Outdoor sofa cushions are prone to developing a rotten smell due to moisture, mold, and mildew buildup. To keep them fresh and odor-free, follow these practical tips:

1. Regular Cleaning: Wash cushions with mild soap and water every few weeks. Use a brush to scrub away dirt and debris, then rinse thoroughly.

2. Proper Drying: Always let cushions dry completely in the sun after cleaning or rain. Flip them to ensure both sides dry evenly.

3. Use Waterproof Covers: Invest in waterproof or quick-drying cushion covers to protect them from rain and humidity.

4. Store Properly: When not in use, store cushions in a dry, ventilated area. Avoid leaving them outside during prolonged wet weather.

5. Vinegar or Baking Soda: For stubborn odors, spray a mixture of water and white vinegar or sprinkle baking soda on the cushions, then wipe clean after a few hours.

By following these steps, you can extend the life of your outdoor cushions and keep them smelling fresh all season long.
