Outdoor sofa cushions can often develop an unpleasant sterilized or musty smell due to moisture, mold, or improper storage. Here are some practical tips to keep them fresh and odor-free:

1. Regular Cleaning: Wash your cushions with mild soap and water every few weeks. Avoid harsh chemicals, as they can leave a sterilized odor. Allow them to dry completely in the sun before using or storing.

2. Proper Storage: When not in use, store cushions in a dry, well-ventilated area. Use breathable storage bags instead of plastic to prevent moisture buildup.

3. Use Vinegar or Baking Soda: For natural deodorizing, lightly spray cushions with a vinegar-water solution or sprinkle baking soda. Let it sit for an hour before brushing off.

4. Sunlight Exposure: Sunlight kills mold and bacteria. Occasionally air out your cushions in direct sunlight to eliminate odors.

5. Waterproof Covers: Invest in waterproof cushion covers to protect against rain and humidity, reducing the risk of mildew.

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