Using a car battery charger, salt water, cotton swab, and a custom designed and vinyl cut stencil, I was able to remove the silver platting on a Zippo lighter shell, revealing the brass colored metal underneath. Connecting the positive terminal to the lighter, and removing the silver platting with a salt water soaked cotton swab connected to the negative terminal. After the plating was removed the corrosion needed to be polished off to reveal the shinny custom Zippo.
