Oxidation is a natural process that occurs when copper is exposed to oxygen and moisture. This results in the formation of a layer of copper oxide on the surface of the metal. While this layer can protect the copper from further corrosion, it can also give the metal a dull and unsightly appearance.
There are a number of different methods that can be used to clean oxidized copper. One common method is to use a vinegar and salt solution. To do this, simply mix equal parts white vinegar and salt in a bowl. Then, apply the solution to the oxidized copper using a sponge or cloth. Allow the solution to sit for a few minutes, then rinse it off with clean water. Another common method for cleaning oxidized copper is to use a commercial copper cleaner. These cleaners are typically made with a mild acid, such as phosphoric acid, which helps to dissolve the copper oxide. To use a commercial copper cleaner, simply follow the directions on the product label.
Once you have cleaned the oxidized copper, it is important to protect it from further oxidation. This can be done by applying a clear sealer to the metal. There are a number of different sealers available, so be sure to choose one that is specifically designed for copper.
1. Vinegar and salt
Vinegar and salt is an effective solution for cleaning oxidized copper because it is a mild acid. The acid in the vinegar helps to dissolve the copper oxide, while the salt helps to remove any dirt or debris. This method is best suited for mild oxidation, as it is not as strong as some commercial copper cleaners.

How to use vinegar and salt to clean oxidized copper:
- Mix equal parts white vinegar and salt in a bowl.
- Apply the solution to the oxidized copper using a sponge or cloth.
- Allow the solution to sit for a few minutes, then rinse it off with clean water.
-
Benefits of using vinegar and salt to clean oxidized copper:
- It is a simple and inexpensive method.
- It is effective at removing mild oxidation.
- It is safe for use on most types of copper.
-
Limitations of using vinegar and salt to clean oxidized copper:
- It is not as effective as some commercial copper cleaners.
- It can be harmful to some types of copper, such as lacquered copper.
Overall, vinegar and salt is a simple and effective solution for cleaning mild oxidation from copper. It is important to test the solution on a small area first to ensure that it does not damage the copper.
2. Commercial copper cleaner
Commercial copper cleaners are more powerful than vinegar and salt solutions and are therefore better suited for cleaning heavily oxidized copper. These cleaners typically contain a mild acid, such as phosphoric acid, which helps to dissolve the copper oxide. Commercial copper cleaners are also more effective at removing dirt and debris than vinegar and salt solutions.
-
Benefits of using commercial copper cleaner:
- More effective at removing heavy oxidation.
- Can also remove dirt and debris.
- Easy to use.
-
Limitations of using commercial copper cleaner:
- Can be more expensive than vinegar and salt solutions.
- May not be suitable for use on all types of copper.
Overall, commercial copper cleaners are a more powerful and effective option for cleaning heavily oxidized copper. However, they can be more expensive than vinegar and salt solutions and may not be suitable for use on all types of copper. It is important to test the cleaner on a small area first to ensure that it does not damage the copper.
3. Clear sealer
A clear sealer is an essential component of “How to Clean Oxidized Copper” because it protects the copper from further oxidation. Oxidation is a natural process that occurs when copper is exposed to oxygen and moisture, resulting in the formation of a layer of copper oxide on the surface of the metal. While this layer can protect the copper from further corrosion, it can also give the metal a dull and unsightly appearance.
A clear sealer helps to prevent the formation of copper oxide by creating a barrier between the copper and the elements. This barrier prevents oxygen and moisture from reaching the copper, thereby preventing the oxidation process. Clear sealers are typically made from a synthetic resin, which is applied to the copper in a thin layer. Once the sealer has dried, it forms a tough, protective coating that is resistant to weathering and wear.
In addition to protecting the copper from oxidation, a clear sealer can also enhance the appearance of the metal. Clear sealers can help to restore the copper’s natural shine and luster, and can also help to prevent the metal from tarnishing. Clear sealers are available in a variety of finishes, so you can choose a finish that matches the desired look of your copper.
Overall, a clear sealer is an important component of “How to Clean Oxidized Copper” because it helps to protect the copper from further oxidation and enhances the appearance of the metal.
