Does Deionized Water Go Bad?

Deionized water doesn’t spoil the way food does, but it doesn’t stay perfectly mineral-free forever once it is opened. Exposed to air, it slowly absorbs carbon dioxide, and it can pick up traces from dust or a dirty container. Kept sealed, at room temperature and out of sunlight, it stays suitable for household uses for a long time.
