Outdoor sofa cushions can sometimes develop an unpleasant vinegar-like smell, often caused by mildew or bacterial growth due to moisture. Here are some effective ways to keep your cushions fresh and odor-free:

1. Regular Cleaning: Wash your cushions with mild soap and water every few weeks. Ensure they dry completely before placing them back on the sofa.

2. Proper Storage: Store cushions in a dry, well-ventilated area when not in use, especially during rainy or humid seasons.

3. Use Vinegar Solutions: Ironically, white vinegar can help eliminate odors. Mix equal parts water and vinegar, spray lightly on the cushions, and let them air dry.

4. Baking Soda Treatment: Sprinkle baking soda on the cushions, let it sit for a few hours, then vacuum it off to absorb odors.

5. Sunlight Exposure: Occasionally place cushions in direct sunlight to kill bacteria and prevent mildew growth.

By following these simple steps, you can enjoy fresh-smelling outdoor cushions all season long!
