6 Pieces Chore Boy 100% Pure Copper Rust Free Scrubbers, for Pot and Pans

These scrubbers are 99.997% pure copper. Mineral oil is used to draw, spool, and unspool the copper wire. In addition, it helps to make the manufacturing process easier and protects the wire from scratches during use. Chore Boy Copper Scouring Pads do not have any type of overlay coating on the finished product. However, we do use a wire drawing process that pulls the product through an oil-based lubricant for manufacturing purposes. Most of this solution will dissipate or evaporate with exposure and the rest will wear off over time.
