Outdoor sofa cushions can develop an unpleasant sulfur smell due to moisture, mildew, or bacterial growth. To prevent this issue, follow these practical steps:

1. Regular Cleaning: Wash cushions with mild soap and water every few weeks. Avoid harsh chemicals that may damage fabric.

2. Thorough Drying: After cleaning or rain, ensure cushions dry completely in sunlight. Moisture trapped in fibers encourages odor-causing bacteria.

3. Proper Storage: Store cushions in a dry, ventilated area when not in use. Use breathable covers to prevent moisture buildup.

4. Vinegar Solution: Spray a mix of white vinegar and water (1:1 ratio) to neutralize odors and inhibit mildew growth.

5. Baking Soda: Sprinkle baking soda on cushions, let sit for an hour, then vacuum to absorb lingering smells.

By adopting these habits, you can keep your outdoor cushions fresh and free from sulfur odors all season long.
