CoCr Cleaner is an acidic bath used for cleaning and deoxidizing cobalt/chromium alloys to render them suitable for medical and aerospace applications. It removes weld or laser scale leaving a brilliant finish, without hydrogen embrittlement or halide-induced stress cracking. CoCr Cleaner will attack base metal very slowly, and in the process polish the metal. CoCr Cleaner may also be used as a chemical polish for 300 series stainless steel. It is more reactive towards stainless steel than on CoCr.
