How to Care for Copper Mugs & Barware
Important to know about solid copper
- Copper is a natural, highly conductive material that requires a bit of special care. Do not place your copper mug in the dishwasher or microwave, and avoid using it with hot liquids, as copper can become very hot and may cause burns.
- Over time, copper will naturally react with air, moisture, and the beverages it holds. This process, called oxidation, can cause the surface to darken and develop a patina. This is completely normal and not harmful.
- Because each mug is handcrafted, you may notice slight variations in color or small imperfections in the finish. These details are part of the handmade process and make each piece unique.
In fact, the evolving appearance of your mug is one of the clearest signs that it is made from genuine copper. If copper didn’t change over time, it wouldn’t be authentic.
Signs your copper is tarnishing
When copper is exposed to oxygen, it naturally begins to form a darker layer on the surface. This may appear as:
- Brown or dull areas
- Dark spots
- Black marks
- General discoloration
Certain elements such as sulfur in the air or minerals in water can accelerate this process, sometimes causing parts of the surface to darken more quickly. It’s even normal to notice changes after the first use.
This process, known as oxidation, is completely natural and not harmful. In fact, many people prefer the look of a copper mug that has developed a rich patina over time.
Because this is a normal characteristic of genuine copper and not a defect, tarnishing is not considered eligible for return. For more details, please refer to our Return Policy.
Regular Care for Copper Mugs
Caring for your copper mug is simple and helps maintain both its appearance and longevity.
- Hand wash only using warm water and a mild dish soap
- Dry immediately with a soft cloth to help prevent water spots
- Do not place in the dishwasher or microwave
- Avoid soaking for extended periods
The interior of the mug is raw copper, so it is safe to gently scrub the inside as needed to remove residue. The exterior is coated with a protective lacquer to help preserve its finish, so it’s best to avoid abrasive scrubbers or harsh materials on the outside, as they can cause scratching.
With regular care, your copper mug will continue to perform well and maintain its intended finish over time.
Removing tarnish from copper mugs
Removing Tarnish from Copper Mugs
Copper mugs require minimal upkeep, but over time they will naturally tarnish as the metal reacts with oxygen in the air. If you prefer to restore the original shine, there are several effective ways to remove tarnish.
Metal Cleaner
The most reliable method for removing tarnish is a metal cleaner specifically designed for copper. These cleaners are formulated to break down oxidation quickly and safely, and many can also be used on metals like sterling silver, brass, and stainless steel. You can use a product like Midas Touch Copper Polishing Cream or any copper-safe cleaner available at your local hardware store.
DIY Cleaning Methods
If you need a quick solution, a few common household ingredients can also help remove tarnish.
Lemon & Salt
- Place several tablespoons of salt in a small bowl
- Cut a lemon into quarters
- Dip the cut side of the lemon into the salt, coating it well
- Gently scrub the mug in circular motions using the lemon
- Once the tarnish is removed, stop scrubbing and rinse
- Wash and dry the mug as outlined in the care instructions
Vinegar & Baking Soda
- Mix 3 parts baking soda with 1 part vinegar to form a paste
- Apply the paste to the mug using a soft sponge
- Let it sit for 5–10 minutes
- Gently scrub in circular motions with warm water to remove
- Finish by washing and drying the mug as outlined in the care instructions
