Is there anyone here who understands the chemistry/physics behind this process? It reminds me of a similar "simple way to clean silverware" that went around several decades ago... until a chemist explained that it removed the tarnished silver, instead of converting the tarnished silver back to pure shiny silver. After a few cleanings, all the silver was gone. I would hate to have us remove some essential ingredient in the carbide or brazing, in the process of removing the gunk.
