Softwashing is the safe alternative to pressure washing. We use water based, biodegradable chemicals. They emulsify dirt and grime, break down bug nests and spiderwebs as well as kill mildew, algae and bacteria while sanitizing the surface we are cleaning. Soft washing uses only one third the water of pressure washing, lasts four to six times longer and doesn't erode the surface, like a pressure washer often can.
