2. Baking Soda and Vinegar Combo

This classic cleaning duo works wonders on fabric. Fill a large basin with hot water and add half a cup of baking soda and half a cup of white vinegar. Soak your pillow for an hour, then launder it as usual. This method helps neutralize odors and break down sweat stains without harsh chemicals.
3. Lemon and Hydrogen Peroxide Mix
Looking for a bleach alternative? Mix half a cup of lemon juice with one cup of hydrogen peroxide in a bucket of hot water. Soak the pillow for an hour, then run it through a regular washing cycle. Sun drying enhances the whitening effect and helps eliminate lingering bacteria.
Final Tips

Always make sure your pillows are fully dry before using them again—dampness encourages mold and mildew. If your pillows are high quality and less than two years old, these treatments can help extend their lifespan and keep your sleep environment fresh and healthy.
