No, you should not use regular furniture polish on your metal outdoor furniture. While it might seem like a quick way to add shine, most regular polishes are formulated for indoor wood surfaces and can actually harm your outdoor metal pieces. These polishes often contain oils, silicones, or waxes that can attract dust, dirt, and pollen, creating a sticky surface that is difficult to clean. More importantly, they can break down the factory-applied protective coatings on the metal, stripping its defenses against rust and corrosion from rain and humidity. For aluminum or steel furniture, this can lead to premature weathering and expensive damage.
Instead, proper care for metal outdoor furniture involves simple cleaning with a mild soap and water solution. For routine maintenance, mix a few drops of dish soap with warm water, use a soft brush or cloth to scrub the surface, and then rinse thoroughly. To protect the metal and maintain its finish, specifically look for protectants labeled for outdoor metal use. These products are designed to shield against UV rays and moisture without leaving a residue. For wrought iron, a coat of automotive wax can provide a protective barrier, while a specialized metal protectant is best for powder-coated aluminum. By using the correct products, you will extend the life and beauty of your outdoor investment, keeping it looking great for many seasons to come.
