Using the Fomos Sink is a breeze. Just place your dishes, utensils, or whatever you need to wash right in the single bowl. For day - to - day use, you can clean it with a mild dish soap and a soft sponge. Avoid using abrasive cleaners or scouring pads as they can scratch the granite surface. When it comes to maintenance, dry the sink after each use to prevent water spots. Also, don't leave acidic substances like lemon juice or vinegar in the sink for too long as they can damage the finish. If you notice any stains, try using a non - abrasive granite cleaner. That's all you need to know to keep your Fomos Sink in top shape.
