Copper cups have gained popularity in recent years, not only for their aesthetic appeal but also for their perceived health benefits. Many people enjoy using copper cups for drinking water, cocktails, or other beverages. However, a common question that arises for copper cup owners is whether or not these cups can be put in the dishwasher. In this article, we will explore the different aspects of washing copper cups and determine whether it is safe to clean them in a dishwasher.
Understanding Copper:
Copper is a soft metal known for its excellent heat conductivity and antimicrobial properties. Copper has been used for centuries in various applications, including cookware, jewelry, and even in construction. When exposed to air and moisture, copper develops a natural patina, which adds character and beauty to the metal.
The Concerns with Dishwashing Copper Cups:
While copper is generally a durable material, there are a few factors to consider when it comes to washing copper cups in the dishwasher. The main concerns are heat, harsh detergents, and the effects on the cup’s patina.
1. Heat:
Dishwashers can reach high temperatures during their cycles, especially during the drying process. Copper cups are susceptible to heat, and prolonged exposure to high temperatures can cause the metal to warp, discolor, or even crack.
2. Harsh Detergents:
Most dishwashing detergents are designed to remove grease, grime, and stains from various materials. However, these detergents may contain chemicals or abrasive substances that can tarnish or damage the copper surface of the cups. Additionally, the high pressure of the dishwasher could exacerbate these effects.
Preserving the Patina:
One of the unique characteristics of copper is its development of a patina over time. This patina gives copper items their distinct aged appearance and protects the metal from further corrosion. Some people prefer to preserve the patina on their copper cups, as it adds a vintage charm to these items. Regular contact with harsh detergents and high heat could strip away this patina and diminish the cups’ aesthetic appeal.
Alternative Methods of Cleaning Copper Cups:

1. Handwashing:
Washing copper cups by hand is the safest and most effective method for maintaining their quality. Simply use mild dish soap, warm water, and a soft sponge or cloth to gently clean the cups. Rinse thoroughly, then dry well with a soft towel.
2. Lemon and Salt:
An excellent natural alternative for cleaning copper cups involves using lemon juice and salt. Cut a lemon in half and sprinkle salt onto the exposed flesh. Gently rub this mixture onto the copper surface, ensuring that every area is covered. Rinse the cups well with warm water and dry thoroughly.
3. Copper Cleaners:

Follow the instructions provided with the cleaner, ensuring that it is safe for your specific copper cup.It is generally not recommended to put copper cups in the dishwasher.
