PURPOSE:To easily obtain a replated steel sheet having excellent adhesion by pickling and surface-grinding a zinc-nickel alloy having a defective appearance under specified conditions, and then replating the steel sheet. CONSTITUTION:A zinc-nickel alloy plated steel sheet having a defective appearance due to uneven plating is degreased. The degreased steel sheet is pickled with a 0.1-0.5% weak hydrochloric acid. The steel sheet is then washed with water, and then the surface is ground with a brush roll. The surface of the plating is replated by the same plating soln. as before.
