Here’s how to clean dirty bed pillows to leave them white and smelling sweet.

by
Over time, bed pillows absorb body oils, sweat, hair products, and drool—leaving behind yellow stains, stale odors, and dust mites. Luckily, you can easily restore them so they look bright white and smell completely fresh.

Here is a step-by-step method to deep-clean, whiten, and freshen your pillows using basic household staples:

Step 1: Check the Care Tag

  • Machine-Washable: Standard fiberfill, down, and feather pillows can almost always be machine-washed.
  • Hand-Wash or Spot-Clean Only: Solid memory foam or latex pillows should never go into a washing machine or dryer, as agitation breaks down the material.

Step 2: The Brightening & Deodorizing Wash

For machine-washable pillows, wash two at a time to keep your washing machine balanced during the spin cycle.

The Whitening Mixture:

  • Regular laundry detergent
  • 1 cup hydrogen peroxide (or oxygen bleach) to lift yellow sweat stains naturally
  • 1 cup baking soda to neutralize deep-seated odors and soften water
  • ½ cup white vinegar (added during the rinse cycle) to dissolve detergent residue and eliminate bacteria

How to Wash:

  1. Fill your top-load machine (or set your front-loader) with warm or hot water.
  2. Add your laundry detergent, hydrogen peroxide, and baking soda directly to the water or drum so they dissolve before adding the pillows.
  3. Place two pillows in the washer vertically (standing up around the agitator if using a top-loader).
  4. Run a gentle or delicate cycle with an extra rinse and spin cycle to ensure all soap is completely flushed out.

Step 3: Drying and Fluffing (Crucial Step)

Getting pillows 100% dry is critical to prevent mold, mildew, and a sour smell from developing deep inside the fill.
  1. Add Dryer Balls: Toss the pillows into the dryer along with 2 to 3 wool dryer balls (or clean tennis balls tucked inside socks). As they tumble, the balls repeatedly hit the pillows, breaking up clumps and restoring their original fluff.
  2. Add Essential Oils: To leave them smelling sweet, add a few drops of lavender, eucalyptus, or tea tree essential oil onto your wool dryer balls before running the dryer.
  3. Dry on Low Heat: Run the dryer on a low-heat or air-fluff setting for at least 1 to 2 cycles. High heat can melt synthetic fibers or damage down.
  4. The Squeeze Test: Before taking them out, squeeze the thickest part of the pillow firmly. If you feel any cool dampness or heaviness, keep drying!

How to Clean Memory Foam / Solid Latex Pillows

  1. Remove and Wash the Cover: Unzip the outer casing and wash it in the laundry machine with warm water and baking soda.
  2. Deodorize the Core: Dust both sides of the foam pillow generously with baking soda. Let it sit for 1 to 2 hours to absorb trapped sweat and odors, then thoroughly vacuum it using a clean upholstery attachment.
  3. Spot-Clean Stains: Mix a few drops of mild dish soap and hydrogen peroxide in warm water. Dip a cloth in the mixture, wring it out so it’s only slightly damp, and gently dab any remaining yellow spots. Allow it to air-dry completely near a window or fan.

Daily & Weekly Maintenance Tips

  • Use Pillow Protectors: Zippered, waterproof pillow protectors keep sweat, moisture, and oils from penetrating into the core pillow in the first place.
  • Sunlight Power: Sunbathing your pillows outdoors on a bright, sunny afternoon for a couple of hours naturally bleaches light stains and kills odor-causing bacteria.
