Product Description
Sure Klean 766 Limestone & Masonry Prewash is a strong, alkaline-based cleaning compound formulated for use with Sure Klean Masonry Afterwash. When used properly, the prewash dissolves and assists in removing heavy carbon encrustations from brick, terra cotta, sandstone, limestone and most other masonry.
Old masonry in high-pollution areas is often blackened by deep-seated carbon and mildew stains.
Many of these stains are impervious to standard acidic-based cleaning compounds. Sure Klean 766 Limestone & Masonry Prewash provides the additional chemical ingredients necessary to clean extremely dirty masonry surfaces.(5 Gallons)
