The look of the brass will change with time. Cleaning all surfaces with a mild soap, water, and a non-abrasive cloth will help the hardware age gracefully.
Water conditions vary across the country. Chemicals and minerals in the water and air can combine to have an adverse effect on the finish of hardware products. We recommend that you rinse away any traces of soap and gently dry with a clean, soft cloth after each use.
Do not allow materials such as toothpaste, nail polish remover, or caustic drain cleaners to remain on the surface.
