Cleaning Machine Oil with Liquinox

Q. We are cleaning straight machine oil off parts, followed by a Ozonics 203 dip. We have a vapor degreaser but stopped using it due to odors & EPA exhaust concerns. I plan to use Liquinox in a strong concentration to remove the residual oil and Ozonics 203. I plan to use the degreaser as a heated ultrasonic cleaner. What concentration would you recommend? This would be followed by our final u.s. cleaning using 2% Liquinox & dual cascading D.I. water.

A. Use 1% if you are cleaning a relatively small number of parts that you do not want to risk any cross contamination and you want to minimize rinse water usage.  Use 2% if you are trying to get a little longer bath life and a very little extra detergency.  Use 3% or more if you are trying to get absolute maximum bath life at the expense of extra rinsing. If you are limited to dual cascade DI, I would probably not exceed 2% Liquinox unless you want very long dwell times in your dual cascade system.
