Fine copper threads remove persistent burned on cooking grime. This set of two handy cloths has been denigned as to not leave scratches on enamel and stoves. The copper fibre also has the added benefit of polishing sinks, pans, ovens, ceramic cook tops, glass and stainless steel basins as it cleans. Do not use on teflon or non-stick surfaces. 100% recyclable. Exclusively imported and distributed by Saison.
