The TIG Brush® is a safe and effective way to clean the surface of stainless steel, particularly after welding. It has been designed to quickly remove blue and brown iron oxide marks without altering the surface finish of the metal. TIG Brush® also passivates the metal in the same operation, producing a complete result very quickly. The fluid used with the TIG Brush® is activated at high temperatures, and is therefore relatively safe for the operator and the environment under normal conditions.
