Used a pressure washer on the driveway. When done there are lines circling on top of the concrete drive. I went out and went over one square, to see if washing every inch of the surface would help to remove the lines. Any suggestions?

The lines should go away when it dries... if not send me a picture of the lines after the concrete is dry for a day.

We can go from there as long as you rate my ongoing advice positively, I hold the question open without any time limit.

I went out after the section of the drive dried out, and it does work, but it takes time, patience, water, and gas. That seems to work. Next ime I will just use the hose.
