can copper mugs go in the dishwasher

Copper mugs are popular for their aesthetic appeal and their ability to keep drinks cold, making them a favorite choice for cocktails like the Moscow Mule. However, owning these stylish mugs comes with specific care instructions to maintain their beauty and functionality. One common question among copper mug owners is, “Can copper mugs go in the dishwasher?” In this comprehensive guide, we’ll explore the best practices for cleaning and caring for your copper mugs, ensuring they remain in excellent condition for years to come.

The Nature of Copper

Copper is a soft, malleable metal that reacts with various substances, including water, oxygen, and acids. This reactivity gives copper its unique properties but also makes it susceptible to tarnishing and corrosion. Therefore, understanding how to properly care for copper is crucial to maintaining its luster and longevity.

Dishwasher: Friend or Foe?

While dishwashers are convenient for cleaning many types of kitchenware, they are not suitable for copper mugs. Here’s why:

1. Harsh Detergents: Dishwashing detergents are formulated to remove tough grime and grease, which can be too abrasive for copper. These harsh chemicals can strip away the protective lacquer (if your mugs are coated) and accelerate tarnishing.
2. High Temperatures: The high heat inside a dishwasher can cause copper to warp or discolor. Copper is sensitive to temperature changes, and the intense heat can damage the metal, leading to unsightly blemishes or structural integrity issues.
3. Water Spots and Residue: Dishwashers often leave water spots or mineral residue on dishes. These spots can be particularly noticeable on copper and may require additional cleaning to remove.

Proper Cleaning Techniques for Copper Mugs

To keep your copper mugs looking their best, follow these simple hand-washing steps:

1. Gentle Soap and Warm Water: Use a mild dish soap and warm water to clean your copper mugs. Avoid using abrasive sponges or brushes that can scratch the surface. A soft cloth or sponge works best.
2. Rinse Thoroughly: Ensure all soap residue is rinsed off completely. Soap residue can cause tarnishing over time.
3. Dry Immediately: After washing, dry your copper mugs immediately with a soft cloth. Leaving them to air dry can result in water spots and tarnish.

Polishing and Maintenance

Regular polishing helps maintain the shiny appearance of copper mugs. Here are a few tips:

1. Commercial Copper Polish: Use a high-quality copper polish available at most hardware or kitchen stores. Follow the instructions on the product for the best results.
2. Homemade Cleaning Solutions:

• Lemon and Salt: Cut a lemon in half, dip it in salt, and rub it on the copper surface. The acid from the lemon and the abrasive nature of the salt help remove tarnish.
• Baking Soda and Vinegar: Make a paste with baking soda and vinegar. Apply it to the mug, let it sit for a few minutes, then scrub gently with a soft cloth and rinse.

1. Avoid Prolonged Exposure to Acids: Acidic substances like citrus juices, vinegar, and tomato-based products can cause copper to tarnish. Rinse your mugs immediately after exposure to these substances.

Long-term Care Tips

1. Storage: Store copper mugs in a dry place. Moisture accelerates tarnishing, so ensure they are completely dry before putting them away.
2. Lining: Some copper mugs come with a stainless steel or nickel lining, which can help prevent tarnishing and make cleaning easier. Check the manufacturer’s instructions for care specific to lined mugs.
3. Periodic Maintenance: Regularly inspect your copper mugs for signs of tarnish or damage. Addressing these issues promptly will help maintain their appearance and functionality.

Conclusion

While copper mugs should not be placed in the dishwasher due to the risk of damage from harsh detergents and high temperatures, proper hand-washing and regular maintenance can keep them looking beautiful for years. By following these care tips, you can enjoy the aesthetic and functional benefits of your copper mugs while preserving their integrity. Remember, the extra effort in cleaning and maintenance is well worth the longevity and appeal of these elegant drinking vessels.
