How can I effectively clean copper coated pans to maintain their quality and appearance?

To effectively clean copper coated pans and maintain their quality and appearance, mix equal parts of vinegar and salt to create a paste. Apply the paste to the pan, scrub gently with a soft cloth or sponge, then rinse with warm water and dry thoroughly. Avoid using abrasive cleaners or harsh chemicals, as they can damage the copper coating. Regularly polishing the pan with a copper cleaner can also help maintain its shine and prevent tarnishing.
