"Copper mailboxes will make your neighbor's envious. They will not rust, they are extremely attractive, and go along with any type home. Year after year you will have great service from them."
Copper rust is commonly referred to as patina, which is a greenish-blue or greenish-brown film that forms on the surface of copper and other metals when exposed to air over time.
When copper and oxygen react, they combine to form copper(II) oxide. This chemical reaction involves the transfer of electrons from copper to oxygen, resulting in the formation of the compound CuO. Copper(II) oxide is a black solid.
Iron corrodes faster than copper because iron is more susceptible to oxidation in the presence of moisture and oxygen, leading to the formation of rust. Copper, on the other hand, forms a protective layer of copper oxide (patina) on its surface that slows down the rate of corrosion.
The green material on copper is oxidation. On iron or steel it is called rust, on copper and bronze is it called a patina. Unlike the rust on steel and iron that damages the metal, rust on copper, bronze, and even aluminum can protect the under-laying metal. You can even make the green different shades by applying different oxidizers, which some artists use in place of painting the metal.
No, placing dirty copper in distilled water will not clean it. To clean dirty copper, you may need to use specific cleaning agents or methods such as a mixture of vinegar and salt, or a commercial metal cleaner.
"Yes, copper mailboxes are still being used. Because they will not rust and are very durable, they will always remain in style. They will withstand all types of weather while remaining decorative."
Copper mailboxes can be bought at several places out there. One possibility would be for example the page "TheSecretCopperShop". Another great source of copper mailboxes is the shop of "ClasicCopper".

Copper doesn't rust
Any type of rust paint will not adhere to plastic. Rust paint is meant for rusting metals such as mailboxes, railings, and spouting.
Copper corrodes, things made of iron rust. Copper can corrode, but it takes longer than it does for iron to rust.
Rust occurs on iron and steel when they oxidize in the presence of moisture and oxygen. Copper does not rust; instead, it forms a patina when it oxidizes, which is a greenish layer that protects the copper from further corrosion.
Plastic pipe does not rust, brass does not rust, copper does not rust. Stainless steel does not rust, lead pipe does not rust.
The only chemical that could make something rust is iron; "rust" refers specifically to the corrosion of iron, so copper cannot rust. However, its corrosion is caused by copper itself being oxidised and forming compounds which are water soluble and also easier to damage.
Oxygen turns copper green.
copper does not rust
Most likely some other object has dripped rust onto the copper, which can be removed. Copper does not rust, but it does form a green patina over time.
