PROBLEM TO BE SOLVED: To provide a method of grinding an internal surface of a metallic hollow container with which the internal surface of the metallic hollow container can be ground in a short period of time within a few hours by a simple method, the internal surface of the container does not get rusted without coating, and absorbed water can be reduced. SOLUTION: An upper surface of a grinding medium 2 is covered with water 3 to be poured into an internal space of the metallic hollow container 1, wherein a total volume ratio of the grinding medium 2 and the water 3 poured into the internal space of the container 1 occupying the internal space of the container 1 is 12.5-60%. The internal surface of the container 1 is ground by rotating the container 1 at peripheral velocity of 50-150 m/min around an axis 4 in a state that the axis 4 of the container 1 is inclined with respect to its vertical direction.
