Washown (also wash down) is the process of high-pressure cleaning with water and/or chemicals in industries such as food and beverage and pharmaceuticals. A washdown is usually a manual operation and is designed to kill bacteria and other micro-organisms. Automatic cleaning of industrial equipment is often carried out by clean-in-place (CIP) and/or steam-in-place (SIP) operations. CIP systems often make use of programmable controllers and SCADA software.
