What causes corrosion?
Corrosion is the natural mechanism by which metal returns to its original state of ore. Corrosion of metal is an electro-chemical process. The flow of electrons from high-energy areas of metal to low energy areas through a solution on the surface of the metal, capable of supporting corrosion. Corrosion will not take place without a conducting solution. The solution is called an electrolyte, caused by water, rain, moisture, and humidity. As little as 65% relative humidity will form an electrolyte, which can cause corrosion.
