The Petromax chainmail stainless steel scrubber is ideal for cleaning cast or wrought iron cookware after cooking over an open fire. You can effortlessly clean your  pan or  skillet  without damaging the valuable patina. The structure of the intertwined rings gently removes food residues without scratching the cookware’s surface.
 
How to: Cleaning without dish detergent
Let the cookware cool down, possibly let it briefly soak, and scrub off the burnt residues with warm water and the chain mail cleaner. You do not need any dish detergent. Rinse the cookware again thoroughly after cleaning. Before putting your cast- or wrought-iron cookware back into the cupboard, always dry it well and treat it as usual. The chain mail cleaner should also be left to dry thoroughly after use.
