How to clean copper properly

One day there comes a point when, as a proud owner of copper mugs, you ask yourself the questions of how to properly clean copper mugs and how to remove copper stains so that the copper mug shines again as it did on day 1.

Because the purer the copper, the sooner and more copper will tarnish over time. This is because copper has the property of reacting with oxygen in the air to form stains.

These stains appear in different shapes and colors, also depending on whether or not water was involved in the reaction. This may not be completely preventable, but can at least be kept to a minimum with proper precautions and a few of our cleaning tips. 

In the following, you will learn how to get your copper mugs or other copper accessories clean again.

Is copper dishwasher safe?

Very important: You should always clean your copper mugs by hand - and never put them in the dishwasher!

Because copper is generally not suitable for dishwashers, as it is very reactive. Cleaning in the dishwasher can even lead to increased discoloration and stains.

Remove oxidation and make copper shine again

The following 3 cleaning methods for copper accessories and copper mugs will ensure that the copper oxidation that has developed over time is removed and the beautiful precious metal will shine again as it did on day 1.

Method 1: Cleaning copper by hand with mild detergent

But you can also get your copper clean quickly without a dishwasher: Use a mild detergent and apply it with a sponge. Wipe the copper in circular motions with the sponge.

Then rinse off the detergent residue with cold or warm water. Rinse until the soap is completely gone.

When drying with a cloth, take good care that each copper cup is completely dry and there is no moisture on any corner or edge. Otherwise, oxidation stains may appear prematurely.

Method 2: Make copper shine again with lemon and salt

To keep your copper mugs from discoloring, you can put 4 tablespoons of salt in a plate. You can use regular table salt, sea salt or any other type of table salt for this purpose. Depending on how many cups you want to clean, you may need more salt.

Now cut a lemon into 2 halves or 4 parts. Depending on how many copper cups you want to clean, you may need two or more lemons.

Now place the lemons on the salt. Make sure the flesh of the lemon is completely covered with salt.

Rub your copper mugs in a circular motion with the lemons.

Scrub the outside and inside of the mugs until all stains are removed and their surfaces shine again.

Now rinse the mugs thoroughly with cold or warm water until all lemon and salt residue is removed.

Dry each mug thoroughly with a cloth. While drying, also pay attention to small corners and edges so that there is no moisture anywhere, otherwise oxidation stains may form again. Be meticulous that your copper mugs are completely dry after rinsing.

Method 3: Remove oxidation stains with vinegar and baking soda.

With vinegar and baking soda can form a paste that gives a toothpaste-like consistency:

To do this, take 3 parts baking soda and mix it with 1 part vinegar. Mix until a paste is formed.

Now apply the paste to your copper with a sponge. Cover both the inside and outside of the mug with the paste.

Let the paste sit for 5 to 10 minutes. The paste should be cured after no more than 10 minutes.

Now you can wipe the paste off with a sponge: to do this, scrub the mugs in a circular motion until all the coating is gone and the surfaces are shiny again.

Rinse the mugs with cold or warm water. Rinse your mugs until all residue from the paste is gone.

Dry each mug thoroughly with a cloth. While drying, also pay attention to small corners and edges so that there is no moisture anywhere. This is very important so that there are no stains. Make sure that the cups are really completely dry. Only in this way you avoid the renewed formation of oxidation spots.
