Concrete surface cleaning composition and method

摘要

A composition and method for cleaning concrete and asphalt surfaces from oil and grease stains includes a combination of various constituents, namely baking soda, calcium carbonate, crushed corn, detergent, fly ash, portland cement and/or kiln dust. Other compositions also include quartz sand, ground corn cobs, microorganisms and coloring agents. The method involves contact of the present formulation with concrete/asphalt surfaces, preferably administered in lines spanning the dimensions of the oil stain to be cleaned. The material is swept over the oil stain with a broom or other suitable device to achieve a relatively uniform application. Water is applied to dampen the formulation, thus activating the detergent in the formulation and to hold down dust during the cleaning operation. The formulation rests on the surface for a sufficient amount of time to permit the detergents and other agents to dissolve and/or otherwise dissipate the oil stain. The formulation is then collected from the oil stain surface resulting in a cleaned surface free of oil and grease stains.
