Today cupronickel is less common. In spite of resemblance with silver, they prefer not to use it or get it only on special occasions. The reason is the rapid loss of festive brilliance. Products darken, stains form on them.

Cause of darkening

Cupronickel is an alloy of metals, one of which is copper. It quickly oxidizes when exposed to moisture. An unaesthetic coating appears on appliances or jewelry. To avoid this trouble, you need to follow the recommendations for the care of cupronickel products:

• do not use chlorine-containing products for washing;
• clean off food residues;
• wipe dry after cleaning;
• store away from moisture.

Cupronickel products cannot be washed in a dishwasher. After such cleaning, they will darken. It is better to clean with hands in warm water with the addition of shavings from laundry soap.

Modern means

If the products have darkened, they can be quickly refreshed. For this, they issue special means for the care of cupronickel items. They come in the form of a liquid, gel or wipes soaked in a special solution. It is enough to follow the instructions indicated by the manufacturer on the packages. Some of the substances can protect objects from moisture by covering them with the thinnest protective layer.

Ordinary kitchen powders and creams are also suitable for cleaning. But they should not contain aggressive components.

homemade recipes

If there was no special tool or use " harmful chemicals»There is no desire, you can use folk remedies.

• Baking soda. It must be moistened to a paste. Apply to a soft cloth and clean the products from darkening.
• Ethanol. It can be replaced with vodka without dyes and flavors. It is enough to moisten the sponge in alcohol and wipe the dark places.
• Ammonia. It is necessary to fill them with objects for 20 minutes. Then rinse well under running water.
• Vinegar. With the same efficiency from blackness, you can use natural apple or 9% essence. One teaspoon of the substance is poured into a glass of water. Cupronickel spoons and forks are treated with the resulting solution.
• Laundry soap. It is necessary to apply on a soft toothbrush and clean the "problem" places.
• Raw egg white. They moisten a napkin and wipe cupronickel. The tool is soft, so it is suitable for products with gilding. It will clean stains without damaging the coating.

Regardless of the chosen cleaning method, cupronickel products must be washed with clean water before and after the procedure. And then wipe dry.

Removing old stains

When you have to clean the old service or the pollution turned out to be too persistent, you can resort to more complex procedures. Cleaning will take time, but the result will be more noticeable.

Eggshell

1. Grind the shells from four chicken eggs and pour into a saucepan.
2. Pour 2 liters of water and put on fire
3. After boiling, add a tablespoon of salt.
4. Dip products from cupronickel into the solution.
5. Boil over low heat until the desired result is obtained (about ten minutes).

Aluminium foil

1. Line the bottom of a frying pan or saucepan with foil.
2. Pour in two tablespoons baking soda and salt.
3. Pour a liter of boiling water and put on fire.
4. After the foam descends, put cupronickel products.
5. After about ten minutes, the foil will begin to blacken, and the products, on the contrary, will become light.

With the help of foil, you can also refresh items made of gold and silver. But the method is not suitable for cleaning a thin coating of these metals. One procedure is enough to process jewelry or small cutlery. Old coins or goblets with a complex pattern will have to be processed several times.

Decoction of potatoes or pasta

1. Boil two or three potatoes or a handful of vermicelli in 1 liter of water in the standard way.
2. Remove the products, and place cupronickel in the broth.
3. Leave for several hours under a closed lid.
4. When the broth darkens, the products will be clean.

For cleaning, cupronickel objects can be placed in carbonated drinks such as Coca-Cola for several hours.

Shine

When all stains and plaque are eliminated, you can return the shine to the products. Polishing will help to give cupronickel shine. It is necessary to take a flannel cloth or other soft napkin. Apply polishing paste on it and treat the surface.
Pasta can be bought ready-made or made independently from the following components.

• Chalk and soap. Chalk powder and soap shavings are combined in a 1:1 ratio. Dilute with water to a paste.
• Chalk and ammonia. One part of chalk and two parts of ammonia solution are mixed to a homogeneous slurry. If necessary, dilute with water.
• Toothpaste and powder. They can be used both separately and mixed.

After polishing cupronickel is washed under running water and wiped dry.

Cupronickel kitchen utensils, found in the kitchens of many housewives, lose their original appearance over time and under the influence of high humidity. In this article we will tell you how to clean cupronickel at home quickly and efficiently. Assembled Ways have already passed the test of time and show the best result.

Devices from cupronickel

This material is a mixture of nickel and copper in certain proportions, although German silver is often called cupronickel - alloys of copper, nickel and zinc. In my own way appearance cupronickel cutlery is very similar to kitchen silver, but there are several differences - increased strength and wear resistance, as well as lower cost. Sometimes such kitchen utensils are covered with silver, which makes them completely indistinguishable from an expensive service.

Unfortunately, this alloy is not without its drawbacks, the main of which is the loss of the original luster and darkening of the metal.

There are several reasons for this phenomenon:

• High humidity in the room where the instruments are stored.
• Incorrect or untimely care for cupronickel.
• Violation of storage conditions of dishes.

The main enemy of cupronickel cutlery is moisture. If after washing the dishes they were not dried with a towel, then the remaining moisture will leave dark spots. Wet rooms have a similar effect, but on a much larger scale.

Advice! If you plan to regularly use cupronickel appliances, then you need to prepare a ventilated place where they will be stored without the risk of darkening.

How to clean cupronickel products

Over time, even if you do not use cupronickel items, they begin to darken and become covered with a film of oxidized metal. The use of such products in the future becomes unpleasant. Next, we will consider in what ways you can remove the oxidized layer and return the dishes to their former shine and cleanliness. Let's start with folk ways.

foil cleaning

This method is one of the easiest and most popular for cleaning many metal objects. To clean your cutlery, you'll need aluminum foil, baking soda, and regular table salt.

The cleaning procedure will be as follows:

Important! During boiling, chemical reactions will occur with the release of an unpleasant odor. We recommend cleaning in a well-ventilated area.

The basis of this method is the redox reaction of metals. The result will be a noticeable lightening. cupronickel spoons, forks and other items. You can also notice that the aluminum foil also changed its color and became much darker.

ammonia cleaning

The method is based on the special cleaning properties of ammonia, which is the main part of ammonia. With its help, not only metal products are cleaned, but other materials, including those on an organic basis.

If you have ammonia on hand, you can perform a quick cleaning with this tool. Spoons, forks and other cupronickel products are poured into a small container and poured with ammonia for 5 minutes.

After that, it is necessary to remove the devices from the active substance, rinse in cold water and wipe dry with a towel. If necessary, the dishes can be polished with a piece of soft cloth.

Egg shell cleaning

Egg shells will help to cope with the darkening of copper-nickel dishes. Its fat helps to significantly lighten cutlery. The cleaning process will look like this:

• We collect 1 liter of water in a saucepan.
• Finely chop the shell from two eggs and add it to the pan.
• Put water on fire and bring to a boil.
• Immerse cupronickel products in boiling water for a few minutes.
• We take the item out of the water, rinse, wipe dry and polish.

If you need to clean a large number of dishes, or it becomes necessary to use more boiling water, then the volume can always be increased, while maintaining the ratio of water and shell.

Garlic cleansing

Garlic husks are highly effective in cleaning kitchen utensils. To get the desired result, it is necessary to boil cutlery in a saucepan along with garlic husks. It should be remembered that its effectiveness depends on the amount of the husk itself and the complexity of darkening.

Note! In order to clean the forks and spoons from difficult stains, you will need a large amount of garlic. Therefore, start collecting garlic peels well before the planned date for cleaning cutlery.

Chalk cleaning

Of course, you do not need to take hard abrasives. For example, metal sponges or sandpaper. They will not help to cope with the problem completely, but will leave scratches on the surface. In the case of silver or gold plating, this approach will result in irreparable damage to it.

Instead, at home, you can use ordinary chalk. It is pre-ground to get rid of solid particles. Then the resulting substance is applied to a suede cloth and wiped with kitchen utensils.

Instead of chalk I often use toothpaste or powder. They are available in every home. The principle of operation is exactly the same - the active composition is applied to a sponge or brush, with which the surface will be cleaned.

Important! Care must be taken when using toothpaste. Some types of pastes contain aggressive substances in their composition that can damage the silver or gold plating during intensive cleaning.

milk cleaning

If you have curdled milk in your kitchen, then do not rush to get rid of this product. It can help get rid of dark spots from cutlery. It is recommended to do this overnight as the reaction will take 8-10 hours.

If there is no curdled milk, but you want to try this method in action, use table vinegar to speed up the reaction. For every liter of milk, 1 tablespoon of vinegar will suffice.

Soda cleaning

Sodium bicarbonate is a cheap and readily available lye found in every kitchen. Baking soda is actively used not only to clean all sorts of contaminants, but also in cooking to perform some chemical reactions. It can also be used for cleaning cupronickel products.

The easiest way is to apply baking soda directly to a sponge or cloth and rub cutlery. In this case, two actions work at once - mechanical action with a soft abrasive and alkaline action with soda. Contamination should quickly be removed, and dark areas will noticeably brighten. However, the result may vary depending on the complexity of the oxidation.

The second way is longer. It is necessary to dissolve 50 grams of baking soda in 1 liter of water and soak cupronickel dishes in this solution. The chemical reaction will begin almost instantly. After soaking in a soda solution, the forks and spoons must be rinsed in cold water and wiped with a towel.

Cleansing with citric acid

It is known that the most effective tool in the kitchen, citric acid is used to combat oxidized metals. In the case of copper-nickel objects, this rule also applies.

To prepare an effective solution, you need 100 grams citric acid for every liter of water. In the resulting solution, you need to boil the dishes for 15 minutes, then rinse them under cold water and dry with a towel.

A common tip is to use fizzy drinks as an alternative. In their composition, they contain orthophosphoric or citric acid, but in a lower concentration. The pH level of such sodas is higher compared to the previously prepared citric acid solution. This means that their effectiveness for solving the problem will be less.

In addition, the composition of such drinks includes a large number of additional substances that do not help in cleaning at all. It is best to use them for their intended purpose.

Cupronickel is an alloy of copper and nickel, sometimes with additions of iron and manganese. There are alloys with the addition of zinc and silver.

Outwardly, this unusual metal is similar to silver, but it can be of different shades - depending on the composition of the alloy. If a little silver is included in the composition, then new cupronickel products can hardly be distinguished from pure silver ones.

Melchior is a very ancient metal that was known as early as the 3rd century BC. In those distant times, an alloy of copper and nickel was called nothing more than "white copper". According to historical evidence, the metal got its name in honor of the sorcerer Melchior, who came to worship the newborn Jesus.

Cupronickel fans admit that they feel especially comfortable in these jewelry. They seem to warm, radiating some special, radiant energy.

The metal adds a sense of balance and stability. Cupronickel jewelry is recommended for people with a soft character, melancholic and controversial natures. This will help them become more decisive, solid, will allow them to keep themselves within strict limits, and work more productively and orderly. But cupronickel gives people who are too rigid in character such qualities as insight, understanding and patience.

Melchior is widely distributed throughout the world. In many countries it is called "German silver", because at one time it was the Germans who produced it in large quantities. Most often, cutlery and jewelry are made from cupronickel. Most of the modern silver-colored coins are made from cupronickel. This is an excellent replacement for silver - the cost of the alloy is lower, the strength characteristics are higher. The mechanical strength of cupronickel is many times higher than silver, which means that jewelry does not deform - such jewelry cannot be demolished for decades.
Melchior has its own special charm. Artists-jewelers create real masterpieces from this energetically powerful and durable metal. A fantastic combination of color and texture are amethyst earrings made of cupronickel. A traditionally recognized classic is turquoise in cupronickel. All shades of agate look very gentle in a cupronickel frame. Noble garnet, sunny citrine, transparent quartz, radiant tourmaline look spectacular in this design.

Cupronickel acts as an excellent natural regulator and has a positive effect on many stones: it improves, enhances and fully reveals their properties. Cupronickel activates stones with calm energy. Too aggressive stones calms, harmonizes their rigid nature. Cupronickel alloy is a very useful filter for natural stones.

Nickel silver earrings and rings in ethnic style look incredibly interesting. With silver or bronze undertones, cupronickel jewelry is very similar to silver or bronze with a patina. They look almost like ancient artifacts that archaeologists find during excavations. Noble and very unusual shade.
A particularly valuable property of cupronickel is its very high anti-corrosion properties. The metal does not rust both in air and in water, including sea water. Corrosion resistance is provided by nickel and iron additives, which are in the alloy. This is a very important quality of the alloy, thanks to which your earrings or rings will retain their original appearance for many years.

The silver-plated surface of cupronickel has not only excellent aesthetic characteristics, but also unique antiseptic properties.

Moreover, gilding is applied both using the sputtering technology and by the plating method - applying a layer by a thermomechanical method with a thickness of at least 1 micron. Plating is more resistant to abrasion than spraying. With a gold coating, cupronickel product retains a golden hue for a very long time, even with intensive daily wear. In addition, such products are non-allergenic and absolutely safe.

Cupronickel jewelry is very easy and simple to clean. You can do it yourself at home. Professionals use special tools for cleaning cupronickel products: all kinds of solutions, pastes, polishes, etc. They can be purchased at jewelry stores.

Pros and cons of cupronickel

Cupronickel is an alloy of copper and nickel, sometimes mixed with other components, such as iron and manganese. In color, it is similar to the third most important noble metal - silver. For this feature, he received another name - "silver of the poor."

It is believed that for the first time an alloy similar to silver appeared in China long before the new era. The alloy was called pakfong and was used to mint coins, create jewelry and other things. Then pakfong came to Europe, where it gained extraordinary popularity. It got ridiculous: pakfong products cost more than silver ones. After all, the Europeans were unaware that a light beautiful metal looks like silver only in appearance, and there is not a grain of it in its composition. precious metal- only copper and nickel, with minor impurities of other metals.

The European birth of the alloy took place in Germany, where it was dubbed nickel silver - "new silver". But then there was a war with Napoleon, during which all the documentation for the promising alloy came to France. After some time, two Frenchmen, Mayo and Chorier, took up the alloy of copper and nickel. Without the slightest doubt, they called the successful metal a new name, in which they combined parts of their surnames - myshor.

But the Germans reared up, protesting against such impudence. Unable to return the name they gave to the metal, they changed the French: instead of myshor, the metal began to be called cupronickel. According to Christian tradition, Melchior was the name of one of the wise Magi who brought gifts to the newborn Jesus in Bethlehem.

Since German terminology has always dominated metallurgy, pakfong-myshor became cupronickel.

Where do black spots come from on cupronickel

Cupronickel is 50% copper - an easily oxidized metal. Despite the fact that the composition of the alloy also includes nickel, manganese and iron, the oxidation process remains unchanged, since these components practically do not affect it. As a result of oxidation, brownish spots appear on the instruments, which darken over time and acquire a blue-black color.

Darkening most often appears due to non-compliance with storage conditions or improper care. It is not recommended to wash copper-nickel appliances in the dishwasher. The metal does not tolerate contact with chlorine or abrasive cleaners. Cleaning products with chlorine cause an oxidation reaction and abrasives scratch the finish.
