How to Wash Yellowed Pillows: 3 Tips to Get Them Clean Again
Yellowing is usually caused by sweat, body oils, saliva and moisture accumulating over time. You can often improve the appearance, but an old pillow may not return to its original bright white.
1. š§ŗ Check the care label first
Before washing, check whether the pillow is machine washable. Many polyester and some down/feather pillows can be washed, while some memory-foam and latex pillows should not be put in a washing machine. For foam pillows, follow the manufacturer’s cleaning instructions.
2. š«§ Use a suitable laundry detergent
For a washable pillow, use a small amount of regular laundry detergent and the warmest water permitted by the care label. An oxygen-based laundry whitener can help with yellowing if the manufacturer permits it.
Avoid using excessive detergentāit can leave residue inside the filling.
3. āļø Rinse thoroughly and dry completely
Run an extra rinse if necessary, then dry the pillow completely according to its care instructions. Incomplete drying can leave moisture trapped inside, encouraging odors and potentially mold growth.
For machine-dryable pillows, periodically stop the dryer and redistribute the filling so it dries evenly.
ā ļø Never mix cleaning chemicals
Don’t combine chlorine bleach with vinegar, ammonia or other household cleaners. Dangerous fumes can result. If you use a commercial whitening product, follow its label rather than creating a stronger homemade mixture.
Tip: A washable pillow protector underneath your pillowcase can significantly reduce future yellowing by keeping sweat and oils from reaching the pillow itself.
