Tiffany is a sleek and durable outdoor middle table made of electrostatic powder-coated aluminum, perfect for patios, decks, or gardens.. To maintain its quality, avoid dragging the furniture, standing water on its surface, and always use covers when not in use for extended periods. For daily care, clean regularly with a soft towel and mild soap; avoid harsh or abrasive cleaners to preserve the powder-coated finish. A 1:1 solution of white vinegar and water can help remove water spots—always rinse and dry thoroughly.
