Bronze

Bronze is an alloy of copper, and is of a bright gold appearance after polishing. With time, it will normally turn a darker shade of brown or green depending on its environment. Although this oxidation process is a form of corrosion, the resultant oxide film is less reactive than bronze and forms a stable, protective barrier. It is therefore very common to let the bronze age, letting it ‘weather’ naturally to give the bronze an authentic old look. However, areas containing high levels of sulphur or chlorine should be avoided, since they will adversely accelerate corrosion.

Cleaning Methods
1) Clean bronze using a common dish detergent
2) Wash off detergent with hot water
3) Cover the bronze with a thin layer of wax
4) Allow the wax to dry for 10 min and then buff with a cloth rag
5) Repeat step 3 and 4 using less wax

Maintenance
The maintenance of bronze should consist of cleaning and re-waxing. Outdoor bronze should be maintained 2 to 4 times a year, depending on the climate conditions.
