Solutions for cleaning oxidised copper

There are various household remedies you can use to clean oxidised copper. While these solutions can sometimes be effective, it is important to know that they do not always deliver the desired results and may carry certain risks. Here are some options you can try:

• Lemon juice and salt: Sprinkle salt over the copper surface, then rub lemon juice over it. Leave the mixture to work briefly before wiping it away with a damp cloth.
• Vinegar and salt: Make a paste from vinegar and salt and apply it to the oxidised copper. Leave it to sit for a few minutes, then rinse with warm water.
• Ketchup: Coat the copper item with ketchup and leave it for around 30 minutes. Then rinse thoroughly with warm water and dry.
• Cola: Soak the oxidised copper in cola for a short period, then rinse with water and dry thoroughly. Use this carefully, as acidic drinks can affect some finishes.

Be aware that these methods may not always deliver the desired results and that using them is at your own risk. Acidic household methods may damage lacquered, plated or delicate copper surfaces. For the best results and to prevent damage to your copper items, HG recommends using specially formulated copper cleaning products.

Causes of oxidised copper

Copper is a versatile metal often used because of its excellent conductive properties and attractive appearance. Unfortunately, copper is also prone to oxidation, which can cause the metal to discolour and become dull over time. The main causes of oxidised copper are:

• Exposure to air and moisture: Copper reacts with oxygen and moisture in the air, creating an oxidation layer.
• Contact with sulphur: Sulphur-containing substances, such as sulphur in food or in the air, can accelerate copper oxidation.
• High temperatures: Exposure to high temperatures can speed up the copper oxidation process.
• Lack of regular maintenance: If you do not regularly clean and maintain copper, oxidation can build up and become harder to remove.

To prevent copper oxidation in future, regularly clean the metal with a suitable cleaning product and keep it dry. Also protect copper from exposure to sulphur-containing substances and high temperatures. With regular maintenance, you can keep your copper items looking beautiful and shiny for years to come.
