Commercial silver polish contains toxins, and manufacturers recommend you don’t leave on skin too long. Do you really want something like that spread over your flatware?
Aluminum Foil, Boiling Water, Baking Soda and Salt: Keep your sterling shined with this seemingly magic method. Line your sink or a bucket with aluminum foil, and drop in tarnished silver. Pour in boiling water, a cup of baking soda and a dash of salt. Let sit for a few minutes. The tarnish will transfer from the silver to the foil.
Toothpaste: If you can’t immerse your items or are otherwise inclined to polish by hand, rub tarnished silver with toothpaste and a soft cloth. Rinse with warm water and dry. Instead of toothpaste you can substitute a concoction made of 3 parts baking soda to 1 part water.
Ketchup: To keep your copper pots, pans and accents looking bright and shiny, try rubbing with ketchup.
