    Water reacts with aluminum over time. The inside of aluminum cans have always been lined. Same with aluminum water bottles and cans. If your aluminum water bottle is old and makes water taste funny, get a new one–the lining is probably shot.

      If the aluminum is old, it formas a patina of aluminum hydroxide/aluminum hydride/aluminium oxide that stabilizes it somewhat.

      People often don’t know - because water autoionizes, it is both an acid and a base. This is why so many things can readily dissolve in it.
