| I am interested in trying your product, Masonry Cleaner 3427, to clean heavy soiling and water stains from interior flat concrete walls. The building, the New York Hall of Science in Queens, NY, is constructed of cast-in-place concrete with pre-cast concrete panels with inset cobalt art glass. Is this product safe to use on smooth-surfaced decorative glass? Is this product safe for interior use? |
