How to Clean a Composite Sink: Tips from Cosmos SurfacesTM


Made from granite stone dust mixed with acrylic resins, granite composite sinks are highly durable, stylish and affordable. But just like any type of sink, composite granite requires regular TLC to keep it clean and gorgeous. In this week’s blog, Cosmos SurfacesTM offers a few helpful pointers for how to clean a composite sink.

How to Clean a Composite Sink Like a Pro

  • Everyday Cleaning – To sanitize and prevent stains, we recommend gently scrubbing your composite sink with a soft nylon brush and soapy water on a daily basis. Once you’ve done so, be sure to rinse the sink thoroughly with regular water and then towel dry to avoid spots on the finish.
  • Deep Cleaning If you start to notice stains or a cloudy finish, it’s time to mix up a gentle solution of equal parts white vinegar and water, or create a paste using baking soda and a few drops of water. Apply the homemade cleaning agent of your choice to your composite sink, focusing on any areas that are stained or dull looking. Then, simply rinse and wipe dry for a revitalized sink!
  • Lifting Stubborn Stains If stains linger after using the above method, try using a stronger solution of equal parts bleach and water. Once again, rinse and dry the sink thoroughly after cleaning. This should take care of even the toughest stains.

While composite sinks are quite resistant to stains and scratches, it’s important to note that they can be damaged by harsh chemicals and abrasive scrubbing devices. Stick to these guidelines for how to clean a composite sink, and you will easily preserve the beauty of your sink while extending its lifespan.
