The invention belongs to the technical field of non-ferrous metal smelting, and discloses a smelting-free crystallized magnesium ingot washing method, which comprises the following steps: step A, selecting a certain amount of crystallized crude magnesium, placing in a refining crucible, heating and melting to form magnesium liquid; b, the magnesium liquid in the refining crucible is further heated to 800-900 DEG C, and the crystallized magnesium ingot is slowly immersed in the magnesium liquid for washing; c, after crude magnesium on the outer layer of the crystallized magnesium ingot is completely melted, high-purity magnesium with the compact interior is obtained; and D, after multiple times of crude magnesium melting, the total amount of the magnesium liquid after washing in the refining crucible is gradually increased, a refining agent is added into the magnesium liquid to refine the magnesium liquid in the refining crucible, finally, the magnesium liquid is poured into an ingot, and the magnesium ingot w
