The headline “How to wash yellowed pillows: 3 tips to keep them white and new” is a common cleaning tip. Yellowing pillows are usually caused by sweat, body oils, saliva, skincare products, and moisture buildup over time. Washing can improve their appearance, but very old or heavily stained pillows may not return to a brand-new white colour.
3 tips to clean yellowed pillows
1. Check the care label first
- Most synthetic and many down/feather pillows can be washed, but always follow the manufacturer’s instructions.
- Replace pillows that are lumpy, damaged, mouldy, or no longer supportive.
2. Wash with the right method
For washable pillows:
- Use a mild detergent.
- Wash two pillows together if possible to keep the machine balanced.
- Use an extra rinse cycle to remove detergent residue.
- Dry completely—moisture left inside can encourage mould and odours.
3. Use whitening methods carefully
For white, washable fabrics, some people use:
- Oxygen-based bleach (often safer for fabrics than chlorine bleach).
- A pre-soak with an appropriate laundry product.
Be cautious with:
- Chlorine bleach: It can weaken some fibres and may actually worsen yellowing on certain materials over time.
- Mixing cleaning chemicals: Never combine bleach with vinegar, ammonia, or other cleaners.
To keep pillows whiter longer
- Use pillow protectors under pillowcases.
- Wash pillowcases regularly.
- Avoid letting hair products, oils, or lotions soak into the pillow.
- Air out pillows occasionally.
A clean pillow is important for comfort and hygiene, but whitening alone does not mean the pillow is “new”—support and condition matter too.
