Living near the coast offers beautiful views and fresh ocean air, but the salty, humid environment can be brutal on metal outdoor furniture. The constant exposure to salt spray and moisture accelerates corrosion, leading to unsightly rust that compromises both the aesthetics and structural integrity of your pieces. However, with proactive care and smart choices, you can significantly extend the life of your metal urban outdoor furniture.
The first and most crucial step is prevention through material selection. If you're purchasing new furniture, opt for inherently rust-resistant metals. Aluminum, particularly powder-coated aluminum, is an excellent choice for coastal areas as it doesn't rust. Stainless steel (grade 304 or better yet, marine-grade 316) is also highly resistant to corrosion. For existing furniture, the key is to create a barrier between the metal and the corrosive elements.
Start with a thorough cleaning regimen. Rinse your furniture with fresh water at least once a week to remove salt deposits and moisture. Every month, wash it with a mild soap solution and a soft brush. Ensure the furniture is completely dry afterward.
Applying a protective barrier is essential. For wrought iron or steel furniture, use a automotive or marine-grade wax or a furniture protectant spray designed for metal. Reapply this protective coating every few months, especially after heavy rain or storms. For furniture with painted or powder-coated finishes, promptly touch up any chips or scratches with matching paint to prevent moisture from reaching the bare metal.
Consider using specially formulated anti-corrosion sprays or corrosion inhibitors like those used in marine environments. These products create a thin, protective film that displaces water. Placing your furniture under a covered patio, using protective furniture covers during storms or the off-season, and ensuring good airflow around the pieces can drastically reduce moisture retention.
For furniture already showing signs of rust, address it immediately. Remove surface rust with a wire brush or sandpaper. Treat the area with a rust converter, which turns rust into a stable, paintable surface. Then, prime with a rust-inhibiting primer and repaint with a high-quality, rust-resistant paint.
By implementing these strategies—choosing the right materials, maintaining a consistent cleaning schedule, applying protective coatings, and addressing damage promptly—you can enjoy your stylish metal urban outdoor furniture for years to come, even in the challenging coastal environment.
