Keep jewelry out of bathrooms and other humid areas. Do not wear when showering, swimming, or in other humid environments (eg. sauna). Clean with a jewelry cloth. We use many vintage brass elements which develop a patina over time. If you desire a shinier look, we recommend "Barkeeps Friend." It can be brushed on with a toothbrush. Make sure to rinse and dry well. As another option, brass items can be soaked for 3-5 minutes in a solution of: 1/4 vinegar, 1 tsp. dish soap, 1 cup warm water. Rinse, dry well, and enjoy!
