Cultured marble, cultured granite, and Granite Fusion require the same care and cleaning.
Any normal bathroom cleaner such as Scrubbing Bubbles, 409, or Lysol should work just fine. You do not want to use Comet, Ajax, or Soft Scrub. Anything abrasive will scratch your marble's surface. Also, nail polish, polish remover or paint remover will cause permanent damage.
Natural Granite Care and Maintenance
Your granite is sealed by the installer once the job is complete. You are required to re-seal your granite once a year, to protect it from staining and keep it looking new.
You can wash down your contertops with a mild dishwashing soap and warm water, or a stone cleaner. Don't use to much soap, this may cause streaking.
Do not use any cleaning products that have lemon, vinegar, or anything with a high acid content. This may etch or harm the finished surface of your granite.
You always want to blot up spills immediately. Especially for red beverages and oily products, such as butter or vegetable oil.
