    Abstract: The present invention relates to a galvanization process that comprises a residue cleanup step which aims to provide many improvements and facilities to manufacturers and processors of metal wires in general. The process of this invention removes the use of lead of the conventional wire cleaning process for galvanization and incorporates a step with a stearate removing composition which maximizes the galvanization efficiency and reduces lead acquisition and energy costs to heat said lead, and avoids handling of lead and oxide formed on its surface. Thus, the process of this invention makes the environment less insalubrious and reduces the impact of this activity on the environment.
