If you want to wax your skis like the pros, you need to use the Stage brass brush along with your iron and scraper. Brass bristle brushes prepare the base for a fresh hot waxing by cleaning and clearing old wax and the dirt that builds up in it. The brass also opens up the pores of sintered base material to help bases absorb more wax. The outer ring of white nylon bristles clears away the dirt that the brass bristles clean from the base. Tuning your own skis saves money and ensures fun days on the mountain, do it the right way with the Stage brass brush.
