Cast aluminum urban outdoor furniture is prized for its durability, elegant designs, and resistance to rust. However, to ensure it remains beautiful and functional for years, proper maintenance is essential. Regular cleaning is the cornerstone of care. Use a mild soap, such as dish detergent, mixed with warm water and a soft brush or cloth to gently scrub the frame. Rinse thoroughly with a hose to remove all soap residue. For tougher grime or stains, a paste made from baking soda and water can be effective. It is crucial to avoid harsh, abrasive cleaners or steel wool, as these can scratch and damage the powder-coated or painted finish.
After cleaning, always allow the furniture to dry completely. For added protection, especially in harsh climates, applying a protective automotive wax or a specific furniture sealant once or twice a year is highly recommended. This creates a barrier against moisture, UV rays, and pollutants. While cast aluminum is robust, inspecting it periodically for any chips or scratches in the finish is a good practice. Touch up any damaged areas with matching paint to prevent underlying metal exposure.
During extreme winter conditions or for long-term storage, consider moving the furniture to a dry, covered area like a garage or shed. If moving isn't possible, use high-quality, breathable waterproof covers. Unlike wrought iron, cast aluminum will not rust, but it can develop a dull, whitish oxidation layer if neglected, which can be cleaned off. By following these simple steps—regular cleaning, periodic waxing, and proper storage—you can significantly extend the life and preserve the aesthetic appeal of your cast aluminum urban outdoor furniture, making it a lasting investment for your outdoor space.
