To clean your sink, use a soft cloth, sponge or soapy nylon brush. Be sure to rinse the sink well after cleaning and dry. Cleaning on a regular basis will help prevent the development of hard water deposits. If you develop persistent stains, try a non-abrasive cleaner such as dishwasher soap, Soft Scrub or a professional stone cleaner solution which can be purchased from a local hardware or tile store. DO NOT use any acidic tub and tile cleaners, toilet bowl cleaners, ammonia, abrasive or soft paste cleaners, vinegar, alcohol, window cleaners or lemon juice. In addition DO NOT use abrasive cleaning pads such as steel wool, metal brushes or scouring powders. Custom duties and taxes MAY be added for deliveries to outside European Union.
