You should call KYZEN Regional Manager, we will be there to help as much as we can. You don’t want the wash bath to get to the point where you’re no longer able to clean parts so the idea is to develop a process and method when its almost too soil loaded and that’s when you want to change it. We would like to have the process for you run as long as it can as well as it can and use as least as it can that’s really what we’re all about.
