I am not talking about the battery post in any way, in fact at no point in my post did I even mention the battery as the source or location of the problem. Simply that you need to disconnect the battery before removing the live power terminal at the fuse panel in order to clean it.

I am also not talking about Galvanic corrosion, I am talking about simple oxidation and RUST; aka corrosion.

I also did not suggest that galvanic corrosion is caused by the terminal being loose, I stated that I saw corrosion [at the terminal on the fuse panel that I depicted] AND signs of arcing due to the nut being loose [at same said terminal].

Simple fact is, if the nut is loose on that terminal, it can cause arcing. Arcing can cause holes in any form of coating/plating (zinc/nickel) that resists corrosion/rust. Once this coating/plating is compromised, corrosion/oxidation/rust can form on the surfaces. If left unchecked, this can spread beyond the original point of arcing.
