Tin is a soft low-cost metal that covers the steel underneath, and protects it from rust. Hand clean tin cookie cutters with a dishcloth or sponge. Never use abrasive cleaning materials, metal scouring pads or detergents that contain alkali or acid. Tin cutters should be dried with a soft towel immediately after washing to prevent rust from forming on spot welds or around edges where turned or soldered. Store tinned cookie cutters in a dry place. To restore rusted cookie cutters, remove surface rust using fine sandpaper, hand wash with hot sudsy water, dry thoroughly, and lightly coat with mineral oil using a cloth or paper towel. Tender loving care will ensure the longevity of your tin cutter to have them passed down through your families generations.
Happy cookie making!
