In order to clean your wave ring that does not have any inlays or gems, you can use baking soda. First, you need to make a paste of one part of water and three parts of baking soda and mix it well in a glass bowl. Then, you need to wet your wave ring and apply the paste (on the ring) with a soft microfiber cloth. You need to rub the paste present on the ring in circles through the cloth so as to remove the tarnish. Once done, you can rinse away the paste of baking soda and use a soft towel to pat dry the ring.
