Metal outdoor furniture is durable and stylish, but it's vulnerable to rust when exposed to rain, humidity, and the elements. Preventing rust is key to maintaining its appearance and extending its lifespan. Here’s a practical guide on how to protect your investment.
Start with a clean slate. Before applying any protectant, thoroughly clean your furniture. Mix mild dish soap with warm water. Use a soft brush or cloth to scrub away dirt, debris, and any early signs of corrosion (like white, chalky residue). For tougher grime, a paste of baking soda and water can be effective. Rinse completely with a hose and let it dry entirely in the sun. Any remaining moisture can trap water under a sealant, leading to more rust.
Apply a protective barrier. Once the metal is clean and bone-dry, the next step is to create a shield against moisture.
* Wax or Oil: For bare, unfinished metal like wrought iron or steel, a car wax or a thin layer of linseed oil can be an excellent moisture barrier. Apply it with a cloth, buff it in, and reapply every few months.
* Rust-Resistant Spray Paint: If your furniture has minor rust spots, sand them away with steel wool or a wire brush first. Then, apply a metal primer designed to stop rust. Finish with several thin coats of rust-resistant spray paint for a durable, protective finish.
* Clear Coat Sealant: For metal you don't want to paint, like some aluminum finishes, a clear acrylic sealer can provide invisible protection. Ensure it is labeled for outdoor use.
The simplest and most effective strategy is to use covers and smart placement.
* Use Furniture Covers: High-quality, breathable, waterproof covers are one of the best investments you can make. They protect furniture from direct rain and sun. Ensure the furniture is dry before covering it to prevent trapping humidity.
* Strategic Placement: Whenever possible, place your metal furniture under a roof, patio, or in a shaded area. This reduces its direct exposure to rain and dew.
Regular maintenance is non-negotiable. Make it a habit to inspect and clean your furniture a few times a year, especially after harsh weather. Touch up any nicks or scratches in the paint immediately to prevent moisture from reaching the bare metal. For stored furniture during winter, clean and cover it, and store it in a dry place like a garage or shed.
By following these steps—cleaning diligently, applying the right protective coatings, using covers, and performing regular maintenance—you can effectively prevent rust and enjoy your beautiful metal outdoor furniture for many seasons to come.
