Dirt, dust, and pollens are more prevalent outdoors. This, combined with the fact that these stairs are limestone, a porous natural stone, caused algae to grow. At BiO Tile and Grout Restoration, we use a hot water and extraction cleaning method, including special hand-held equipment, to completely clean even in tight quarters like you see on these stairs.
