Wash Pillows Without Ruining Them

Materials

• 2-3 tablespoons Mild liquid laundry detergent (Use less than normal to avoid residue buildup in the fill) — $0.50
• 3 balls Tennis balls or wool dryer balls (Clean tennis balls work fine if you don't have dedicated dryer balls) — $8-$15 (reusable)

Step by step

1. Prep · 5 min

   Know Your Pillow First

   Look for the sewn-in tag and read what it says. Most down and synthetic pillows say machine washable. Memory foam and latex almost never do—those need spot cleaning only. If the label is long gone, squeeze the pillow and feel what's inside. Loose, fluffy fill is usually washable. Dense foam that springs back slowly is not.

   Tip: If you're unsure about the fill, wash one pillow first as a test run before committing the whole set.

   Inspect for Damage

   Strip off everything—pillowcases, pillow protectors, zippered covers. Check the bare pillow for rips or weak seams. A small tear will become a big problem when agitated in water. If you find damage, hand-stitch it closed with doubled thread before washing, or you'll have loose fill everywhere.

   Tip: Wash pillow protectors separately with regular laundry—they don't need the special handling the pillow itself requires.
3. Washing · 45 min

   Balance the Load Correctly

   Put two pillows in the washer at once. This balances the load and prevents the machine from shaking itself across the floor during spin cycle. If you only have one pillow to wash, add a couple bath towels to even things out. Use a front-loader if possible—top-loaders with agitators can be rough on pillow seams.

   Tip: Submerge pillows fully before starting the cycle so they don't float and wash unevenly.
4. Washing · 45 min

   Go Light on Soap

   Add half the usual amount of liquid detergent—too much soap leaves residue that's hard to rinse out. Select gentle or delicate cycle with warm water. Run an extra rinse cycle to make sure all soap is gone. Leftover detergent makes pillows stiff and can irritate skin later.

   Tip: Skip fabric softener entirely—it coats fill material and reduces fluffiness over time.
5. Post-wash · 5 min

   Express Without Squeezing

   After the final spin, pillows will still be quite wet. Press them gently between your hands to push out extra water—don't wring or twist, which damages fill. The goal is to reduce drying time, not get them completely dry by hand. Synthetic pillows will feel heavy and dense at this stage.

   Tip: If water runs gray or brown when you squeeze, run another rinse cycle—the pillow wasn't clean yet.
6. Drying · 2-3 hours

   Low Heat Brings Back Loft

   Toss pillows in the dryer with three clean tennis balls or wool dryer balls. These break up clumps and restore loft as the pillow dries. Use low heat or air-dry setting. High heat can melt synthetic fills or damage down feathers. Check every thirty minutes, fluffing and rotating pillows by hand.

   Tip: Down pillows take longer to dry than synthetic—expect three to four hours, and make sure they're bone-dry before stopping.
7. Final check · 5 min

   Verify Complete Dryness

   Press the pillow to your cheek and feel for any coolness or dampness. Smell it—there should be no musty or damp odor. Squeeze the center hard and feel for any dense, heavy spots where moisture is trapped. If you detect any dampness at all, keep drying. Even slight moisture leads to mildew.

   Tip: When in doubt, run another thirty-minute cycle—over-drying is not a risk here, but under-drying ruins pillows permanently.
8. Finish · 5 min

   Restore Full Fluff

   Once fully dry, give each pillow a good karate chop down the middle and fluff from all sides to redistribute fill evenly. Put on a clean protector if you use one, then a fresh pillowcase. Your pillows should feel noticeably lighter and bouncier than before washing.

   Tip: Wash pillows twice a year at minimum—every three months if you sweat heavily at night or have allergies.

Field Notes

• Linda K. — I learned the hard way to check pockets before washing decorative throw pillows—one had a hidden zipper compartment with the tag and poly-fill sample inside. The sample exploded in the wash and turned into a snowstorm of tiny beads throughout the entire load. Now I unzip everything and double-check before any pillow goes in the machine. — March — Portland, OR
• Marcus T. — Texas humidity taught me that air-drying pillows outside doesn't work. They'd sit on the line for hours, feel dry on the surface, then grow mildew inside within two days. Machine drying on low is the only way to get the core completely dry. If your dryer has a moisture sensor setting, use it—it'll keep running until the pillow is actually done instead of guessing on time. — July — Austin, TX
• Rachel P. — Down pillows compress during washing and look ruined when they come out—don't panic. The drying process with tennis balls brings them back to life, but it takes patience. I set a timer and check every half hour, giving them a hard shake and flip. By hour three they're fully restored, but that first look out of the washer always makes me think I've destroyed them. — November — Denver, CO
