Metal outdoor sofa legs are prone to rust due to constant exposure to moisture, rain, and humidity. To keep them looking new and extend their lifespan, follow these effective rust-prevention methods:

1. Regular Cleaning – Dirt and debris trap moisture, accelerating rust. Wipe down metal legs weekly with mild soap and water, then dry thoroughly.

2. Apply Protective Coatings – Use rust-resistant sprays, paint, or clear sealants designed for outdoor metal. Powder coating is another durable option.

3. Use Rust Inhibitors – Products like WD-40 or specialized rust inhibitors create a barrier against moisture. Reapply every few months.

4. Elevate with Protective Pads – Place rubber or plastic caps under the legs to minimize direct contact with wet surfaces.

5. Store Properly in Off-Season – If possible, cover or store furniture indoors during heavy rain or winter months.

By following these steps, you can significantly reduce rust formation and keep your outdoor sofa looking great for years.
