Outdoor sofa cushions are prone to developing a musty smell due to moisture, humidity, and lack of proper care. Here are some effective ways to keep them fresh and odor-free:

1. Regular Cleaning: Wash cushions with mild soap and water every few weeks. Allow them to dry completely in the sun to kill bacteria and mold.

2. Use Waterproof Covers: Invest in waterproof cushion covers to protect them from rain and dew, which are primary causes of musty odors.

3. Proper Storage: Store cushions in a dry, ventilated area when not in use. Avoid leaving them outside during prolonged wet weather.

4. Vinegar Solution: Spray a mixture of white vinegar and water (1:1 ratio) to neutralize odors and disinfect the fabric.

5. Baking Soda: Sprinkle baking soda on cushions, let it sit for a few hours, then vacuum it up to absorb moisture and odors.

6. Elevate Cushions: Place cushions on elevated surfaces or use breathable storage racks to improve airflow and reduce dampness.

By following these simple steps, you can enjoy fresh, musty-free outdoor cushions all season long.
