Most of the corrosion you are seeing is galvanic corrosion. It's because there are two different metals (or similar metals of different alloy), in contact with one another.
If by chance an electrolyte like water gets into contact with one of the metals, the one with the metal more likely to oxidize will.


The water that comes out of our taps is very hard, and has many electrolytes which can support galvanic corrosion, a final rinse with RO or distilled water can help remove the ions which support corrosion. Also drying is an important factor, as it helps to remove the water which is acting as the electrolyte.


tldr, the salt from saltwater is polar and is removed/dissolved by water which is also polar.
