Limestone is a sedimentary rock made of carbonate minerals used in construction for thousands of years. It is valued for its beauty, durability and natural properties, making it a popular choice for countertops, floors and walls.
Maintaining limestone can be a real challenge. It is porous and soft, easily damaged and soaks up spills. They must be regularly cleaned and maintained to keep limestone surfaces looking their best.

Next, use a Ph-neutral limestone cleaner with a damp microfiber mop. Avoid being tempted to use a general detergent because it contains chemicals that can damage the limestone or the sealer.
Do not use abrasive materials or stiff scrubbing brushes, as they scratch the stone's surface.
Also, avoid using acidic cleaners, such as vinegar or lemon juice, as these will etch the limestone.
If you have a stubborn stain, use a poultice made of a mixture of talcum powder or diatomaceous earth and a cleaning solution. Put the poultice on the mark and cover it with plastic to stop the cleaner from evaporating. Leave the poultice on the stain for 24 hours, then rinse with clean water. For more difficult stains, you need to use a professional cleaning service.
Super-heated steam can degrade the sealer and create micro-fissures on the stone's surface. In extreme cases, steaming can result in the 'spalling' or flaking of the limestone.
