Trial Purpose:
To evaluate the effectiveness of various cleaners in removing Marvel Mystery Oil from aluminum.
Date Run:
09/07/2016Experiment Procedure:
Four cleaners were tested at room temperature on aluminum coupons to evaluate how Marvel Mystery oil soil was cleaned. Preweighed coupons were coated with each supplied soil using a hand held swab for each substrate and weighed a second time to determine the amount of soil added. Each cleaner was put in a beaker and three coupons were immersed into the solution for 5 minutes. The coupons were then stood upright to air dry for 15 minutes and then placed on a tray. There was no rinse. Once dry, final weights were recorded and efficiency was calculated for each coupon cleaned.

Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.Conclusion:
Ecolink Fluosolv CX, Ecolink Fluosolv NC, and DuPont Vertrel Sion efficiently removed #9 Marvel Mystery Oil on aluminum at room temperature using immersion. Honeywell Solstice PF cleaned least efficiently. DuPont Vertrel Sion cleaned most efficiently with an overall efficiency of 99.21%.
