Outdoor sofa cushions can develop an unpleasant ammonia-like odor due to moisture, mildew, or bacterial growth. To prevent this issue, follow these practical tips:

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

2. Proper Drying: Ensure cushions dry completely after rain or cleaning. Sun-drying helps kill bacteria but avoid prolonged exposure to prevent fading.

3. Use Covers: Protect cushions with waterproof covers when not in use to shield them from rain and humidity.

4. Ventilation: Store cushions in a well-ventilated area or use breathable storage bags to prevent moisture buildup.

5. Baking Soda Trick: Sprinkle baking soda on cushions, let it sit for an hour, then vacuum to neutralize odors naturally.

By adopting these habits, you can keep your outdoor cushions fresh and odor-free all season long.
