Pressure Washing Driveways: Should I pretreat? 

There has always been a bit of confusion when pressure washing concrete (flatwork) if "pre-treatment" should be done, and also whether POST treatment is as good of a treatment. Ray discusses both techniques and shows the speed & quality difference in timing when pretreating a heavily algae infested driveway. The power washing on this driveway was performed faster and with better results when a quick pre-treatment was done.
What is Pretreating? It's applying a cleaning solution (in this case bleach and soap) to the concrete prior to beginning a wash process to assist in killing the biological material we'll be removing when power washing this concrete surface.
