摘要：
A process for producing an aluminum wheel includes a cleaning step, in which the surface of the aluminum wheel is chemically etched with an alkali cleaning liquid which contains an alkali builder, an organic builder, and a chelating agent to such an extent that the Si atomic ratio of metal Si to oxide Si is from 0.01 to 9, and a shot blast treatment step can be omitted for cleaning the surface of the aluminum wheel.
