Moisture can find its way onto your brass in several ways. Cleaning brass, whether with soap and water, polishing solutions, or other methods, inevitably introduces water to the surface. Even cleaning solutions themselves may leave behind moisture. Exposure to humid environments, accidental spills, or simply storage in a poorly ventilated area can also contribute to moisture buildup. This is why proper drying is so important. By thoroughly removing moisture from brass, you significantly mitigate the risk of tarnishing, corrosion, and other forms of damage, preserving the luster and extending the lifespan of your brass items.
