Trial Purpose:
Laboratory evaluations of alternative cleaning products
Date Run:
09/22/2003Experiment Procedure:
Basic cleaning performance testing was conducted using ASTM G122 as the bases for cleaning.
Six products were used at full strength, heated to 120 F on a hot plate. Eighteen preweighed coupons were coated with CRC Industries Multipurpose Super White Grease (64741-96-4, 7620-77-1, 1314-13-2, 57885-77-3, 13463-67-7) and allowed to dry for three days and reweighed. Three coupons were cleaned in each solution for 5 minutes using stir-bar-agitation, rinsed in a tap water bath for 15 seconds at 120 F and dried using air blow off for 30 seconds at 68 F. Coupons were allowed to dry overnight and then reweighed a final time. Efficiencies were calculated.
Note: Bio T Foam Plus was sprayed onto coupons at room temperature and allowed to sit for 5 minutes. The cleaner was then rinsed off.
Trial Results:
None of the cleaners removed over 85% of the grease. One product was partially successful, removing just over 70%.
Success Rating:
Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.Conclusion:
No cleaners were successful in removing the grease within five minutes.
