You can help copper stay shiny by applying a light coat of oil after cleaning it to seal it from the air and slow down the tarnishing process.
Here's a more detailed breakdown:
Preventing Copper Tarnish
Copper tarnishes because it reacts with oxygen and sulfur compounds in the air. To keep it shiny, you need to prevent or slow down this reaction. Here's how:
-
Cleaning First: Copper starts to tarnish immediately after cleaning. It is crucial to clean it first with a suitable copper cleaner.
-
Applying a Protective Barrier (Oil): A thin coating of oil creates a barrier between the copper and the environment, preventing oxidation and slowing tarnish.
- Types of Oil: Baby oil and mineral oil are commonly used due to their clarity and relative inertness.
- Application: After cleaning and drying the copper, apply a very thin layer of oil with a soft cloth. Buff lightly to remove any excess.
-
Other Protective Measures:
- Lacquer or Sealant: For items that won't be used with food, you can apply a clear lacquer or sealant designed for metals. This provides a more durable barrier than oil.
- Proper Storage: Store copper items in airtight containers or bags when not in use to minimize exposure to air and humidity.
-
Regular Cleaning: Despite preventative measures, copper will eventually tarnish. Regular light cleaning helps maintain its shine.
In summary, cleaning your copper and then applying a thin layer of oil, lacquer or sealant is a key step in keeping it shiny. Other methods such as proper storage also help maintain the luster.
