Crete Eater uniquely attacks concrete, cement, stucco, mortar, and grout by softening the build-up into a mud. This formulation is designed to remove concrete from ready mix trucks, pump trucks, equipment, concrete saws, pavers, molds, curb machines, tools, tankers, and forms. It cleans with the power of an acid but is mild enough for hand washing of equipment with little or no skin irritation. Dilution ratio of 1:1 up to 7:1.
