Unheated immersion, heated immersion at 100°F, heated immersion at 120°F, and heated immersion at 120°F with agitation were all conducted throughout trial testing. The following are the ideal cleaners and their suggested method: Metalnox 6386 100% concentration unheated immersion for 15 minutes. Dimethyl Glutarate 100% concentration heated immersion with a stir bar for agitation at 120°F for 30 minutes. SC Aircraft & Metal 20% concentration heated immersion with a stir bar for agitation at 120°F for 30 minutes followed by a 30 second deionized water rinse at 120°F. All parts are dried with a heat gun.

*Bold numbers excluded from average calculations; too little soil was applied to these coupons, and do not represent cleaner performance. Soil was most likely removed quickly then the substrate was damaged due to overexposure to solvent.*

Trial 7 Parts Testing

Cleaner Observations
Metalnox 6386 Post Clean & Dry: Appears to be effective, no oil residue visible
Smart Solve 605 May not have had enough solution for accurate testing. Post Clean: Appeared to be a residue which disappeared with drying.
Dimethyl Glutarate Post Clean & Dry: Appears to be effective, no oil residue visible
SC Aircraft & Metal During the cleaning process: oil droplets forming and falling into solution. Solution became foggy, indicating removal of soil occurring. Post Clean: Appeared to be a residue that disappeared with drying. 

*Smart Solve 605 was removed from the recommendation list due to difficulties trying to contact the vendor for several months*

Unheated immersion for 15 minutes with Metalnox 6386 at 100% concentration, Heated Immersion at 120°F with a stir bar for agitation for 30 minutes with Dimethyl Glutarate at 100% concentration, or Heated Immersion at 120°F with a stir bar for agitation for 30 minutes with SC Aircraft & Metal at 20% concentration, followed by a 30 second deionized water rinse at 120°F, are all effective potential alternative cleaning methods.
