This was the first job using the newly built power washing trailer. Considering we used a 3% solution and in light rain on a driveway and sidewalks that haven't been cleaned since they were poured 27 years ago, it performed exceptionally. Should've went a little slower with the surface cleaner and there probably wouldn't have been any lines at all. The post treat should knock them down substantially though.
This driveway hasn't been cleaned since poured 27 years ago. This is the result with 3% pretreatment and while it was raining.
