Need the recipe for cleaning silverplate.

I sell a lot of silver on Ebay. Jewelry, silverware, serving sets. Silver polish and dips tend to remove some of the metal. The foil method doesn't work that great and still leaves a grey film that still needs to be removed. I use white toothpaste (not gel)and a damp toothbrush. For large items I use a damp cloth. Also works on copper, brass, gold, porcelain, ceramics, sneakers, plastics, etc. For my sales I needed one product for cleaning everything.

This will work. I have done it with my rings.

That will work for jewelry, but these a larger pieces. I need the formula that includes aluminum

foil and baking soda and/or salt and boiling water.
