How to Clean Dirty Bed Pillows So They Turn White and Smell Fresh
Before You Start: Check the Label
Always read the care label on your pillow. Most polyester and down pillows are machine-washable. Memory foam or latex pillows should not be machine washed (instructions included below).
What You’ll Need
- Mild liquid laundry detergent
- Baking soda
- White vinegar
- Hot water (if fabric allows)
- Washing machine
- Dryer with clean tennis balls or dryer balls
Method 1: Washing Machine (For Polyester or Down Pillows)
Step 1: Pre-Treat Yellow Stains
Mix:
- ½ cup baking soda
- Enough warm water to make a paste
Apply to yellow or dark areas. Let sit for 30 minutes.
Step 2: Load the Washer Correctly
- Place two pillows in the washer to balance the load
- Use hot water if the label allows (this helps whiten)
- Add:
- Regular amount of detergent
- ½ cup baking soda directly into the drum
Step 3: Add Vinegar for Odor Removal
During the rinse cycle, add:
- ½ cup white vinegar
This removes detergent residue and neutralizes odors.
Step 4: Extra Rinse
Run an extra rinse cycle to ensure all soap is removed. This prevents stiffness and odors.
Drying the Pillows Properly
Step 5: Dry Completely
- Dry on low to medium heat
- Add 2–3 clean tennis balls or dryer balls to fluff pillows
- Pause drying occasionally to break up clumps
Pillows must be 100% dry to prevent mildew.
Method 2: Hand-Cleaning Memory Foam or Latex Pillows
Step 1: Spot Clean
- Mix warm water with a small amount of mild detergent
- Gently blot stained areas with a cloth
Step 2: Deodorize
- Sprinkle baking soda over the entire pillow
- Let sit for several hours or overnight
Step 3: Air Dry
- Shake off baking soda
- Air dry in a well-ventilated area away from direct sunlight
Never soak or wring memory foam.
How Often to Wash Pillows
- Every 3–4 months
- Immediately if heavily stained or odor develops
Use pillow protectors to keep them clean longer.
Extra Tips to Keep Pillows White and Fresh
- Always wash pillowcases weekly
- Shower before bed to reduce oils and sweat buildup
- Use pillow protectors under pillowcases
- Avoid fabric softener—it traps odors
Bottom Line
With the right method, pillows can be restored to clean, white, and fresh-smelling condition instead of being thrown away. Proper washing and thorough drying are the keys.
