Limestone is found to be a natural calcium carbonate which, like marble, you will find is sensitive to acid solutions. The surface itself is very smooth, and it comes in various hardness, which some of the more dense can be polished. Though you will find that it can be polished, it may never be as shiny as marble or granite. Due to what the stone is made out of, it is very absorbent, and many different liquids can stain or start deteriorating the stone itself.
The basic care for limestone flooring would require frequent cleaning with a dust mop that is dry and non-treated. A variety of debris can cause damage to limestone, the worse being sand, dirt, and grit due to them being the most abrasive. Though you can use a vacuum to help remove the debris, it may be best to either use the dry dust mop or a vacuum that does not have any metal or worn plastic attachments as they can cause scratches and damages to the surface as well.
The next step would be to use a damp mop to apply a ph neutral cleaning solution to thoroughly clean the surface, and then rinsing it multiple times to make sure the solution has been removed along with any soil or dirt. Once you have rinsed, it is important to make sure to dry the flooring, usually with a microfiber cloth. Keep in mind that this process can be done yourself to remove both dirt and stains, but many stains may need a professional to help remove without further damage being done.
There is a restoration and polishing process that can be done next if the surface of the limestone is heavily scratched and dull. Using a variety of special polishing pads specifically for limestone helps sand down the surfaces to the point where it not only takes out any scratches or blemishes, but it also brings out the shine again. Usually this needs to be done every year to couple years depending on how much traffic comes through your home. Over time it is possible for your limestone to become chipped or uneven. This can also be taken care of with the polishing process.
The final process would be to seal the limestone. This last step helps prevent any deterioration within the stone. Applying a sealant, especially one that is a penetrating sealant will seep into the pores to better protect the stone. This will help protect the stone from everyday spills, making it bead on the surface instead of seeping into the stone. This process usually needs to be completed every year or two. Though this step will protect the limestone from a liquid to seep into the pores, it still will not protect it from any etching from any type of acidic liquids.
