Coke would be my guess, it is the most caustic to metals. (During the covid crisis I had stored a case of coke in 12 oz cans for my vending machines. But since nobody was getting out, I wasn't selling any soda. so the cans sat for over a year. Then they started leaking as the Coke started eating it's way out of the aluminum cans) Nasty stuff it is....
