STI SlurrySafe AR is a patented synthetic acid replacement engineered to deliver the cleaning power of traditional hydrochloric (muriatic) acid without the hazards. This biodegradable, non-toxic, acid-free formula instantly dissolves hardened concrete slurry, cured concrete splatter, calcium-based deposits, thin-set, brick mortar, and lime-based patching materials while remaining safe on paint, rubber, Velcro®, skin, pumps, pipes, and most metals. Unlike conventional acids, its patented chemistry reacts only with the calcium found in concrete, making it highly effective without damaging surrounding materials or harming the environment.
Designed for professionals in concrete grinding, polishing, and restoration, STI SlurrySafe AR also serves as a grinding aid, pH reducer, diamond tool cleaner, equipment cleaner, descaler, rust remover, and slurry dissolver. It features a “Triple Zero” hazardous material rating, contains no VOCs, produces no fumes, is 100% biodegradable, EPA Cleangredient® approved, and is non-regulated by the U.S. DOT, making it a safer alternative for demanding job-site cleaning applications.
