Soft washing is a low pressure cleaning process commonly used to safely treat and remove organic matter: mildew, bacteria, algae, fungus, moss, lichens in addition to dirt, grime and spiderwebs. Soft washing originated as an alternative to power washing where high pressure can cause damages. The application is achieved from low pressure dedicated pumps where measurements of commonly used products, mainly sodium hypochlorite (bleach) and detergents can be preciously metered and applied.
Soft Washing continues to evolve. Pumps now available producing more pressure than original electric diaphragm pumps, allowing solution to be safely applied at further distances and adding increased rinsing volume. (Booster pumps, air diaphragm, and gas powered diaphragm pumps. Metering systems, allowing precise metering and mixture of sodium hypochlorite (bleach), detergent and water. Color marking detergents available to show where mixture has been sprayed, reducing usage while assuring proper coverage. Remote systems to switch between applying solution and rinsing. Neutralizing agents to aid in reducing damages that can be caused by chemicals. Soft washing has drastically changed the proficiency and safety of cleaning structures and roofs.
