How and what to clean brass at home: methods and materials for cleaning.

Metal products made using brass are distinguished by their original color and unusual brilliance. But over time, brass is able to lose its decorative properties, since under the influence of air, metal oxidizes. This process leads to discoloration, stains and loss of gloss of the product. Therefore, often beautiful ornaments have to be cleaned in a secluded place.

To prevent this, brass products must be properly looked after. And it is not necessary to immediately contact a specialist or apply harmful chemicals. How and how to clean brass at home, we will try to understand this article.

A bit of history

Brass is a metal obtained from an alloy of copper and zinc, and the ratio of one unit of copper to two units of zinc is standard. Also, manganese, nickel, tin, aluminum, and lead can be added to the composition. The inclusion of these components significantly changes the properties and color of the alloy.

Despite the fact that people learned about brass before our era, the main component of the alloy, zinc became known only in the 16th century. Even in ancient Rome, on the basis of an alloy of copper with zinc ore, household utensils and various decorations were made.

Brass accessories were imported to Russia from Central Asia, where production of products from this alloy was also arranged. These items and decorations were highly valued by the nobility for their unique color, brilliance and high enough quality. Since 1746, when zinc was discovered, brass also appeared.

Brass application

Brass alloys are often called eternal metal, because products from this material are highly resistant to wear. Thus, an alloy with a 20 percent content of zinc, a two-component type, is widely used in the automotive industry for the manufacture of spare parts. Such an alloy is widely used in heat engineering, due to which a large number of valves are made of brass.

Various pipes and springs are made from multicomponent brass, which are widely used in aircraft and shipbuilding. And the high resistance of the material to magnetic attraction has found its application in the manufacture of compasses. To protect against rust, cast brass spraying is used.

And, of course, brass alloys are widely used in jewelry production. So, a good brass jeweler, which includes 5% aluminum and 15% zinc, is able to create products that are very difficult to distinguish from gold jewelry.

Preparing brass for cleaning

Before cleaning brass at home, it is necessary to perform a number of preparatory operations:

  2. The determination of the age of the brass product is of no small importance, since the alloy was previously treated with special protective compounds. Such means allowed to create a protective layer that protected the metal from the harmful effects of negative factors.
  3. The practical step in preparing brass for the cleaning process is to remove contaminants from its surface. This is done with a soapy solution or detergent. The workpiece is lowered into the solution for 20 minutes, and then cleaned with a brush.
  4. Another important step is the removal of varnish from the surface of the product. For this purpose, you can use nail polish removers. The most gentle way is to immerse the product in hot water. In this case, the metal expands, and then cooling narrows it, and the varnish exfoliates.
