Copper, a beautiful and versatile metal, is widely used in cookware due to its excellent heat conductivity and aesthetic appeal. However, when it comes to cleaning copper kitchenware, there may be some confusion on whether it is safe to place copper items in the dishwasher. This article aims to address this question and provide guidance on how to properly care for copper cookware.
The Concerns with Placing Copper in the Dishwasher
Copper is a soft metal that can easily react with certain chemicals and elements found in dishwashing detergents. Additionally, the high heat and strong water pressure in dishwashers can damage the delicate patina and cause changes to the appearance of copper items. Therefore, there are legitimate concerns about placing copper kitchenware in the dishwasher.
Chemical Reactions and Corrosion
Dishwashing detergents often contain harsh chemicals, including alkalis and sulfates, that can react with copper. This chemical reaction may lead to corrosion and discoloration of the copper surface. Over time, the beautiful patina that forms on copper cookware can be compromised, affecting both the appearance and functionality of the item.
Mechanical Damage
Besides chemical reactions, the mechanical aspects of dishwashers can also pose a risk to copper. The high water pressure and strong jets can cause dents, scratches, or even deformations to the delicate copper surface. Additionally, items made with other materials such as handles or rivets may not be dishwasher-safe, and the dishwasher’s heat and water pressure can exacerbate these issues.
Proper Care for Copper Cookware
While dishwashers may not be the best option for cleaning copper, there are alternative methods that can ensure your copper cookware maintains its integrity and appearance.
Hand Washing with a Soft Cloth
The safest way to clean copper cookware is by hand with a mild dish soap and warm water. Gently scrub the surface with a soft cloth or sponge to remove any stains or debris. Avoid using abrasive scrubbers or steel wool, as these can scratch the copper. After washing, rinse the item thoroughly and dry it immediately to prevent water spots from forming.
Polishing and Maintaining the Patina
To maintain the beautiful patina of copper, periodic polishing is necessary. There are many copper cleaners available on the market, specifically designed to remove tarnish and restore the shine of copper surfaces. Following the instructions on the cleaner, apply the polish to the copper cookware and buff it using a soft cloth or a sponge. Remember to wear gloves and work in a well-ventilated area when using copper cleaners.
Storing Copper Properly
To prevent your copper cookware from becoming damaged or tarnished while in storage, take some specific precautions. Firstly, ensure the cookware is completely dry before storing it, as moisture can lead to corrosion. Secondly, consider using individual storage bags or felt dividers to prevent items from rubbing against each other and causing scratches. Finally, keep your copper cookware away from humid or damp environments that can accelerate tarnishing.
Placing copper kitchenware in the dishwasher is generally not recommended due to the potential for chemical reactions, corrosion, and mechanical damage. To ensure the longevity and beauty of your copper cookware, it is best to hand wash it with a gentle dish soap and maintain it regularly with proper polishing techniques. By following these care instructions, you can enjoy your copper cookware for years to come and preserve its elegance and functionality.
