The Bymat will easily remove the oxide film from the weld quickly, cleanly and safely. Simply dip the pad or brush into the Electrolytic cleaning solution and wipe across the weld. The oxide film instantly disappears and the welded area is simultaneously protected against corrosion (passivated) in one operation. In comparison with cleaning and pickling with acids, this process is significantly faster and less expensive due to zero waiting time. The chemicals used for the process contains no hazardous substances and so is significantly safer than conventional chemical cleaning methods.
