Over time, your brass jewelry will darken into a beautiful patina. Exposure to oxygen, water, chemicals, and natural body oils contribute to this process. To slow the patina process, avoid keeping your jewelry in the bathroom and remove before bathing or swimming. Keep your jewelry clean and dry, and store in an airtight container such as a zip lock bag when not in use. Occasionally clean with soap and water, and apply lotions and other oils or creams before putting your jewelry on.
To return the metal back to its original tone, wipe with a jewelry cleaning cloth. However, do not rub oxidized (black) silver with a jewelry cleaning cloth, because it will remove the oxidation and return the sterling silver to its natural white color. For stubborn patina on brass, you may try gently scrubbing the piece with a soft toothbrush and a small mixture of baking soda, water, and lemon juice. Rinse with water thoroughly afterwards and dry well.
