Durable and less expensive than natural granite, granite composite sinks are made of pressed granite stone dust and acrylic resins. In no time, a granite composite sink can look dull and streaked, so it's important to know how to clean one properly. Refrain from using full-strength bleach or cleansers with ammonia on your granite composite sink. Avoid chemical drain openers, and stick with "soft" cleaning instruments; harsh chemicals, steel wool, and abrasive sponges and brushes can do lasting damage.

Step 1

Clean your granite composite sink daily with soapy water and a sponge or a soft nylon brush. Rinse the sink, then dry it thoroughly to prevent water spots, soap and mineral deposits from clouding the finish.

Step 2

Remove tough stains from a granite composite sink by reaching for your choice of some common household products. Spray the stains with a 50-50 mix of white vinegar and water or apply a paste made with baking soda and a little water to the stains. Rinse the sink and then wipe it dry.

Step 3

Mix a 50-50 solution of bleach and water and apply it to the most stubborn sink stains. Drench the sink with water after cleaning it. Then wipe it dry.
