The Aged Brass finish has been designed to look beautifully antiqued upon installation and has been left unlacquered to patina over time. If cleaning is necessary, it should be done with a soft cloth. The real beauty of this finish lies in the mellow, aged look of the brass, as though it has been an original part of the interior for many years. The toggles, dimmer knobs and push buttons are supplied polished but unlacquered, which will also mellow with age.
