How can you restore the finish to calphelon cookware?

To restore the finish of Calphalon cookware, you can start by cleaning it thoroughly with a mixture of baking soda and water to remove any built-up grime or stains. For tough spots, use a non-abrasive sponge or cloth to gently scrub without scratching the surface. If the cookware is non-stick, ensure you avoid using metal utensils or harsh chemicals that could damage the finish. Lastly, applying a small amount of vegetable oil to the surface can help maintain its luster and prevent sticking.
