Outdoor sofa cushions can develop an unpleasant, lab-like smell due to moisture, mildew, or trapped dirt. To keep them fresh, follow these simple yet effective tips:

1. Store Cushions Properly: When not in use, store cushions in a dry, well-ventilated area or use waterproof storage bags to prevent moisture buildup.

2. Use Breathable Covers: Opt for breathable, UV-resistant cushion covers that allow air circulation while protecting against rain and humidity.

3. Clean Regularly: Wipe down cushions with a mild soap solution and let them dry completely in the sun to kill bacteria and prevent odors.

4. Apply Fabric Protector: Spray a fabric protector designed for outdoor use to repel water and resist mildew growth.

5. Rotate and Fluff: Frequently rotate and fluff cushions to ensure even air exposure and prevent damp spots.

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