To ensure the longevity of our flatware, we recommend washing by hand (but please do not pre-soak). If you have hard water (water with a high mineral content) we do not recommend using a dishwasher, as elements in the water may cause tarnishing or pitting of your pewter. If not, we recommend cleaning using a liquid dishwasher soap, on the lowest heat setting, for both the washing and drying cycles. Please allow your dinnerware to cool before handling.
