Abstract
A process for blast cleaning an article having internal passageways that produces a clean, weldable, and brazable article that is free of blast media residue. The process includes blasting the internal passageways of the article with a soluble blast media, rinsing the article with a solvent in which the blast media is soluble, and removing the solvent from the internal passageways of the article using a stream of air.
