To restore copper pots to their original shine and luster, you can create a paste using equal parts of salt, flour, and white vinegar.

Copper vessels tarnish by reacting with oxygen in the air (black copper oxide is formed) or by reacting with water (green copper hydroxide is formed, commonly known as VERDIGRIS ; pronounced ver-dee-gree). These substances coat the metal and can be very difficult to remove as they often sit in small depressions in the surface of the metal and they aren't very soluble in water Lemon juice contains citric acid. This reacts with the copper oxide and copper hydroxide to produce copper citrate. This is readily soluble in water and washes off easily, leaving the sparkling and unadulterated shiny copper surface.
Tarnish can be removed from a penny by physical means; however, this tends to damage the coin and would not be an acceptable way of handling antique or valuable items. Tarnish itself consists of a number of copper compounds formed from elements and compounds that copper items come into contact with, even those that exposed only to the atmosphere. Some knowledge of chemistry is important to knowing what these compounds are, and how they might be removed, without damage being done to coins in the process.
