Cleaning a zinc outdoor table requires gentle yet effective methods to preserve its unique finish. Start by removing loose dirt with a soft brush or cloth. Mix a mild soap solution (like dish soap) with warm water, then gently scrub the surface using a non-abrasive sponge. Avoid harsh chemicals or steel wool, as they can damage the zinc's patina. For stubborn stains, a paste of baking soda and water can be applied sparingly. Rinse thoroughly with clean water and dry with a microfiber cloth to prevent water spots. To maintain its shine, apply a thin layer of car wax or specialized metal polish occasionally. Regular cleaning every few weeks will keep your zinc table looking elegant and rust-free for years. For heavily weathered tables, consider consulting a professional restorer to avoid irreversible damage.
