The shine can be restored to copper after burning by removing the layer of oxidation and soot that forms on the surface. Several methods can be used, each effective in varying degrees depending on the severity of the burning.
Methods for Cleaning Burned Copper
Here are a few effective methods for cleaning burned copper and restoring its shine:
1. Vinegar and Salt Solution
This is a common and effective household remedy.
- Preparation: Mix equal parts vinegar (white vinegar works best) and salt (table salt is fine) to create a cleaning solution. The salt acts as a mild abrasive.
- Application: Apply the mixture to the burned copper surface.
- Cleaning: Gently rub the surface with a soft cloth or sponge. For stubborn stains, allow the mixture to sit for a few minutes before scrubbing.
- Rinsing and Drying: Rinse thoroughly with clean water and dry completely with a soft cloth. Drying is crucial to prevent water spots.
2. Lemon Juice and Baking Soda Paste
This method utilizes the acidity of lemon juice and the mild abrasive properties of baking soda.
- Preparation: Make a paste by mixing lemon juice and baking soda. The consistency should be thick enough to apply easily.
- Application: Apply the paste to the burned copper.
- Cleaning: Gently scrub the surface with a soft cloth or sponge.
- Rinsing and Drying: Rinse thoroughly with clean water and dry completely.
3. Commercial Copper Cleaners
For heavily burned or tarnished copper, commercial copper cleaners are often the most effective option.
- Selection: Choose a copper cleaner specifically designed for removing tarnish and oxidation.
- Application: Follow the instructions on the cleaner's packaging carefully.
- Cleaning: Typically, you will apply the cleaner, let it sit for a specified time, and then buff the copper.
- Rinsing and Drying: Rinse thoroughly with clean water and dry completely.
4. Boiling and Vinegar Solution
This method is particularly useful for cleaning copper items that can be submerged.
- Preparation: Fill a pot with water and add 1 cup of vinegar per gallon of water.
- Boiling: Bring the solution to a boil and submerge the copper item.
- Cleaning: Let it simmer for 30 minutes to an hour, depending on the severity of the burning.
- Rinsing and Drying: Remove the copper item and rinse thoroughly with clean water. Dry completely.
Important Considerations
- Test in an Inconspicuous Area: Before applying any cleaning solution to the entire surface, test it in a small, hidden area to ensure it doesn't damage the copper.
- Gentle Scrubbing: Avoid using abrasive scrub brushes or steel wool, as they can scratch the copper.
- Thorough Drying: Always dry the copper completely after cleaning to prevent water spots and further tarnishing.
- Protective Gear: When using commercial cleaners, wear gloves and eye protection to avoid skin and eye irritation.
