Here is a good way to clean your jewelry.
Do this:
Mix a cup of vinegar with a table spoon of baking soda. Then, drop your bracelet, ring, or necklace in. The chemical reaction that is created once the two elements are mixed will dissolve dirt and grime off your jewelry. After the fizzling stops and the bubble have disappeared, take out the jewelry and dry them off. Take a shining cloth and buff them. Your end result will be great, shiny, and clean jewelry.
This is also a great way to save you money from buying expensive jewelry cleaners. Happy cleaning!
