How to Clean Granite Monuments

Granite monuments are quite popular due to the beauty of the natural material, as well as the durability. A granite monument will last for many years. Although this material is long-lasting, it can become dirty and dingy over time if not properly cared for. It is important to clean a granite monument regularly to keep it from discoloring.
