Used in industrial cleaning processes and metal surface treatment, this anionic mixture helps remove oxides and contaminants from metal surfaces prior to plating or coating. The presence of fluorine and chlorine ions enhances reactivity with metal oxides, particularly in aluminum and stainless steel treatment. Nitrate and sulfate components act as stabilizers and conductivity enhancers in electrochemical applications. Nitrite contributes to corrosion inhibition in closed-loop cooling systems when used in controlled concentrations. The blend is also employed in water treatment for adjusting ionic balance and removing scale-forming minerals. Due to its reactive nature, it requires careful handling and neutralization before disposal to prevent environmental contamination.
