Polish the copper


Copper is found in household, garden and hobbies in a variety of forms and applications. This also presents different challenges in terms of patinated copper surface over time. That's why we've created a guide for you on how best to polish copper.

Copper - the most important metal of humanity

Copper is as familiar to humanity as no other metal. The use of copper was so high even at the end of the Neolithic period that the entire era of the era was called the Copper Age. Consequently, it is only logical that the subsequent period, which dates back to antiquity, is also known as the Bronze Age. After all, bronzes (today) have a minimum copper content of 60 percent. The then most common bronze was the copper-tin alloy.

Copper is still versatile today

Even if the fields of application have changed many times, copper is still in use today as much as over the centuries. Maybe even more, since the positive properties are good for a wide variety of applications. The good thermal conductivity together with the good corrosion protection make copper the perfect piping.

Many media can not harm non-ferrous metal copper

At the same time, many other media such as water, air, gases, oils, etc. can not harm the non-ferrous metal. In addition, there is an electrical conductivity which is correspondingly high, analogous to the thermal conductivity. Copper also has an antibacterial effect. Together with the high conductivity is therefore another typical use as a cookware.

Copper polish with different means

With so many different applications, the natural patina that results can be undesirable. Partially, however, it is desired, so that the artificial aging of copper is often used. However, in this article we want to focus on the cleaning of copper, especially polishing. For this we present different means:

  • metal polishes
  • copper polishes
  • Home remedies such as citric acid, ketchup, salt, baking soda or soda
  • professional polishes with appropriate polishing material

Metal and copper polishes

Copper polishes, one might think, are gentle and efficient at the same time. But in direct comparison with conventional metal polishes, which have released the manufacturers, inter alia, for copper, the best results are achieved with these general metal polishes.

Copper polishes even have a very weak effect. However, just in applications, the price is quite an important criterion. Depending on the manufacturer, the 100 ml metal polish costs up to 5 euros.

Home remedy for the copper polish

Ketchup and salt

Therefore, home remedies are often the better choice. Ketchup is worth mentioning here. However, only ketchup hardly brings any fresh shine. Mixed with salt, on the other hand, the mixture develops a surprisingly good polishing power and can easily keep up with the purchased metal polishes.

Lemon juice or lemon juice and copper

Lemon juice, which itself has dripped only on the copper, quickly shows the aggressive effect of citric acid. This attacks the copper. The copper is literally etched. Therefore, the removal is rather high. In addition, the citric acid does not leave behind this metallic, bright, shimmering red, which is typical of copper. Rather, the color goes after the lemon juice treatment in a strange pink.

Soda, baking soda and acetic acid

With soda, baking soda and some vinegar, on the other hand, you get a similarly good polish of the copper surface as with salt and ketchup. However, the effort required for polishing and the polishing time are significantly longer.

Professional copper and brass polishes with polishing tools

For professional copper and bronze polishing, the following polishes are required:

  • pre-polishing compound
  • High gloss polishing paste (finish)

The corresponding polishing wheels are used for this:

  • Cotton polishing wheels for pre-polishing
  • Flannel high gloss polishing wheels for the finish

Application of professional copper polish

The speeds are set to relatively high, the contact pressure should be medium. So neither too tight nor too light - just with feeling. Such a polished copper surface is polished evenly high gloss. Even large surfaces can be polished so quickly. Since copper is relatively soft, not only is a grinding, at the same time, the copper surface is also compacted in high-gloss polishing.

Tips & Tricks

If the copper surface is beautifully polished metallic in soft light red, the contact with the air or oxygen immediately has an effect. The passivation layer grows very fast. This is nothing but oxidizing the copper surface, which further protects the metal against corrosion.

To prevent this layer from forming, you must seal the copper surface. Explicitly for this metal so-called Zaponlack is used. Thus, the copper is painted or zaponiert. Note, however, that the service life is relatively short and the Zaponlack must be reapplied regularly.

❓ What will vinegar do to copper?

👉 Acidic substances react with the surface of copper, causing it to tarnish and corrode almost instantly. This corrosion is highly soluble, leading to the presence of toxic copper salts in the food. This is why it is not recommended to use copper vessels for foods high in acidity, such as milk, wine, or vinegar.

👉 Fans of sauerkraut can also use their favorite dish juice to clean and polish copper. Mix 100 milliliters of the sauerkraut juice with 600 milliliters of water, add a tablespoon of salt and rub the mixture with a soft cloth on your copper object. After half an hour, clean it with warm water and polish it with a lint-free cloth.

👉 Sprinkle half a lemon with table salt. Cut a lemon in half. Then, sprinkle half the lemon with a generous amount of salt. [1] Rub the lemon onto the copper's surface.
