How to Restore and Maintain Antique Copper Kettles

Antique copper kettles are more than just beautiful kitchen decor—they’re treasured pieces of history. Whether you’ve just purchased one from our vintage copper collection, inherited a family heirloom, or discovered one at a flea market, you may be wondering: How do I restore and care for an antique copper kettle without damaging it?

Together, lets walk through how to clean, restore, and maintain your vintage copper so it retains its charm and lasts for years to come.

⸻

1. Assess the Condition First

Before doing anything, take a good look at your copper kettle:

• Is there a tin or stainless steel lining inside?

• Are there green spots (verdigris), dents, or signs of corrosion?

• Is the kettle purely decorative, or do you plan to use it? (See our blog on safety!)

These answers will determine how far you should go with cleaning and restoration. For example, lined kettles can be cleaned more gently if you plan to use them. Decorative pieces can tolerate deeper polishing.

2. Clean the Surface Safely

The first step is removing dirt and buildup:

• Mix warm water with mild dish soap.

• Use a soft sponge or cloth to gently wipe down the exterior.

• Avoid abrasive pads or harsh chemicals—they can scratch or strip patina.

If the piece has been sitting for years, you may need to repeat this process a couple of times.

3. Remove Tarnish (Only If You Want To)

Some collectors love a polished look, while others prefer the aged patina. If you choose to polish:

Try this natural copper cleaner:

• Mix equal parts lemon juice and baking soda or salt to make a paste.

• Rub gently with a soft cloth, then rinse and dry.

You can also use a commercial copper polish—just make sure it’s non-abrasive and safe for antiques. Avoid polishing the interior if it has a tin lining, as you could damage the protective coating.

4. Handle Verdigris with Care

Verdigris (the greenish-blue corrosion that forms on copper) is a sign of moisture exposure. While it looks rustic, it’s toxic if ingested and should be removed if you plan to use the kettle.

To remove verdigris:

• Use a soft cloth soaked in vinegar, or

• Try a cotton swab with lemon juice and salt.

Rinse thoroughly and dry immediately.

5. Prevent Future Tarnish

Once clean, you can slow down future tarnishing:

• Dry the kettle completely after each use or cleaning.

• Store it in a dry, cool place.

• Rub with a little mineral oil or beeswax to create a protective barrier (especially if it’s just for display).

6. Re-Tinning the Interior (If Needed)

If your copper kettle has a worn or damaged tin lining, and you want to use it for boiling water, consider professional re-tinning. This restores the kettle’s safety and functionality.

It’s not always necessary for display items, but for functional use, it’s worth the investment.
