Pros and Cons of Dishwasher Cleaning

When it comes to cleaning your copper cups, using the dishwasher can be a convenient option. However, there are some important factors to consider before placing them in the dishwasher.


  • Efficient Cleaning: Dishwashers offer a hands-free cleaning solution, saving you time and effort.
  • Sanitization: High temperatures in dishwashers can help sanitize your copper cups effectively.
  • Convenience: Simply load the cups into the dishwasher and let it do the work for you.
  • Risk of Discoloration: Harsh detergents and high heat in dishwashers can cause copper cups to discolor.
  • Damage to Finish: Frequent dishwasher use may harm the beautiful finish of your copper cups over time.
  • Potential Pitting: Copper is a soft metal and may pit when exposed to the harsh conditions in the dishwasher.

Remember, while the dishwasher can be a time-saver for cleaning certain items, hand-washing your copper cups with a mild detergent and soft cloth is often the best way to maintain their beauty and longevity.

How Dishwashers Affect Copperware

When you decide to put copper cups in the dishwasher, it’s essential to understand how this decision could impact your beloved copperware. Here’s how dishwashers can influence your copper cups:

  • Heat and humidity: Dishwashers expose your copper cups to high temperatures and moisture, increasing the likelihood of discoloration over time.
  • Harsh detergents: The strong detergents commonly used in dishwashers can be abrasive on the delicate surface of copper, potentially leading to finish damage and pitting.
  • Other items: Copper cups may come into contact with other dishes and utensils in the dishwasher, risking scratches and nicks that can detract from their appearance.

Consider these factors when deciding whether to clean your copper cups in the dishwasher or opt for a gentler hand-washing method.

Alternative Cleaning Methods for Copper Cups

When it comes to maintaining your copper cups, sometimes hand-washing is the way to go. Here are a few alternative cleaning methods to keep your copper cups looking their best:

  • Vinegar and Salt: Create a paste with equal parts vinegar and salt. Apply it to the cup, let it sit for a few minutes, then rinse well.
  • Lemon and Baking Soda: Sprinkle baking soda inside the cup, add a splash of lemon juice, and gently scrub. Rinse thoroughly afterward.
  • Ketchup: Yep, you read that right! The acidity in ketchup can help remove tarnish from copper cups. Apply, let sit, then rinse.

Remember, gentle cleaning methods can be just as effective as the dishwasher, without the risk of damage.


Remember, when it comes to cleaning your copper cups, it’s best to avoid the dishwasher. Opt for gentler methods like hand-washing with mild soap and water or using natural cleaners like vinegar, lemon, or ketchup. These alternatives can help preserve the beauty of your copper cups without the risk of damage. So, next time you reach for your favorite copper cup, give it some extra care and attention to keep it shining for years to come.
