Trial Purpose:
The purpose of this experiment was to determine the effectiveness of four selected cleaners in removing Vanishing Oil from TURI steel coupons using unheated immersion.
Date Run:
08/20/2020Experiment Procedure:
Pre-weighed steel coupons were contaminated with the vanishing oil provided by the client and placed on the bottom third of each coupon. Dirty weights were recorded before immersing the coupons, three per cleaner, for 15 minutes at room temperature. After 15 minutes, coupons were dried using the air gun and final weights were taken.

Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.Conclusion:
Sta Sol ESS 160 was the most effective cleaner removing an average of 98.96% of soil from steel coupons. Surface Cleanse 930 was the second most effective removing an average of 89.95%, however, vendor alerted the lab to not use 5% going forward. Any further testing will need to be at 2% or less.
