Georgia Pressure Washers Report post Posted April 22, 2016 Just wanted to share my cleaning experience today. It went well but I did have to apply a second application of roof mix after I rinsed the first one. There was still a pretty good bit of algae left. I gave it an hour of dwell time and my mix should have been right. Anyone have any advise for me? Thanks Share this post Link to post Share on other sites
