Abstract
An aqueous solution ( ) of an alkali hydroxide is stored and held in a tank ( ). An electrode ( ) is disposed in the tank ( ), and a member ( ) coated with a Ti-derived film is disposed in the tank ( ) so as to be surrounded with the electrode ( ). In this state, a power source ( ) applies a negative potential to the electrode ( ) and a positive potential to the member ( ) to flow electricity between the electrode ( ) and the member ( ) immersed in the aqueous solution ( ). Thus, the Ti-derived film coated on the surface of the member ( ) is chemically removed by the aqueous solution ( ).
