Here in Moon & Milk we love oxidized sterling silver because it gives a vintage look to your bohemian wedding or to that awesome summer music festival. But unlike high-polished silver (the very shinny type), you can't use an anti-tarnish solution to clean your oxidized silver because it will wash off the oxidation process, the "vintage look." Use a simple silver polishing cloth to remove dirt without stripping the oxidization. They're are super economical, you can find them at your nearest convenience store for less than ten dollars and it will make your silver look brand new.
