Proper maintenance is essential to keep granite countertops looking their best. Granite is a porous material, so it requires periodic sealing to prevent stains and moisture absorption. It is recommended to reseal granite countertops every one to three years, depending on usage. Regular cleaning with mild soap and water is usually sufficient for day-to-day maintenance. Avoid using abrasive cleaners or scrub brushes that can scratch the surface. While granite is heat-resistant, it is still advisable to use trivets or hot pads to protect the surface from extreme heat. With proper care and maintenance, granite countertops can retain their beauty and durability for a lifetime.
