| Tarnished Copper Information |
Polish with a commercial polish for copper following directions on the container.
Polish can be made at home by moistening salt with vinegar or lemon juice to make a paste for a bright finish or a paste of rottenstone and olive oil for a dull finish.
After polishing decorative items, spray with lacquer to preserve color if desired.
The "bronze disease" also attacks copper. Use hot vinegar and salt, or lemon juice and salt, copper cleaner, or buttermilk to remove these patches of corrosion. After treating, wash promptly with soap and water, rinse and dry.
