Forgive me Fernando, but i become highly skeptical whenever anyone starts a sentence with "the only way to..."
I do see from a search of the "zinc-soda" method that you have been informing these forums of this "only" method since 2011. In fact you seem to be the "only" person to have mentioned it over the years on our forums. However, each time all i can find is a mention of the name and no description of the process. Have you personally used this method? If so, can you describe the steps? Thanks!
