Many staining conditions are created by excessive moisture in the walls. To avoid this, protect open wall cavities from rainwater during construction and correct any structural problems that allow water to enter the walls.

Used properly, Heavy Duty Restoration Cleaner dissolves heavy carbon and many other stains commonly found on masonry buildings in highly polluted areas. Dilute with water to produce a cost-effective, general-purpose restoration cleaner for brick, granite, sandstone, slate, terra cotta and many other masonry surfaces.
