After use of metal utensils, gray marks may become noticeable on the surface of tableware. These are called metal marks and they are caused by the friction between the porcelain and metal.
If the porcelain products have a glossy glaze, these marks are not easily noticeable. In light color or matte glaze products, they may become more apparent.
The metal marks can be removed. We recommend using a soft cleanser, such as Bar Keeper's Friend and gently rubbing with a wet cloth or sponge.
