Pillows yellow from sweat, body oils, and humidity absorbed over time. A standard wash cycle doesn't touch the deep discoloration. This method does.What you need:— ½ cup baking soda (Arm & Hammer)
— 1 cup white vinegar
— Washer set to 140°F
— 2–3 tennis balls for the dryerMethod:
Place two pillows directly in the drum — loading two at once balances the machine and prevents violent spinning. Pour the baking soda directly into the drum over the pillows.Pour the white vinegar into the fabric softener compartment. It stays there and releases automatically during the rinse cycle, working separately from the baking soda.Run a full cycle at 140°F — hot water is essential for breaking down the oils that cause yellowing. Add an extra rinse cycle if your machine offers it.Transfer immediately to the dryer with 2–3 tennis balls. The balls beat the pillow fill back into shape as it dries and prevent the clumping that makes a pillow unusable. Dry on medium heat until completely dry throughout — a damp center breeds mildew.Check by pressing the pillow firmly — if it feels cool or dense in the center, run another cycle.
