The green spots are sometimes called "bronze disease." Here's an article with steps to address bronze disease.

The solution of mixed sodium carbonate (washing soda) with sodium bicarbonate (baking soda) in distilled water is easy and inexpensive to make and is a helpful soak to remove green corrosion and stop its progress. The soaking can be done for a few days at room temperature instead of the hot water method described.

Formula for sodium sesquicarbonate solution:
10.6 g of sodium carbonate (washing soda) and 8.4 g of sodium bicarbonate (baking soda) dissolved in 100 ml of distilled water
