How to Clean Cultured Marble


Judy asked: What is the best way to clean cultured marble? We just had a cultured marble counter installed in the bathroom. What is the best way to maintain it?

Cultured marble is easily damaged and requires proper care and use to keep it looking beautiful. Though the steps are simple, they must be followed or the glossy surface will become scratched and dull. Here are the proper cleaning steps along with some helpful tips.

You Will Need:

  • Marble cleaner
  • Microfiber cloth

Steps to Clean Cultured Marble:

  1. Always keep the marble countertop wet while cleaning.
  2. Spray the cleaner onto the surface of the marble countertop.
  3. Wipe it clean with a soft, damp cloth, such as a microfiber or chamois cloth.

Additional Tips and Advice

  • Never use any harsh cleaners or scrubbers on a marble countertop. They will quickly mar the surface.
  • If no stone cleaner is available, a pH neutral, water-based, all purpose cleaner can be used.
  • Keep the countertop dry to avoid hard water from leaving stains and marks. If hard water stains are found, they can be removed with vinegar.


  1. PLEASE NOTE: The use of vinegar is highly discouraged for marble finishes. I had someone working with me in a very high-end home, with, yes, marble countertops in the bathroom. We use vinegar and water on floors where clients prefer us not to use bleach or other harsh fume chemicals. The vinegar dripped on the countertop as she was cleaning the sink, and it ate through the finish and ruined the countertop. Fortunately, the client was still under warranty for the home, so the contractor came by and refinished the marble top. This could have cost hundreds to be done.

    I have been cleaning houses for eight years now, and the best solution, in my opinion, is mild dish soap and water, and rinse it thoroughly, then dry immediately. Safe; effective; kills germs. You can add a capful of vinegar to approx 16 oz. (2 cups) of water and a few drops of dish soap to increase effectiveness against bacterial and viral contaminates if you so desire. However, remember, dish soap is a great sanitizer alone.

    Hope this benefits some of you! Thanks for reading :)
