Pressure washing, also known as power washing, is a cleaning method that uses high water pressure to get rid of dirt, moss, and other contaminants off of your concrete, bricks, or pavers. In addition to that GWP soft wash uses a solution that will make your driveway sparkle. We call it a "post treatment" or "pretreatment" when we put our sodium hypochlorite mixed formula on your concrete to make it sparkle when we are completely done with our pressure washing. That is the big difference between GWP soft wash and doing it yourself because if you do all your pressure washing yourself then your driveway won't sparkle like when GWP soft wash does it.
