Cleaning the Prius hybrid battery buss bars

The prius hybrid batteries have been having cronic issues with the copper buss bars between modules getting corroded by Potasium Hydroxide weeping through the terminal seals. The effect is a crust of hard material that is non conductive, eventually causing battery failure.
I want to build up more of the 48V modules for my EV's, and wanted to find a way to clean the strips more efficiently than sanding and using steel wool, which can take as much as several minutes of hard work each.
I remembered my Dad showing me how to make old copper pennies shine buy dunking them in muriatic acid (Hydrochloric acid). I still had a container of the stuff which can be bought at most hardware stores, so I gave it a try. It immediately causes the crust to dissolve in a flory of bubbles, and then it stops, and the strip is mostly shiny copper. A thorough wash in running water finishes the job by washing off all the acid. Time will tell as to how it look a year from now, but it looks good now.
