Trial Number 7

Trial Purpose:

To evaluate top cleaning products on client supplied parts for their inspection

Date Run:


Experiment Procedure:

Four of the top products previously used in testing to clean the two client supplied soils were chosen to clean client supplied parts with. All four cleaners had a removal efficiency of well over 99% for both the Trimsol and the Hard Cut. The parts were taken out of the client supplied bags, sectioned in to 4 groups so all 8 types of parts would be cleaned in each cleaner.  Each cleaner was put in a bowl and a metal mesh basket was used to dunk and swirl the parts in the solutions. The parts were then put on a tray and when done were bagged for transport to the client. There was no rinse or drying involved. The process was done to as closely replicate the process used on site as possible.

Trial Results:

All four products removed oils from the parts and could be seen in the bowls of cleaners. Some oil or residual solvent was seen on the plastic when parts were put in the bag. This may not be an issue since parts receive a second cleaning either by degreaser or aqueous washer later in the process. Metal fine removal seemed very important at this step.

Success Rating:

Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended.


The client supplied parts will be brought back to the client for QA/QC inspection to see if any of the cleaners can be used as a substitute to their current cleaning process.
