Trial Number 484

Trial Purpose:

To remove oil from painted steel surface

Date Run:

03/23/2009

Experiment Procedure:

Basic cleaning performance testing was conducted using ASTM G122 as the bases for cleaning. 

Products were selected based on the compatibility of substrate and for removal of the contaminant. Ten percent concentrations were used and heated the samples at 130F. The coupons were immersed in a product for 5 minutes, rinsed in tap water at 120 F and dried using compressed air at room temperature. Coupons were coated with the oil contaminant using a handheld swab and allowed to dry for 120 minutes at room temperature. The contaminated coupons were weighed again to determine the amount of soil added. After cleaning process, the final weights were recorded, efficiencies were calculated and recorded.

Success Rating:

Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.

Conclusion:

One product removed more than 85% of the oil (92.18%) from stainless steel using immersion cleaning.
