Before using your cutlery for the first time thoroughly hand wash in warm water and mild soap and hand dry. This is to remove any leftover residue of oxidized finish and vegetable oil from the manufacturing process. While your cutlery is dishwasher safe, we recommend care similar to that of plated cutlery. 1.Hand wash in warm water with mild soap or detergent. 2.Towel dry. Because of the unique oxidized finish of these hand forged pieces unusual spotting (oxidization) may occur if left unattended in the dishwasher cutlery rack. Should spotting occur we recommend wiping the handles with any household vegetable oil.
