Trial Number 2

Client Number 153

Project Number 6

Trial Purpose:

To determine the efficacy of aqueous cleaners compared to water utilizing VCN equipment.

Date Run:

04/14/2023

Experiment Procedure:

Eighteen pre weighed stainless steel coupons were used, three per soil per cleaner.  Half of the coupons were soiled by swabbing the bottom third of the coupons with Production Soil, while the other half of the coupons were soiled with DTE Cutting Oil.  The dirty weights of all coupons were then recorded.  The coupons were then subjected to a one-minute heated cycle at 140 degrees F in the VCN using water, Alcojet 1% concentration, and LF2100 1% concentration.  The coupons were then removed and left to air dry overnight.  The next day the clean weights of the coupons were recorded.

Success Rating:

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

Conclusion:

Water, Alcojet 1% concentration, and LF2100 1% concentration are highly effective in removing both soils from stainless steel utilizing VCN methods.
