Trial Number 1

Trial Purpose:

To evaluate possible replacement cleaners for Trichloroethylene.

Date Run:


Experiment Procedure:

Four cleaners were selected by the client through the use of the lab’s database search performed previously by the client. Ten to 15 parts were suspended on wire and then immersed into the cleaners at room temperature. Parts were cleaned for two minutes without agitation. At the end of the cleaning, the parts were removed and were dried for 30 seconds using a Master Appliance Corp, Hot-air gun model HG-301A at ambient conditions. Parts were observed at two different intervals for cleanliness. The first was at the one-minute mark and the other was after parts were dry. These parts were then returned to the client for inspection.

SUBSTRATE MATERIAL: Metal Parts - Carbon Steel, Stainless Steel
CONTAMINANTS: Metal Preserving Oil & Quenching Oil

Trial Results:

All four cleaners required less than the two minutes for cleaning.  Cleaning was actually completed in less than one minute.  A residue was on the parts from all the cleaners except D-Greeze 500.  There was no oil remaining on the parts.  Table 1 lists the observations made during the cleaning trial.

Cleaner Minimum Time  Oil Remaining Cleaner Residue
Methyl Ester 1 minute NO YES
D-Greeze 500 < 1 minute NO NO
Inproclean 4000 T 1 minute NO YES
Vortex < 1minute NO YES

Success Rating:

Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.


All four cleaners were effective in removing the oils from the parts at room temperature in under one minute.  The residues left behind could be removed if the parts were briefly rinsed.
