Oxidized silver is produced when oxygen reacts with silver. The oxidized silver is darker and its finish lacks shine and sparkle. There are different methods used to clean oxidized silver. If you are eco-conscious, you will use an eco-friendly cleaning method. If you care less about the environment and toxic chemicals, you can use steel wool, a polishing pad, and silver polish.
The Eco-Method For Cleaning Oxidized Silver
Step 1 - Put Baking Soda in Foil and Water
Add about one tablespoon of baking soda and a piece of foil about four-inch square (approximately) to a pot filled with water. Submerge your oxidized silver in the water. Boil this mixture until the silver starts to look bright and shiny again.
Step 2 - Cool Silver
With a pair of tongs remove your piece of silver metal/jewelry and place on a clean dry towel or microfiber cloth.
Using Silver Polish
Purchase silver polish in the store. Take a small portion of the silver polish (usually no more than a dime-size) and using a polishing pad or a scouring pad, clean the exterior of your oxidized silver until it shines bright. Re-apply additional silver polish to your oxidized silver until you are satisfied with the color and brilliance.
