Cultured marble products are manufactured with natural stone dust and a high-gloss gel coat that becomes an integral part of the material. Colorants are used to create the “veining” that simulates the look of natural marble, according to the International Cast Polymer Alliance website. It can be tinted to create a wide range of color choices. The resulting product is a durable, molded surface that does not have the porosity problems of natural stone.
Cultured marble provides a tough surface for bathroom and kitchen areas. Cultured marble resists staining. When troublesome stains do occur, cultured marble surfaces can be restored with a number of products available through the manufacturer. Avoid the use of abrasive cleaners that will create scratches in the surface material. Squeegee the cultured marble after water use to remove spots. Dried spots can be removed with vinegar that's been sprayed on and allowed to sit for 45 minutes to an hour. Then wipe with a soft cloth. The manufacturer of your cultured marble surface may offer special cleaners that are safe to use on your material.
Scorch marks can occur in cultured marble surfaces from cigarettes, curling irons or hot pots and pans. Always use a trivet or other protection under hot cookware. Use a heat-proof tray under curling irons and other heated appliances. Scorch marks are difficult to remove from cultured marble and may require the services of a professional cultured stone contractor to affect an acceptable repair.
Very light scorch marks may be buffed out with a buffing wheel. Though abrasive products are generally not recommended on cultured stone, they can be used to remove burn marks from the surface. The damaged area is then covered with a gel gloss polish to smooth and shine the surface, according the CountertopSpecialty website. More serious scorch marks will require removing the damage and restoring the resin finish with a patching compound. Repair solutions for cultured marble are generally available through your manufacturer. Other products are on the market but may not provide a good match with the color of your material.
