Marble countertops are slightly porous and more susceptible to staining compared to some other materials like granite or quartz. However, cleaning spills off marble countertops is not particularly difficult if you act promptly. Wipe up any spills immediately using a soft cloth or paper towel to prevent stains from penetrating the surface. For a more thorough cleaning, use a gentle, pH-neutral cleaner specifically designed for marble, or a solution of mild dish soap and water. Avoid using abrasive or acidic cleaners, as they may etch or damage the marble surface. Regular sealing can also help protect your marble countertops from staining and make cleaning spills easier.
