CARING FOR YOUR URBIANA BRASS JEWELLERY: Brass naturally tarnishes over time into an antiqued look giving it a beautiful patina. However if you want to get back the shine of your piece, it is easy to clean and look after. You may use home solutions like lemon juice or toothpaste or a commercial brass metal polish like Brasso.
