PURPOSE: In A DI can surface treatment, it is intended to prevent adjacent cans in each of a plurality of partitioned rows from getting into contact with each other so as to eliminate defects such as irregular wash and thus improve quality of can bodies such as the adhesion of coatings to be applied. CONSTITUTION: For treating the inner and outer surfaces, inverted DI cans are fed on a conveyer with partitioners in a plurality of rows such that they are spaced apart in each row, and treatment liquid is sprayed against the travelling cans from above and below the center of each row. It is sprayed from above in a uniform and a full-corn pattern greater in area tan the top surface of the can and from below also in a full-corn pattern or in a fan-shaped pattern narrow in the conveyer width direction and greater in length than the can open end diameter. It is further sprayed against the travelling cans from side nozzles on the opposite sides of and symmetric with respect to the center of each row. The side wall of cans is thus washed without contract of adjacent cans in the progress direction. Washing force is increased in the space between adjacent cans in the progress direction to permit uniform surface treatment of the inner and outer surfaces of cans without washing irregularities.
