Chore Boy 2 Pack 3"x3" Copper Scouring Pads are made of pure copper, a natural anti-microbial agent that effectively removes tough dirt and grime from pots, pans, and other surfaces. These durable scouring pads can be reused multiple times and are easily cleaned by rinsing them with water. Unlike steel wool, they won't rust or splinter, making them safe for use on cookware made of stainless steel, copper, anodized aluminum, or multi-clad. They are also ideal for cleaning glassware, barbeque grills, stove burners, oven racks, and other heavy-duty tasks.
