PROBLEM TO BE SOLVED: To provide a saturation method for a belt-like thin plate capable of suppressing the crystallization of a residual chemical liquid halfway in saturation, effectively utilizing a treatment liquid, and reducing the load of wastewater treatment.SOLUTION: A washing method for a belt-like thin plate comprises a treatment step for performing the treatment of a belt-like thin plate 2 in a treatment tank 11 using a treatment liquid, a pre-washing step of diluting a treatment liquid remaining on the surface of the belt-like thin plate 2 having passed through the treatment tank 11 by wiping in a pre-washing tank 12 filled with a saturation steam, a main washing step of saturation the belt-like thin plate 2 having passed through the pre-washing tank 12 with washing water, and a reflux step of refluxing the wiping treatment liquid wiped off from the belt-like thin plate 2 in the pre-washing step into the treatment tank 11.SELECTED DRAWING: Figure 1 【課題】洗浄途中における残留薬液の結晶化を抑制すると共に、処理液を有効活用することが可能であって、排水処理の負担も低減できる、帯状薄板の洗浄方法を提供すること。【解決手段】処理液を用いた処理槽１１で帯状薄板２の処理を行う処理工程と、処理槽１１を通過した帯状薄板２の表面に残る処理液を、飽和水蒸気が充填された事前洗浄槽１２内で払拭することで希釈する事前洗浄工程と、事前洗浄槽１２を通過した帯状薄板２を洗浄水で洗浄する本洗浄工程と、事前洗浄工程で帯状薄板２から払拭した払拭処理液を処理槽１１に還流する還流工程を、を備える、帯状薄板の洗浄方法。【選択図】図１
