Limestone is a porous, soft, and chemically sensitive stone than marble or granite. Acids and acidic solutions can etch them. As a result, regular attention to care and maintenance is essential for preserving the appearance of your limestone countertop for a long time.
Limestone is a natural stone that has a porous surface. This means that it can easily become stained from acidic fluids. To protect your limestone countertops from staining, you will need to apply a sealer to the surface on a regular basis.
The pores are filled and spills on the surface are repelled when you seal. When cleaning your limestone countertop, avoid using acids-based cleaners. Furthermore, acidic foods and hot items should not be placed directly on the countertop surface.
Because the limestones are so soft, you should be cautious not to use your knives on a surface that isn't protected by cutting boards
