How to Remove Hard Water Stains From Composite Granite

Updated April 17, 2017

Granite is a durable and attractive stone, making it a popular choice for kitchen and bathroom countertops and sinks. Composite granite, made from compressed acrylic resin and granite particles, is commonly used for countertops and sinks because it's less expensive than solid granite. All forms of granite need careful cleaning and maintenance to keep them looking smart and shiny. Removing hard water stains and scale from composite granite countertops is a simple job that takes only a few minutes.

  1. Fill a bowl with hot water and a squeeze of dish detergent. Dip a soft, clean cloth into the water and wipe over the composite granite surface to remove all dirt, crumbs and food remnants.

  2. Pour white vinegar into a bowl to a depth of 1 to 2 inches.

  3. Soak a clean cloth or paper towel in the white vinegar for about 1 minute.

  4. Place the cloth or paper towel over the hard water stain or scale deposit. Spread the cloth or towel out flat. Leave it in place for 30 minutes and remove it when the time expires.

  5. Rinse the affected area with a cloth dampened with clean water. Blot the area dry with a paper towel or dry cloth.

  6. Tip

    Treat your composite granite countertop with a granite sealer and non-abrasive polish to maintain its shine and protect it from stains.


    Never use acidic cleaners, ammonia or abrasive pads to clean or remove stains from composite granite. All can damage the surface.
