A fuel tank cleaning ball serves for attracting metal impurities within a fuel tank, and has a function of checking whether the fuel tank is dirty. The fuel tank cleaning ball comprises an enclosing body made of non-magnetic material, but the magnetic lines can pass through the enclosing body, an outer surface of the enclosing body being uneven and rough, having sags and crests so as to expand an area of the outer surface for attracting impurities; a magnetic metal sheet enclosed within and fixed by the enclosing body; the magnetic lines emitting from the magnetic metal sheet can pass through the enclosing body so as to attract the impurities within the fuel tank. Amount of impurities on the fuel tank cleaning ball is used to decide whether an interior of the fuel tank is dirty.
