Cleaning Produce Washing Equipment: Brush Washer Conveyor System Checklist
Robert Hadad, Extension Vegetable Specialist
Cornell Vegetable Program
As we learn more about reducing microbial risk on the produce farm, more emphasis is being placed on cleaning food contact surfaces. Accessing the hard to reach spaces in wash line equipment is challenging. Most of the equipment was not made to come apart very easily or in an economically efficient manner. The checklist provided here has been developed through hands-on research cleaning equipment as thoroughly as can be measured without doing microbial testing. That level of cleaning is still being researched but, from our work, the level of cleanliness provided here appears to be sufficient.
This step-by-step checklist provides visual guidelines and suggestions for reasonably cleaning your equipment.

The presentations found below provide more photos of the steps of cleaning the conveyor, the brush washer, and the absorber.
