It's not corrosion, it's oxidisation. -Clean it off with a good metal polish such as Dura-Glit.
If it isn't a smooth polished surface, use a brass bristled brush or wire wheel attachment for a dremel tool. If it is a smooth polished surface, use a dremel with a buffing wheel and a metal polish of some type. Brasso and Excite are examples of a metal polish that will work on bronze. You can actually use plain white toothpaste, but it doesn't work as well.
When bronze is exposed to water and oxygen, it can form a patina or green layer on its surface called bronze disease. This is a result of a chemical reaction between the metal and the water, leading to corrosion. It is important to keep bronze objects dry to prevent this from happening.
Drinking out of a bronze cup is generally safe, as bronze is a non-toxic material. However, be cautious if the cup is very old and shows signs of corrosion or has a patina, as these can contain harmful substances. It's best to clean the cup thoroughly before use.

Bronze is a mixture of copper and tin. And is pretty resistant to corrosion. Bronze is already a mixture, so 100% is a bit meaningless.
A mixture of copper and tin is called bronze. It is an alloy that is known for its strength and corrosion resistance.
Bronze can develop a blue-green patina over time due to a process called oxidation. This occurs when the surface of the bronze reacts with moisture and carbon dioxide in the air, forming a layer of copper carbonate (often called verdigris) on the surface. The patina not only changes the color of the bronze but also helps protect it from further corrosion.
Resists corrosion and doesn't rust, 70% copper, 30% tin.
Ammonia can corrode aluminum by forming an aluminum ammine complex that can weaken the metal. It can also cause stress corrosion cracking in aluminum. On bronze, ammonia can tarnish the surface and cause pitting corrosion by attacking the copper content in the alloy.
In some situations, controlled corrosion can be advantageous. For example, the green patina that forms on bronze statues over time is considered a desirable aesthetic feature by some people. This natural corrosion process can enhance the appearance and value of the statue, rather than being seen as a negative impact.
Clean it with a mixture of baking soda and water.
Bronze is an alloy composed mainly of copper as the solvent and tin as the solute. The tin is dissolved in the copper to create the bronze alloy, giving it its distinctive properties such as increased strength and corrosion resistance.
