Abstract:

A cleaning method involves, in a first step, emitting a first laser light toward the surface of a steel material targeted for cleaning to clean the surface of the steel material. Next, in a second step, a second laser light is emitted toward the surface of the steel material to remove an oxide layer formed on the surface of the steel material due to irradiation with the first laser light. In this step, the oxide layer formed on the surface of the steel material is removed, by emitting the second laser light at a power in a range that does not cause a new oxide layer to form on the surface of the steel material.
