Project Number 1



Summary: Ten trials were conducted by the SSL which resulted in the identification of several products that may be effective in the client’s cleaning practice. Several on-site visits were made during testing to facilitate the adoption of these alternatives. The latest round of testing evaluated the following products: Biodiesel; Soy Clear 1500; Ionox HC 2; Metalnox M6310; Shopmaster RC. At this time, cleaned parts were sent back to the client for inspection using microscopes following the client’s QA/QC procedures.

Test Objective: Find a new cleaner for station cleaning - replace mineral spirits

Problems with Current Method: Using stoddard solvent mineral spirits. Close to air emission thresholds.

Purpose of Cleaning: remove metal fines from inside machined parts and remove cutting oil and lubricants

Product Use: electronic equipment

Cleaning Chemicals: Mineral Spirits, nPB, Metalnox M6435

Trial Number Date Run Purpose Success Rating
0 01/29/08 To evaluate laboratory selected products for the removal of the supplied cutting oil and compare to current cleaning solvents. Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined. 
1 01/30/08 To evaluate additional products that were more closely comparable to the past solvent used for cleaning. Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined. 
2 01/31/08 To evaluate products on second supplied cutting fluid. Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined. 
3 02/22/08 To evaluate products on second supplied cutting fluid Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined. 
4 02/22/08 To evaluate possible alternatives for solvent cleaning of oil Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended. 
5 03/13/08 To evaluate possible alternatives for solvent cleaning of oil Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended. 
6 03/13/08 To evaluate products on second supplied cutting fluid Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended. 
7 04/02/08 To evaluate top cleaning products on client supplied parts for their inspection Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended. 
8 04/30/08 To evaluate new product on the two supplied cutting fluids. A follow up test, usually based on company input. 
9 04/30/08 To evaluate selected products on supplied parts using simulated cleaning process Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended. 
10 01/17/08 To find a product that would replace mineral spirits in their dip cleaning applications located at each machine Technology Transfer. 
11 03/28/08 To find a product that would replace mineral spirits in their dip cleaning applications located at each machine Technology Transfer.
