillows are among the easiest to wash if done right.

Their resilience and quick-drying nature make them ideal for busy households looking to keep bedding fresh without the hassle.

Follow these steps to keep them fresh and in good shape.

Washing Instructions:

1. Pre-Treat Stains:

   • Use a mild detergent or stain remover on any visible spots, such as makeup, sweat, or drool.

   • Let it sit for 10–15 minutes before washing to help lift stubborn marks.

   • For extra care, gently blot the area with a damp cloth before loading the pillow.

2. Machine Wash on Gentle Cycle:

   • Use cold or warm water, not hot, to protect the synthetic fibers.

   • Select a gentle or delicate cycle to avoid excessive agitation that can shift the filling.

   • Wash two pillows at a time to balance the load and prevent them from bunching or tangling.

3. Use Mild Detergent:

   • Choose a fragrance-free, dye-free detergent if you have sensitivities.

   • Avoid bleach or fabric softener, which can break down the fibers and reduce loft.

   • Add detergent before the pillows to prevent direct detergent contact with fabric.

4. Rinse and Spin Twice:

   • An extra rinse helps remove all detergent residue, which can otherwise lead to stiffness.

   • A second spin helps reduce excess water before drying, cutting down on dryer time and energy use.

   • Check that pillows are free from lingering soap bubbles before transferring to the dryer.

Can You Wash Polyester Pillows in the Washing Machine?

Yes, you can! In fact, machine washing is often the most convenient method for polyester pillows.

Guidelines for Machine Washing:

• Use a front-loading washer: These are more gentle than top-loaders with agitators.

• Wash two pillows at a time: Keeps the machine balanced and ensures a thorough clean.

• Add towels: Helps prevent clumping and cushions the pillows during the cycle.

• Always double rinse: Polyester can trap soap, so this step ensures a fresh finish.

How to Wash Polyester Pillows in Washing Machine: Step-by-Step

Following a step-by-step approach helps maintain pillow structure and avoid sogginess.

With the right settings and prep, your pillows will come out clean, fresh, and ready to use again without any lumps or lingering dampness.

Full Process:

1. Remove pillow covers or protectors if present.

   • Check for zippers or seams and unzip if the cover is removable.

   • Wash covers separately for a thorough clean.

2. Place 1–2 pillows in the washer along with two clean towels.

   • This helps balance the load and prevents the pillows from slamming around.

   • Use towels that won’t bleed color or shed lint.

3. Add a small amount of mild liquid detergent.

   • Choose a gentle, low-suds formula suitable for delicate fabrics.

   • Avoid bleach or strong scented detergents to preserve fiber quality.

4. Set washer to delicate cycle with cold or warm water.

   • Cold water is safest for preserving fibers; warm water works better for deep cleaning.

   • Make sure the spin speed is set to low or medium.

5. Once the cycle finishes, run an extra rinse and spin cycle.

   • This ensures all detergent is removed and reduces residual moisture.

   • Gently press on the pillows to check for water buildup before drying.

6. Press out excess water gently, then proceed to drying.

   • Avoid wringing, which can shift the fill or damage seams.

   • Lay the pillows flat on a clean towel while waiting to load them into the dryer.

Once clean and dry, polyester pillows feel brand new—especially when paired with a Puffy Cloud Mattress, whose breathable surface helps extend pillow freshness between washes.

Can You Hand Wash Polyester Pillows?

Yes, hand washing is a great alternative if your washer is too small or the care label suggests avoiding machines.

How to Do It:

1. Fill a tub or basin with lukewarm water and mild detergent.

2. Submerge the pillow, gently squeezing to saturate.

3. Let it soak for 15–20 minutes.

4. Rinse thoroughly until no soap remains.

5. Press out water—don’t twist or wring.

6. Lay flat to dry or transfer to dryer on low heat.

This method is especially helpful for spot-cleaning or maintaining decorative pillows.

How Often Should You Wash Polyester Pillows?

• Every 3–6 months: Standard for general use.

• More frequently: If used nightly, especially by allergy sufferers or during cold/flu season.

• Immediately: After spills, stains, or illness.

Pillow protectors and cases should be washed more often—every 1–2 weeks.

Tips for Keeping Polyester Pillows Fresh Between Washes

• Use pillow protectors to reduce exposure to sweat, oils, and allergens.

  • Choose zippered, washable covers made of breathable fabric for added defense.

  • Wash protectors weekly to keep the pillow core cleaner for longer.

• Fluff daily to maintain loft.

  • A few firm shakes help redistribute the filling and prevent flat spots.

  • You can also toss them in the dryer on a no-heat setting for a 5-minute refresh.

• Air out once a month in sunlight to reduce odor and bacteria.

  • Set pillows outside on a clean surface for a few hours in indirect light.

  • Sunlight naturally neutralizes odors and can help keep pillows feeling fresh.

• Store extras in breathable containers when not in use.

  • Use cotton or linen storage bags to prevent mustiness.

  • Avoid plastic bins unless they’re ventilated, and label pillows by use or season for easy access.
