The invention includes a calibrator washer apparatus and a method for cleani ng extrusion calibrators such as a calibrator used in the extrusion of a hollow , thin walled polyvinyl profile for use in the fenestration industry. The inventive calibrator cleaning method involves scrubbing the interior calibration surface of the calibrator with a bristle brush, pumping a hot water and detergent cleaning fluid through the calibrat or vacuum ports that connect to the vacuum slots in the interior calibration surface, pumping hot water through calibrator vacuum ports that connect to the vacuum slots in th e interior calibration surface to rinse off the detergent. The method may further inclu de running cool water through the calibrator vacuum ports to cool the calibrator and wiping down the cleaned calibrator with a water-displacing lubricant. The inventive calibrator washer includes a cleaning fluid tank containing a cleaning fluid, a rinse fluid tank containing a rinse fluid, a main washer tank which is consecutively supplied with and contains the wash fluid and then is supplied with and contains the rinse fluid, at least one main pump that consecutively pumps th e cleaning fluid and then the rinse fluid from the main washer tank through a calibrato r and back into main washer tank, and a transfer pump toconsecutively empty the main washer tank of the cleaning fluid and return the cleaning fluid to the cleaning fluid ta nk and to empty the main washer tank of the rinse fluid and return it to the rinse fluid tan k.
