Exactly...
Galvanic corrosion, aka bimetallic corrosion, is an
quote:

electrochemical process in which one metal corrodes preferentially to another when both metals are in electrical contact, in the presence of an electrolyte.
NaCl=sodium chloride=salt, as it turns out, is an electrolyte and the sodium from the salt and the aluminum in the pot are the two metals.

Heat up with vinegar that covers the entire bottom of pan than add Liberal amount of baking soda till it cools. Scrub and wash with soap and hot water. Good luck.

This works, I did it with a frying pan and saved it. Took all the black off.

Whatever it is really doesn't matter. You are boiling crawfish. You are then peeling them and eating. Who cares what color the pot is.
