Electrolytically coated tinplate having defect-free surfaces is prepared by subjecting steel to hot-rolling pickling, cold-rolling to form strip, cleaning, rinsing in an aqueous medium containing a substance in minor concentration that remains on the steel strip and is capable of reacting with carbonaceous material during the batch annealing cycle, winding the strip into a tight coil, batch annealing, temper rolling, cleaning, pickling, and coating with tin by electrolytic means.
