Countertop maintenance is essential for keeping surfaces clean and extending their lifespan. Regularly wipe down countertops with a mild soap solution or a pH-balanced cleaner to remove dirt and stains. Avoid harsh chemicals that can damage the surface, especially for materials like granite or marble. Additionally, it's important to seal porous countertops, such as quartz or wood, to prevent moisture and bacteria buildup. Use cutting boards to protect surfaces from scratches and heat. Always follow the manufacturer's guidelines for specific care instructions to ensure your countertops remain in good condition.
