How to Clean Copper and Prevent Copper from Tarnishing Again
Plated jewelry continues to age with time. Some of you LOVE the look of the darkening that naturally happens, others of you, not so much.
How to Clean Copper!
After doing some research on how to clean copper, Cheryl took an afternoon and conducted 5 tests using household ingredients.
Here are the 5 tests that Cheryl conducted and the brief description of the results.
1. Lemon Juice & Salt!
Mix together 1 tbs lemon juice and 1 tbs salt. Rub on the components with your fingers or a cloth. Rinse with warm water and dry.
Results: This technique brightened the copper quite quickly and easily. Very little rubbing needed.
2. Vinegar & Salt!
Mix together 1 cup vinegar and 1 tbs salt. For best results, submerge the tarnished copper into the vinegar and salt solution for 5 minutes.
Results: Removed tarnish nicely.
3. Baking Soda & Salt!
Cover the inside of a bowl with aluminum foil. Pour 1 tbsp baking soda and 1 tbsp salt into the bowl. Fill half way with hot water. Mix contents and submerge the jewelry for 10 minutes. Rinse and dry.
Results: This technique removed a little of the tarnishing; however seems to be less effective than the other methods.
4. White Vinegar & Salt!
Mix together 1 cup white vinegar and 1 tbsp salt. Pour the mixture into a medium sized pan and submerge the copper findings. Bring the mixture to a boil. Boil for 60 seconds. Remove, rinse and dry.
Results: “I was blown away by the results. This brightened the copper quite well. I declare this as the winner”.
5. Ketchup & Water!
Lightly cover the piece with ketchup and let sit for a few minutes. Let the ketchup sit for a few minutes. Rub vigorously with a non-scratch pad or cloth. Wash with water and dry.
Results: This technique was also a surprise. I used a paper towel for the wiping and rubbing. The bracelet brightened up very well and with very little rubbing.
All of the tests worked to clean the copper and remove the darkening, but the copper soon returned to its tarnished state. Copper just naturally does that, dang it! In order to keep the copper plating bright, you will want to apply a coating to prevent the copper from tarnishing. Read on!
Prevent Copper from Tarnishing!
If you want the Nunn Design Findings to not darken as they age, there is a solution. The product to use is ProtectaClear*.
Step 1:
ProtectaClear recommends that you then wipe the finding with a solvent wipe right before applying the coating. Honestly, I’m not sure what a solvent wipe really is or what to recommend. What I did use was a Pro-Polish Polishing Pad to gently clean the metal.
Step 2:
I wasn’t doing a full production run, so I just coated the ProtectaClear on with a natural bristle brush. If doing a large amount of findings, the instructions recommend that you place the findings on a piece of foil. You can also use a sponge-brush to apply the coating on both sides of the findings. There is also a spraying method that you can do.
Step 3:
Let the finding fully cure. This can take 4-5 days.
*I want to provide full disclosure about this blog post. Nunn Design does not sell or gain any financial benefit for promoting this product. I have purchased it and tested it, but my recommendation comes from numerous long time customers that have used this product exclusively. ProtectaClear comes to me highly recommended and I’m passing on the knowledge that I know.

Great testing Cheryl! I have found after cleaning copper pieces or before they tarnish to rub some Renaissance Wax on them. I have had success with this & it is going on a year plus that the pieces have stayed tarnish free!

Thank you Joan! We will have to explore that option.
We use Nikolas Spray. It’s a clear lacquer, used by musicians for their instruments. You spray it on, and let it dry. Generally dries within a few minutes, full cure in 24 hours. You have to use it outside. It is non-toxic when dry. Also better to spray two (or three) thin coats rather than one thick coat.
Thank you Elizabeth! We will research that too!
Thanks, for all the tips. I wear a copper bracelet daily, I do not remove it rarely. I found the baking soda worked well.
Do you know if Protectaclear works with copper chainmaille? I add your components and would love to have one product for both
