This concrete floor had suffered from an oil spill that was further worked into the painted surface by a forklift truck over a period of time. The warehouse is used to cut new carpet, so we had to remove all of the contaminant to insure the carpets stayed clean while they were being prepared for installation.
The owners had tried several times to remove the soiling with mops and brushes.
Fortunately we were able to lift all of the oil spill & soiling, using just enough pressure and agitation not to damage the working surface. Handing back the warehouse for use later that day.
