Your limestone projects are important to you, and you want them to remain as beautiful as the first day they were installed. Whether it is the exterior of a building that needs to be protected from graffiti, or an interior fireplace hearth that needs to be protected from wine stains, there are products available that can meet your specific needs. The easiest way to clean limestone is to use a power washer and bleach and water.and good old elbow grease. Test the bleach and water on a small area before you apply it to the whole area. Once you have it cleaned to your liking you can add a sealant that we sell.
We at Weber Stone Company have been using ChemStop® products for many years and recommend it for limestone care.
