The present invention provides a cleaning composition, capable of simultaneously inhibiting the occurrence of corrosion or defects in a circuit material and a barrier metal material used in a circuit board, and effectively removing a metal oxide film or organic residues on the circuit board; and a cleaning method using the cleaning composition. The cleaning composition in accordance with the present invention comprises: (A) one or more compounds selected from the group consisting of fatty acid having a hydrocarbon group with 8 to 20 carbon atoms, phosphoric acid having a hydrocarbon group with 3 to 20 carbon atoms, sulfuric ester having a hydrocarbon group with 3 to 20 carbon atoms, alkenyl succinic acid having a hydrocarbon group with 3 to 20 carbon atoms, and salts thereof; (B) organic acids; (C) water soluble amine; (D) a water soluble polymer; and an aqueous medium. In addition, the cleaning composition has a pH higher than or equal to 9. |
