Guys, I'm out there busting my tail everyday trying to learn this business to be efficient and make a few bucks but I am having a problem. Ive tried all different kind of things on concrete oil stains like Aluminum brightener, straight Simple Green, heavy duty degreaser,high heat with turbo nozzle, some stuff from ***** ???, even some of my carpet cleaning stuff. I need to know what is the absolute BEST thing to use on oil stains that will reduce the stain somewhat. Im tired of fightin with all the chems and not seeing desireable results! Thanks guys! Oh by the way, a competitor was washing a gas station across the street from where I was and they were prespraying the oil spots with something that was in a sureflo sprayer.
