Trial Purpose:
Laboratory evaluations of alternative cleaning products
Date Run:
09/22/2005Experiment Procedure:
Basic cleaning performance testing was conducted using ASTM G122 as the bases for cleaning.
Eight products were evaluated for the removal of C-Eblis cutting oil from aluminum coupons using immersion cleaning. The products were diluted to 5% using DI water in 600 ml beakers. Water was also evaluated as a control. Twenty-seven preweighed aluminum coupons were coated with the oil using a handheld swab. Coupons were weighed again to determine the amount of oil added. Three coupons were cleaned in each solution for 5 minutes using stir-bar agitation at room temperature. Coupons were rinsed in a tap water bath for 15 seconds at room temperature and rinsed for 2 minutes using a Master Appliance Heat Gun at 300 F. Final weights were measured and efficiencies were calculated.

Success Rating:
Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.Conclusion:
No product removed over 85% of the oil under the conditions tested.
