Trial #3
Five sets of 26-28 titanium parts were provided pre-contaminated with J2. Cleaners were heated to vendor recommended temperatures before immersing the parts into an ultrasonic tank for 15 minutes. Visual observations were recorded overall with notes and a set of three parts per cleaner were evaluated by three lab technicians, labelled A-C in Table 1, for cleaner and contaminant residue according using the rating key below.

Visual Observations:
Dowanol PnBGE - Slight cleaner residue and soil residue that remained on parts after cleaning.
Ozzy Juice SW3 - Slight cleaner residue and soil residue that remained on parts after cleaning.
Metalnox M6386 - No cleaner residue or soil residue on parts after cleaning
Sta-Sol ESS-160 - No cleaner residue or soil residue on parts after cleaning, however, it took a while for the parts to completely dry
Liquinox - Cleaner residue and soil residue remained on parts after cleaning. Cleaner will need a rinse step going forward with testing.
Dowanol PnBGE, Metalnox 6386, and Sta-Sol ESS 160 were the most effective at removing J2 soil from titanium parts using heated ultrasonics.
