Mildew smell on outdoor sofa cushions can be unpleasant and stubborn, but with the right approach, you can eliminate it effectively. Here are the best methods to restore freshness to your cushions:

1. Vinegar Solution: Mix equal parts white vinegar and water in a spray bottle. Lightly spray the affected areas and let it sit for 15-20 minutes before scrubbing with a soft brush. Rinse thoroughly and air dry. Vinegar’s acidity kills mildew and neutralizes odors.

2. Baking Soda Paste: Create a paste using baking soda and water. Apply it to the mildew-stained areas, let it dry, then brush it off. Baking soda absorbs odors and lifts stains naturally.

3. Sunlight Exposure: Place the cushions in direct sunlight for several hours. UV rays help kill mildew spores and reduce musty smells. Flip the cushions to ensure even exposure.

4. Essential Oils: Add a few drops of tea tree or lavender oil to water and spray the cushions. These oils have antifungal properties and leave a pleasant scent.

5. Commercial Cleaners: Use a mildew-specific cleaner for tough cases. Follow the product instructions carefully to avoid damaging the fabric.

Prevent future mildew by storing cushions in a dry place or using waterproof covers. Regular cleaning and proper ventilation will keep your outdoor cushions fresh and inviting.

By following these steps, you can enjoy mildew-free, pleasant-smelling outdoor cushions all season long.
