High pressure, high temperature water cleaning sprays are directed through header nozzles onto the strip to thoroughly clean its entire surfaces. Venturi vacuum is utilized whenever desired to draw a cleaning additive into the system where such additive is entrained in the water stream. Simplicity and economy are achieved in a highly efficient cleaning system.
