All tin cookie cutters are hand molded from tinplate, the industry standard of quality for years. Tinplate consists of thin sheets of steel, for everlasting durability, coated with tin on each side. Tin cookie cutters will not rust unless deeply scratched to the steel core or unless exposed to moisture.
To ensure a lifetime of use, simply handwash your cutters with warm, soapy water and dry promptly and thoroughly. Always use a soft cloth or sponge. Never use abrasive cleaning materials, metal scouring pads or any detergent that contains alkali or acid. For added protection, you may choose to enhance the drying process by placing your cutters in a slightly warmed oven, turned off, for 2-3 minutes. Also, you may take a hair-dryer on warm or hot setting and dry your cutters to ensure there is no trapped moisture.
Store all metal cookie cutters in a cool and dry place.
