Hot on the heels of our last post, here is another citation from the Energy Citations Database at the DOE’s Office of Scientific & Technical Information (OSTI).
In a DOE funded project, at the Oak Ridge Y-12 Plant, they replaced vapor degreasers and chlorinated solvents with ultrasonic cleaners and aqueous detergents. The impact was significant. Previously parts were soaked overnight to remove baked-on varnish. In extreme cases, additional wire brushing was needed to remove stubborn contaminants. The ultrasonic cleaning though eliminated all that! Parts cleaning took about 20 minutes and that too with no pre-soaking or wire brushing.
Calculate the cost impact of 20 minutes versus overnight soaking and wire brushing. No wonder we go a bit overboard about ultrasonic cleaning!
