Granite & marble countertops are not more difficult to clean & maintain than other surfaces. A gentle, ph-neutral antibacterial cleaner is recommended, with soap and water being an effective cleaning agent. Clean your countertops with warm water and a few drops of liquid dish soap. Rinse thoroughly, and dry with a microfiber cloth.
Never use harsh chemicals or abrasive cleaners, such as ammonia, bleach, vinegar, or citrus-based products.
Properly sealed stone will repel most stains. Always promptly wipe up any spills to prevent staining. The longer the liquid sits on the countertop, the more likely it is that it will seep into the stone and stain your countertops. When you spill something on your countertops, blot with a paper towel or soft cloth immediately. Avoid wiping, as this can spread the spill. Flush the area with soap and warm water and rinse thoroughly.
If you have a stain that is not easily removed, a poultice may be needed. A stone poultice is a fine, non-acid, absorptive cleaning powder that removes deep-set stains. Poultices can be purchased or homemade from common household items.
