The garage I worked at was having trouble with the ultrasonic detergents cleaning to the best of the ability we knew other detergents could deliver.  I decided to do some research and find a detergent that could really offer removal of heavier soils from automotive, aircraft, and similar mechanical components.  We needed to make sure it was gently enough on the items it was cleaning, but harsh enough to combat the dirt and grime we were trying to remove.  The company I found offered just that in large quantities.  We have been enjoying amazing results since ordering this product and using it in the garage.
