You can effectively clean pure copper using a homemade paste of salt, flour, and vinegar.
Here's a breakdown of the process:
Materials You'll Need:
- 1/4 cup salt
- 1/4 cup flour
- White vinegar (enough to make a thick paste)
- Soft cloth or sponge
- Warm water
- Clean, dry cloth
Steps for Cleaning Copper:
-
Prepare the Cleaning Paste: In a bowl, mix the salt, flour, and vinegar. Add vinegar gradually until you achieve a thick, paste-like consistency.
-
Apply the Paste: Using a soft cloth or sponge, apply the paste evenly to the surface of the copper item you want to clean.
-
Rub and Polish: Gently rub the paste onto the copper, focusing on areas with tarnish or discoloration. Use a circular motion.
-
Buff to Shine: Continue rubbing the paste until the copper begins to shine. This may require some elbow grease, especially for heavily tarnished items.
-
Rinse Thoroughly: Rinse the copper item completely with warm water to remove all traces of the paste.
-
Dry Immediately: Use a clean, dry cloth to thoroughly dry the copper item. This is crucial to prevent water spots and further tarnishing.
Why This Works:
- Salt: Acts as a mild abrasive to help remove tarnish.
- Flour: Helps to thicken the paste and provide a gentle polishing action.
- Vinegar: The acetic acid in vinegar helps to dissolve copper oxide, the compound that causes tarnish.
Important Considerations:
- Test in an Inconspicuous Area: Before cleaning the entire item, test the paste on a small, hidden area to ensure it doesn't damage the copper's finish.
- Avoid Abrasive Scrubbers: Do not use harsh scrubbers or abrasive cleaners, as these can scratch the copper surface.
- For Heavily Tarnished Items: You may need to repeat the cleaning process or let the paste sit on the copper for a longer period (up to an hour) before rubbing.
- Alternative Cleaning Solutions: Lemon juice and baking soda can also be used to create a similar cleaning paste.
By following these steps, you can effectively clean pure copper and restore its original shine.
