I bought a lovely hand embroidered kitchen herb themed sampler from a thrift store. There is a water stain on the bottom. The edges, where is was folded to fit into the frame, are soiled. The sampler has the initials BBC 1960 embroidered on the lower right corner. What is the best way to remove the water stain and clean the soiled area. I tested to make sure the embroidery floss is color fast and it is. Thank you for your help.
