Power Wash

It's been almost a year since I power washed the concrete so today was the day.  The dirt and mildew gets down deep in the concrete so it's more than a quick rinse to get it off.  You have to hold it down close and do about a two inch strip at a time.  Bottom line is that it took all afternoon to do the front drive.  The back is great since I put the concrete coating down a few months ago.  It only takes a quick rinse to get it clean.
