We love these little Copper Scrubbers! Fine copper threads clean stuck on food, grease, and grime.  These durable little pot scrubbers are gentle enough to use on most cookware,glass,enamel, stoves, and sinks without scratching. High-quality and long-lasting, these copper pot scrubbers are great for everything from polishing rust off that amazing silverware you found at a yardsale to releasing cooked-on food from your pots, pans and stovetop. The 100% recyclable copper threads are earth-friendly and clean up easily in the washing machine. Do not use on nonstick surfaces.
