How Does This Homemade Silver Cleaner Work?
+++
My son and I need to do a science experiment for his Cub Scouts. We want to do "chemistry around the home." I recently saw a home remedy silver cleaner made with table salt, Calgon water softener, aluminum foil and hot water. It worked great on some badly tarnished silver. Can anyone explain why this works, and what part each of the three main ingredients play in making it work?

The chemistry is explained pretty well near the top of letter 4785. Good luck with the project.

Thanks so much! My mom just brought this trick back from Canada, and it works so well, my son is also using it as a science fair project, and we needed to know why it works.
looked at the letter, saw you use
baking soda [linked by editor to product info at Amazon], we used calgon water softener, I guess it is the same chemical, I haven't looked. would the chemical formula be different? ......again thanks

The chemical reaction is between the silver and the aluminum, and it is the same regardless of whether you use baking soda, washing soda, water softener, or Spic 'n Span as the conductivity salt. Some say some of these work better, and certainly some are harsher. If baking soda works for you, it's probably the mildest on your hands.

I have heard that baking soda, ammonia and boiling water will clean silverware. Is this true, is it safe and if so, what amounts would one use.

What is the recipe for silver cleaner...how much of each thing? I know you line the pan with foil but how much salt, water softener to boiling water?

Hi, Barbara. It really doesn't matter. The reaction is between the silver and the aluminum. 1 cup per gallon is probably as good a number as any. The salt or water softener or Spic 'n Span [linked by editor to product info at Amazon] or baking soda or washing soda is only there to make the water conductive. letter 4785 goes on almost endlessly about this subject :-)
