I cleaned this driveway a few days ago for someone, and a couple days later they decided to give me a call back and say that the driveway still had dirty spots. I couldn't imagine what he could be talking about, because the driveway was not extremely terrible to start with. I down streamed undiluted SH and roof snot before I started, and I washed it twice. First I washed it horizontally, and then I went back over it quickly washing vertically to cover any missed striping. After I was done I sprayed it with the SH again. These photos are what I saw when I came back. I think he thinks it's still dirty, but it looks like it's just discoloration in the concrete. Maybe its due to the fact that the last guy to wash it before me etched the concrete. He admitted to knowing that the last guy etched it before I ever left the first time. I tried to hit it again, but nothing is changing. I'm pretty sure its not dirty. What should I tell the guy?
