Ultrasonic Cleaner for Parts and Towels

I’m looking for a cleaning solution to use in our industrial ultrasonic cleaner that is similar to the old style competitor detergent. We use it occasionally for general cleaning, removal of machining oils, cleaning for high vacuum use, and to lightly etch the oxides off of copper.

Could we also use this mix for washing microfiber towels and foam sponges that have various waxes, polymer sealants and oils on them?
