3-in. square of aluminum foil
1 tbsp. of salt
1 tbsp. of baking soda
1 cup of warm water
Here's how:
Dissolve the salt and baking soda in the warm water.
Then, submerge the foil and your silverware in the solution.
Let it sit for one hour.
Rinse the silver under the faucet, and then wipe it dry with a cloth.
Or . . .
Rub any tarnished spots on your silverware with a non-gel toothpaste (white paste kind) with a soft cloth, and rinse.
When silver ages, it gains a patina of silver oxide which gives it a certain lustre. DO NOT CLEAN THIS OFF!!!
All that's needed for the most part is to wash in water, and, most importantly, polish it with a clean cloth.
If you leave traces of detergent or salt (perhaps from your fingers), the salt will start to corrode.
