Pfaltzgraff began as a house pottery company in the early 1800s, offering dishes and serving pieces in various ceramic materials, like stoneware and earthenware. Black marks occasionally develop on Pfaltzgraff dinnerware when tiny pieces of metal from aluminum or silver utensils become deposited on the hard glazed surface. These dark “scrapes” or lines may seem unsightly, but you can typically remove the marks having an inexpensive, homemade glue.
Wash your affected Pfaltzgraff dinnerware piece under running warm water. This helps remove any tiny dirt or food particles that might thwart your mark-removal efforts.
Pour two to three tablespoons of baking soda into a small mixing bowl. Slowly add water and stir the 2 ingredients together till you get a thick paste.
Dip a clean, damp sponge into the baking soda paste. Apply the glue directly onto the black marks, using light pressure to tighten it into the lines. Allow the glue to sit for three to five minutes.
Rub the paste gently with the sponge in a circular motion until the black marks completely come off the dish. Clean your dinnerware piece as usual and dry it with a clean, soft towel.
