The RIEDEL Bottle Cleaner is a practical and effective accessory from the RIEDEL brand. These small stainless steel balls remove dirt, residue, sediment and surface stains from the inside of your carafe. Fill the decanter with water, add the marbles and swirl around. When cleaning is complete, carefully empty the contents into a strainer, rinse the balls and let them dry. If dried and stored properly, the balls can be used many times.
