If you own copper items, you've probably noticed they develop a green patina called verdigris.
Removing it restores their beauty and prevents surface damage over time. As someone who's used these methods on family heirlooms, I can vouch for their effectiveness.
My grandmother passed down these reliable, natural techniques for cleaning oxidized copper—all inexpensive and safe.
Here are 10 expert tips for removing verdigris from copper. See how:
At the first signs of verdigris, soak your copper item in a baking soda solution. Line a basin with aluminum foil, add 2 tablespoons of baking soda, and pour hot water over it.
Immerse the item for at least 15 minutes. Watch the color change as the patina lifts away.
Rinse with mild soapy water (Marseille soap works best), then dry thoroughly. The copper regains its original luster.
Lemon juice excels at cutting through oxidation. Cut a lemon in half, sprinkle salt on one half, and rub the verdigris vigorously.
A good scrub ensures a spotless finish. Rinse with clean water and dry completely.
