Abstract

In a method of cleaning and refurbishing a process chamber component having a metal coating having a surface thereon, the surface of the metal coating is immersed in an acidic solution to remove at least a portion of the process deposits from the surface. Thereafter, the surface of the metal coating is immersed in a basic solution to remove substantially all the metal coating. The component may optionally be bead blasting to roughen a surface of the component, and the metal coating may be re-formed.
