Why does flux residue have to come off?

Because it is mildly conductive and draws moisture, so it creates leakage paths between pads. That is how a repair that tested fine comes back as an intermittent fault weeks later.

What should I clean a board with?

Isopropyl alcohol, ideally 99%, with the board tilted so dissolved residue runs off rather than resettling. Let it dry fully before power goes anywhere near it.
