How to Wash Yellowed Pillows: 3 Tips to Make Them Fresh and White Again

Yellowing is often caused by sweat, body oils, skin products and accumulated soil. The good news is that many washable pillows can be refreshed—but always check the care label first. (American Cleaning Institute)

1. 🧺 Wash with detergent and the hottest safe water

Check the pillow’s care instructions, then wash with a good laundry detergent using the hottest temperature permitted for the fabric and filling. Don’t overload the washer; the pillow needs room to move and rinse properly. (American Cleaning Institute)

2. ✨ Use oxygen bleach for stubborn yellowing

For pillows labeled safe for it, oxygen/color-safe bleach can help brighten fabric and is generally gentler than chlorine bleach. Follow the product directions rather than guessing the concentration. (American Cleaning Institute)

Chlorine bleach isn’t suitable for every material and can actually cause discoloration or damage to certain fabrics. (American Cleaning Institute)

3. ☀️ Dry the pillow completely

After washing, dry according to the care label and make sure the inside is completely dry before putting the pillow back on the bed. A damp pillow can develop an unpleasant odor and potentially encourage mold or mildew.

⚠️ One important warning

Never mix chlorine bleach with vinegar, ammonia, or other household cleaners. Dangerous fumes can result. (American Cleaning Institute)

Bottom line: For a washable pillow, the best approach is proper detergent + the hottest safe wash + oxygen bleach when appropriate + thorough drying. If the pillow is old, badly stained, lumpy, or no longer holds its shape, replacing it may be more practical than trying to restore it.
