Chore Boy ultimate copper scrubbers are created with pure copper using the latest machine knit procedures. These sponges can quickly and effectively remove burnt and baked on food or grease. Steel wool can rust and splinter, causing even more aggravation when trying to clean dirty cookware. Ultimate copper scrubbers don't rust and remain strong until the last scrub. These copper scouring pads are ideal for cleaning cookware made of stainless steel, copper, anodized aluminum or multi-clad. They are also great for glassware, barbeque grills, stove burners, oven racks and other heavy-duty cleaning applications. There's no excuse not to grill outside when clean-up is a breeze.
