Abstract
A hazardous ingredient free cleaning composition and method for cleaning an oil/grease stained concrete surface. The cleaning composition includes (i) about 50 to about 95% by weight of water; (ii) at least about 2% by weight of a detergent builder; (iii) at least about 1% of a surfactant; and (iv) at least about 1% of a coupling agent which minimizes phase separation of the surfactant from the builder during cleaning of the surface. The method includes applying the cleaning composition to the stained surface, allowing the composition to set on the surface, and rinsing the surface with water.
