Gold-plated jewelry and cutlery are in no way inferior in appearance to products made from pure gold. However, during use, it often happens that spoons and forks, earrings, bracelets, pendants and chains lose their shine and become noticeably dull. But there are ways to clean gold plating and restore it to its original appearance at home.
How is gilded silver produced? Why does gold plating turn black?
The coating has a minimum thickness of no more than 2 microns. This opportunity became possible thanks to the development of a technology called electroplating. In this case, the product is immersed in the solution along with a fragment of gold. When an electric current is passed, yellow metal ions are electrodeposited onto the silver. This is facilitated by the correct choice of electrolyte. Previously, a cyanide solution was used. However, it causes great harm and contains a dangerous substance. Later the method was improved and a non-cyanide electrolyte was used.
The standard of silver with gilding does not change. For example, if you need to coat a 925 alloy, then even after electrodeposition of yellow metal ions, the main characteristics remain the same. The standard of gold-plated silver is 925. But the coating protects the jewelry from tarnishing only for a limited period. Causes of blackness:
- contact with sweat due to illness, taking medications, excessive physical activity;
- exposure to cosmetics and detergents;
- violation of storage rules - in a room with high humidity;
- damage: where there are scratches, patina appears on the silver faster.
Which silver to choose to clean less often
Ag is a soft metal that quickly loses its original shape and color. It needs to be carefully looked after, often polished and cleaned of dirt. To reduce costs (time, physical), different methods are used. One of them is gilding, but even in this case, the silver can darken in areas where the coating has become thinner.
It is recommended to choose a precious metal with the least amount of ligature. For this, alloys 925 and 960 are considered.
The absence of identifying marks on gold-plated silver most often indicates that the product is of poor quality. Most likely it's costume jewelry. It will quickly lose its shape. This kind of thing won't last long. But sometimes the absence of a sample indicates that the product has been repaired. You can determine whether a piece of jewelry is worthy of attention by contacting a jeweler.
Salt
This method will not help get rid of stubborn stains, but will return the product's shine and lightly clean the metal.
- 200 ml of water is poured into the pan.
- Add 1 tsp. salt.
- The solution is placed on gas and heated.
- Products are immersed in it, brought to a boil and boiled for 15 minutes.
After this, jewelry and cutlery should be rinsed and polished with suede.
How to clean gilding on silver so that it does not peel off. Preparing your jewelry for cleaning
Products with complex configurations (watches, bracelets, chains) are best disassembled if possible. It is advisable to perform such actions if there are pendants. They are removed because in the areas where the links are attached, the coating is darker first (subject to mechanical stress). Then they continue preparing for cleaning, because you need to remove greasy stains and dust:
- processing with lint-free rags, using microfiber, flannel: the dry method is welcome, but most often surface dirt cannot be removed, so it is permissible to slightly moisten the rag;
- applying alcohol or turpentine - this method is used if there are difficult stains on the gilded silver.

A little history
Cupronickel as such does not exist in nature: in fact, it is a group of compositions made of copper with the addition of nickel, iron, zinc, manganese and some other metals. Most often it is an alloy of copper and nickel, which has its own specific features and properties. According to historical sources, it was invented in China in the 8th century BC and given the sonorous name “pakfong”. All attempts to unravel the composition of “Chinese silver” by European alchemists were unsuccessful: only by the beginning of the 19th century did mass production of nickel silver begin in Germany. At first, the European nobility considered such dishes to be “the dishes of the poor,” and therefore still preferred dishes made of other metals - gold and silver. Only by the 20th century did production increase its speed everywhere. The attractive appearance of cupronickel was used to make cutlery, candlesticks, jewelry and other decorative elements. Wear-resistant, easy to maintain and not too expensive, the alloy is appreciated and actively used in household use.
Interestingly, psychologists consider cupronickel tableware to be beneficial for the psyche. The unobtrusive, calm, noble shine of the alloy calms the nervous system, relieves tension and sets you to a calm rhythm.
Why methods for silver and gold are not suitable
Silver, gold and precious metal plating are materials with different properties. Even gold plating can behave differently than gold, which is due to the small thickness of the surface layer, a combination with Ag. When products designed for one type of metal are used for other purposes, they often damage the jewelry.
You should choose universal semi-professional products; the label should indicate that the product is suitable for cleaning gold and silver.
How to clean gold-plated silver at home quickly and effectively with stones
Most available products are usually recommended for cleaning certain products. If there is a stone on the jewelry (pearl, emerald, cubic zirconia, etc.), so that it does not become cloudy, but shines, such items should not be soaked or cleaned with soda. Toothpaste, boiling water, as well as acids and alkalis are other options that can harm inserts on jewelry. If you are choosing a method for cleaning gold-plated silver, you should consider the most suitable options:
- soap solution: detergent is dissolved in warm liquid, a silver item with gold plated is rubbed with the product, then rinsed with water;
- semi-professional special preparations: when choosing, you should read the composition; in the case when you need to clean jewelry with stones from darkening, you need to consider not only products for silver and gold (universal), first of all, purchase those of them whose label says that it is acceptable care for stones on jewelry.
CARE OF GOLD-PLATED PRODUCTS
To decorate dishes and stainless steel souvenirs, they are often coated with pure gold (24 carats), in the form of stripes and patterns, which naturally significantly increases the cost of the dishes. Abroad, 100% gold is classified as 24 carat fineness, which in Russia is designated as 1000 fineness. Gold is applied using the galvanic method and it is technically impossible to cover the product with gold of a lower fineness.
Cleaning of gold-plated products is carried out in various ways:
- To remove dirt from a gold-plated surface, you need to wipe it with a cotton swab dipped in turpentine.
- The tarnished surface of a gold-plated item can be refreshed by gently wiping it with a flannel cloth moistened with a mixture consisting of 1 tablespoon of liquid “Whiteness” and 1 egg white.
Old tips for cleaning gilding:
- It is necessary to clean gilding (especially on wood) very carefully. First, remove all dust from the gilding, then wipe the gilding carefully with a soft sponge or cotton wool slightly moistened with alcohol of wine or turpentine.
- To clean gilding, you can also use strong beer or a mixture of ammonia (10 parts) and soap solution (40 parts).
- A good remedy: egg whites, which you use to carefully wipe the product with a flannel napkin.
- Cover the gold with pure wine vinegar, after 5 minutes, rinse carefully with water and let dry (without wiping with anything).
How to clean a gold plated watch
Gentle methods:
- dry cleaning - done with a lint-free cloth;
- wet processing - you need to soak a cotton pad in water, remove excess water, rinse the watch case;
- toothpaste - apply only to a flat surface, as it can get between the links of the bracelet, from where the product will be difficult to remove.
When none of the methods help, polish the watch using WD40 lubricant.
