The emulsifying action of Corotech Oil & Grease Emulsifier lifts oil and grease out of voids, cracks and crevices then converts this oil matter into a soapy solution. It then can be easily rinsed away with clean water. Corotech Oil & Grease Emulsifier should be mixed with water before use, 6 parts water to 1 part emulsifier for heaving cleaning requirements and 15 parts water to 1 part emulsifier for light cleaning. A mixed gallon will clean approximately 100 square feet of area. Pour the water and emulsifier mixture onto the surface to be cleaned. Allow this solution to work for 15 to 30 minutes then scrub the surface with a stiff bristled brush. Rinse thoroughly with clean water or pick up residue with a wet/dry vacuum. Repeat the cleaning procedure if necessary.
