This high-quality, durable utensil made of stainless steel effortlessly cleans cast iron, wrought iron and stainless steel without damaging the valuable patina. The cookware should cool down, then with some warm water one can gently scrub off the burnt residue. No dish detergent is needed. After cleaning the cookware should be rinsed once more and then dried thoroughly before stowage – otherwise contact corrosion is possible
