How do I remove tea stains from a Royal Albert cup?

Start with this simple approach. Rinse, then use a paste of baking soda and water applied with a soft cloth or sponge, rubbing lightly on the stained area. Rinse well and dry. A short soak in warm water with a small amount of mild dish soap can help with persistent marks; keep soak times short for pieces with gilt. Skip scratchy scouring pads, which can scratch glaze and damage gold edging. Avoid strong bleach on decorated pieces, since it can affect enamels and gilding. After cleaning, check for crazing, since fine glaze lines can hold stain.
