How to Prevent Copper from Tarnishing

Quck answer

Copper tarnishes over time due to oxidation, but there are several ways to prevent or slow down this process:

1. Keep copper clean and dry: Wipe copper items regularly with a soft cloth to remove dust and moisture.

2. Apply a protective coating: Use a clear lacquer or wax to create a barrier between the copper and the air, preventing oxidation.

3. Store copper items properly: Keep copper pieces in airtight containers or bags to minimize exposure to air and moisture.

4. Avoid direct contact with skin: The natural oils and acids in our skin can accelerate tarnishing. Wear gloves or handle copper items with a cloth.

5. Use anti-tarnish products: Store copper items with anti-tarnish strips or silica gel packets to absorb moisture and slow down tarnishing.

By following these simple steps, you can keep your copper items looking shiny and beautiful for longer.


There are numerous products available in the market that can clean and polish copper, but there are also simple steps that homeowners can take to maintain the shine of copper objects for a long time. It’s good to know that you don’t need harsh chemicals to make your copper look like new. With just a few common household ingredients, anyone can clean and polish almost any copper item. Additionally, preserving the pristine appearance of copper is as simple as protecting it from air and oils.

Step 1

Combine 3 cups of concentrated lemon juice with 1 cup of salt. Stir until all the salt has dissolved.

Step 2

Dip a sponge into the lemon juice and salt mixture, and vigorously rub it on a tarnished copper item. In many cases, this will be sufficient to remove years of tarnish and restore the golden shine of the copper item. If the tarnish persists, add one cup of white vinegar to the lemon and salt mixture and try again. If the tarnish still doesn’t come off, add 1/2 cup of ammonia to the lemon/salt/vinegar mixture and attempt once more.

Step 3

Before applying the cleaning mixture to your copper item, wear gloves and give it a final wipe. Pay special attention to cleaning any areas that your fingers or other exposed skin have touched. Rinse the copper item thoroughly while wearing gloves. Avoid touching the clean copper item with your fingers or any exposed skin, as the oils from your skin can cause the copper to tarnish almost immediately.

Step 4

Apply a light coat of lacquer to all exposed copper, ensuring that you don’t touch the copper object with your bare fingers. Allow the object to dry for a minimum of 2 hours or follow the instructions on the lacquer can. If needed, spray one side of the copper object, let it dry, and then spray the other side. Allow the entire object to dry for at least 2 hours or as per the manufacturer’s instructions.
