Granite is the perfect choice in sinks when looking for durable and easy-to-maintain beauty. This natural stone is resistant to heat, chipping, fading and staining. Composite black sinks are comprised of highly compressed granite particles. The price generally runs high for these sinks due to their long-wearing nature, so correct cleaning methods are an important part of protecting your investment. Using abrasive cleaners and scratchers is a no-no. Wearing away the top protective layer will leave a rough surface. Mild detergent and water will complete this 15-minute clean.
