I am looking to be cleaning some concrete parking lots. Was wondering if anyone had any good ideas to clean the oil off the concrete and remove the the staining without hurting the concrete. I am not sure what is the best way to go about this.
Like Dan said, hot water and a good degreaser. EnviroSpec has a product that I have had great success with. It is their Power Stroke concrete cleaner. I ordered one drum kit, and was impressed.
