Outdoor sofa cushions can sometimes develop an unpleasant, laboratory-like smell due to moisture, mildew, or lack of proper care. Here are some effective tips to keep your cushions fresh and odor-free:

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

2. Proper Storage: When not in use, store cushions in a dry, well-ventilated area. Use breathable storage bags to avoid trapping moisture.

3. Use of Vinegar Solution: Spray a mixture of white vinegar and water (1:1 ratio) on the cushions to neutralize odors and inhibit mold growth.

4. Sunlight Exposure: Sunlight is a natural disinfectant. Periodically place your cushions in direct sunlight to eliminate moisture and odors.

5. Waterproof Covers: Invest in waterproof or moisture-resistant covers to protect cushions from rain and humidity.

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