Outdoor sofa cushions can sometimes develop a strange vinegar-like odor, often caused by mildew or bacterial growth due to moisture. Here’s how to keep them fresh and odor-free:

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

2. Proper Drying: After cleaning or rain, ensure cushions dry completely before placing them back. Sunlight helps kill bacteria.

3. Use Vinegar Spray: Ironically, a diluted white vinegar solution (1:1 with water) can neutralize odors and prevent mildew. Spray lightly and let dry.

4. Store Properly: When not in use, store cushions in a dry, ventilated area. Use breathable storage bags to avoid trapping moisture.

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

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