To remove oil from painted steel using immersion 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 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.
|Cleaner||Initial Wt.||Final Wt.||% Removed|
|Phosphoric Acid Cleaner #1||0.5959||0.1054||82.31|
Success Rating:Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.
No product removed more than 85% of the oil from stainless using immersion cleaning.
