The first step in restoring whiteness is to check the care label. Most pillows, especially those filled with synthetic or feather materials, can be machine-washed on a gentle cycle using warm water and mild detergent. Avoid hot water, which can damage the filling or cause clumping.
For deep stains, pre-soak pillows in a mixture of warm water, baking soda, and white vinegar. This natural combination helps break down oils and remove odor without harsh chemicals. Soaking for about 30 minutes before washing makes a noticeable difference.
When washing, add two tennis balls or dryer balls wrapped in clean socks to the drum. They help maintain pillow shape and prevent clumping during the spin cycle. Run an extra rinse to ensure all detergent is fully removed.
