Trial #1
To evaluate the effectiveness of three low foam cleaners at removing canola oil, expoxidized soybean oil, and SAS-60E from aluminum and ceramic coupons.
Fifty-four pre-weighed coupons, eighteen for each cleaner, were soiled with Canola Oil, Soybean Oil, and SAS 60E using a clean swab. Each set of coupons was immersed in a 250mL beaker with the diluted cleaners for one minute at the vendor recommended temperature. Coupons were then transferred to a (140F) heated rinse for one minute before getting an additional one-minute dry with an air gun. Observations were made and final weights were recorded.

LF2100 and Aquavantage 3800 GD had lesser overall averages due to their lack of performance on the expoxidized soybean oil. SC Aircraft & Metal Cleaners had more consistent results with all of the substrates and soils.
SC Aircraft & Metal cleaner yielded the best results in removing the three tested soils. Although the acquired results don’t show 100% removal, adding high-pressure agitation will likely lead to even higher overall averages than shown for all of the cleaners tested.
