Duro-Brush anilox cleaning brushes are designed with tapered, extended life plastic handles that resist the impact of water and pressroom chemicals that would otherwise damage traditional wooden handle brushes. Their bristles, engineered to .003-inch diameter, provide improved agitation of dried ink in cell bottoms. New brushes with stainless steel bristles are recommended for cleaning only ceramic anilox rollers while brushes featuring brass bristles work best on chrome anilox rollers.
