Trial Number 2

Trial Purpose:

To evaluate the effectiveness of solvent and aqueous based cleaners on the removal of oil by heated immersion on aluminum and ceramic coupons.

Date Run:

01/31/2020

Experiment Procedure:

A set of 18 pre-weighed coupons, nine per substrate, were contaminated with either Canola Oil, Expoxidized Soybean Oil, or SAS-60E. Coupons were immersed into the cleaning solution heated to 140̊ F for one minute and then transferred into a deionized water bath also heated to 140̊ F for an additional minute. Afterwards, the coupons were dried with a heat gun, before final weights 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:

Aquaease PL 732 was effective on ceramic for canola oil and SAS-60E, and it was effective on aluminum with SAS-60E.
