This sidewalk at a cabin on Mille Lacs is continually in the shade and therefore tends to have moss, creating a slippery surface. The owners had tried scraping and spraying with a hose, but could not get rid of the problem. They finally decided to try a pressure washer. They were amazed with the results. The pressure washer was fast and efficient in cleaning off the moss. You can see for yourself in this photo what a difference cleaning with a pressure washer makes. Hotsy, what the pros use!
