One of the most reliable methods uses salt, baking soda, dish soap, aluminum foil, and hot water. Together, these items create a gentle cleaning solution that removes tarnish without harsh chemicals or abrasive scrubbing. The process relies on a basic chemical reaction that transfers oxidation away from the metal’s surface. When salt and baking soda dissolve in hot water, they form an electrolytic solution. When this solution comes into contact with aluminum foil, it encourages tarnish to move from the jewelry onto the foil, leaving the metal clean and bright. A few drops of dish soap help break down oils, residue, and everyday grime, ensuring the jewelry emerges not only shiny but also thoroughly clean.
