Care & Maintenance Guide

General Care Instructions

  • Gloss Finish: The beauty of cultured marble and molded marble surfaces is the ease of cleaning and maintaining the new shiny look. The best way to clean cultured marble is to wipe with a soft cloth or sponge using a mild soap and water or a non-abrasive foam cleaner. To maintain your marble/granite luster, periodically apply a protective coat of wax. We recommend GelGloss™. It is like a furniture polish that should be applied every few months, depending on use. Boat or car wax is also a good means of protection.


    Matte Finish: Use a soft sponge or cloth along with mild soap and water when cleaning cultured marble surfaces. If desired you may use a very mild abrasive cleaner for this type of finish. (Scotchbrite) You may also put a protective coat of wax with GelGloss™ on this type of finish.

    Tip: Regular cleaning prevents buildup and keeps your surface looking new.

  • Cultured marble is durable, but like any surface, it can scratch if exposed to sharp or abrasive objects.


    All bathroom fixtures, including cultured marble shower walls and molded marble products, will scratch if they are purposely abused. Normal care and cleaning of cultured marble/granite products will ensure years of enjoyment and use. Avoid placing sharp abrasive objects on the surface; they will scratch.

  • Gloss Finish: Yes. Fine scratches on cultured marble surfaces can be removed with automotive paint buffing compound and a handheld polisher. A company technician should take care of deeper scratches.

    Matte Finish: This finish on molded marble will not show minor scratches. However Scotchbrite can help resolve basic scratching.

  • Cultured marble/granite is very rugged with a hard waterproof, stain-proof surface. If it should scratch or chip, repairs can be made by a company technician.

    Sometimes all that is needed is sanding and polishing. Other times the chip must be filled with the same material it was originally made with.

    Both of these procedures require a person with the knowledge and tools needed.

  • Cultured marble/granite is thoroughly tested to resist stains from ink, hair dye, shoe polish, iodine, crayons, bleach, drain cleaners, ammonia, hydrogen peroxide, and many other products commonly found in bathrooms, including cultured marble shower walls.

  • Gloss Finish: Simply rinse the area with soap and water and wipe clean. This is the best way to clean cultured marble shower surfaces after spills.

    Matte Finish: Rinse with soap and water and wipe the area clean. If the stain is still visible apply an abrasive cleaner (Ajax or Soft Scrub) and rub out or use a Scotch Pad with a light rubbing motion until the stain is removed. This method is also effective for cleaning cultured marble shower walls.
