Keeping your outdoor sofa cushions fresh and free from a mildewy smell requires regular care and maintenance. Here are some effective tips to help you achieve this:

1. Store Cushions Properly: When not in use, store cushions in a dry, well-ventilated area. Avoid leaving them outside during rainy or humid weather.

2. Use Waterproof Covers: Invest in waterproof covers to protect cushions from moisture, which is a primary cause of mildew.

3. Clean Regularly: Wipe down cushions with a mild soap solution and let them dry completely before storing or using them again.

4. Allow for Airflow: Ensure cushions have space to breathe by not stacking them tightly. Prop them up occasionally to air out.

5. Use Vinegar or Baking Soda: For mild mildew odors, spray a mixture of white vinegar and water or sprinkle baking soda on the cushions, then brush off after a few hours.

6. Sun-Dry Cushions: Occasionally place cushions in direct sunlight to kill mold spores and eliminate moisture.

By following these simple steps, you can keep your outdoor sofa cushions smelling fresh and extend their lifespan. Regular maintenance is key to preventing mildew and ensuring comfort.
