How Does It Work?
Concrete and bluestone floors are notoriously porous and if oil from cars or fat from food and chips is spilled on these surfaces, an ugly dark stain is produced. It can also occur when hydraulic hoses break in machinery such as scissor lifts. Because the oil soaks down into the surface, cleaning these spots with a heavy-duty detergent is not effective. The surfaceoil will be removed, but the oil that has soaked in will still be there deep in the pores, and it will migrate to the surface to fill the place of the oil that has been taken away. So, the spots will come back! This is very frustrating for the cleaning staff. To overcome this problem, we developed OIL REMOVAL PASTE. This paste is spread on the stain and left overnight to activate. The turpentine in the paste wets the area and dissolves the oil. As the turpentine evaporates from the top of the patch, the oil is carried up into the powder component of the PASTE. Next day, the paste will have dried to a powder, which is swept up. The oil spots are removed by this process, which is called the poultice method.
