Your pillow stinks due to bacteria, body oils, and sweat absorbed over time. Unlike the new synthetic memory foam smell, these odors mean it’s time to replace the pillow. Airing out or using baking soda won’t fully resolve the issue. Regular washing or replacing pillows is essential for hygiene.
Regular cleaning mitigates these issues effectively. Firstly, check the care label to ensure proper washing methods. Most pillows are machine-washable and require a gentle cycle with warm water. Use mild detergent; avoid bleach as it can damage the fibers. Adding a cup of white vinegar during the rinse cycle helps eliminate stubborn odors.
Next, dry the pillow thoroughly. Damp conditions encourage mold growth, so a high-heat setting is recommended, along with a few tennis balls to keep the filling evenly distributed. For memory foam or specialty pillows, spot-clean with mild detergent and air them out completely.
Additional maintenance involves using pillow protectors and washing them weekly along with pillowcases. Regular exposure to sunlight also helps kill bacteria. If a pillow retains odor after cleaning, it may be time to replace it.
Consistent cleaning extends the life of a pillow, ensuring hygiene and comfort. Now, addressing the broader context, maintaining a clean sleep environment also involves proper care of mattresses and bedding.
