How do you clean Wedgewood?

Wash the jasper body by carefully using a soft cloth and a mild detergent diluted with warm water. Rinse thoroughly with clean water and dry with a soft cloth. For more difficult marks, gently rubbing with an old tooth brush or soft nail brush with a mild detergent should remove any ingrained old dirt.
