Tin cookie cutters are hand molded from tinplate, the industry standard of quality for years. Avoid having the tin cookie cutters come into contact with anything acidic, as the tinplate can wear off.
Tin cookie cutters should be gently washed by hand (avoiding the use of anything abrasive). Never put them in the dishwasher. Moisture is the enemy of tin cookie cutters.
They should be dried quickly, and thoroughly to prevent oxidation. If you live in a humid area, it is suggested that the tin cookie cutters be dried in a warm oven (oven should be heated to a low temperature and then turned off before putting cookie cutters in), for 2-3 minutes.
Tin cookie cutters can be easily bent, so store them carefully. Store your tin cookie cutters in a cool and dry location. They can be stored loosely in containers, bins or drawers. Be careful when sorting through them or putting them away as not to force them, as this can result in bending.
