Today I was contacted by a contractor who installed 3600 sq ft of honed granite unsealed in a Lexus dealership service facility. From what I was told, the granite has been installed since December of last year and has motor oil staining in several areas of the floor. My questions are, what type of poultice would you all recommend for removing motor oil/ staining and is there a recommended sealer that would be good for this type of stone/ environment! Thanks!
