There are several ways of cleaning silver jewelry including one method that makes use of aluminum foil and baking soda, which is ideal for small jewelry pieces such as earrings and those with intricate designs. In some cases, silver jewelry, especially those that are just beginning to discolor, may be cleaned with just water and dish soap.
Silver will tarnish over time, and depending on environmental factors, the process may develop quickly or take quite a while.
For jewelry items that are just starting to discolor, mix dish soap with warm water. Dip a soft cloth in the water solution and rub it on the jewelry. Rinse and buff to dry. Toothpaste can also be applied to jewelry and then brushed with an old toothbrush. Rinse and buff dry.
Another method is to mix 1 liter of water with 1 teaspoon of baking soda and a piece of aluminum foil. Bring it to a boil. Drop the jewelry item or items into the boiling mixture for about 10 seconds or longer and then take it out. The jewelry should come out clean.
For heavily tarnished items, mix 1/4 cup baking soda with 2 tablespoons water to make a thick paste. Use the paste to clean the item. Rinse and buff dry. Liquid silver cleaner also works. Apply cleaner on cloth and use it wipe the jewelry item clean.
