I cleaned my patio today. I wanted to share my results to get your advice and opinions. I am attaching pictures of the concrete dirty, half cleaned, and cleaned.
Observations:
1. Now that the concrete has dried... it really is not completely clean. It is in places but not in others. It might be hard to tell in the pictures. (Ignore the mud prints from my dog!!). I used the xjet to apply concrete cleaner and allowed to dwell for 5 - 10 minutes and then started cleaning. Wondering if I should have brushed the surface?? Does anyone else brush the surface??
2. Why does the concrete have the grey areas? This is the first time it has been cleaned in 8 years (since new). I see other concrete like this as well. For example the concrete around our neighborhood pool looks this way as well. Did I damage the concrete? I don't think I did. Washwater remained clear (no grey color). I also varied the distance of my wand to the concrete to learn the best technique.

Any input would be appreciated.
