Trial Purpose:
To evaluate alternative cleaners on second supplied contaminant.
Date Run:
05/16/2007Experiment Procedure:
Six products from the previous trial were selected and used at full strength. The cleaning solutions were all heated to 130 F on a hot plate.
Eighteen preweighed alloy coupons were coated with the second supplied lubricant and weighed a second time to determine the amount of contaminant added to each coupon. Three coupons were immersed into each solution and cleaned for 5 minutes using stir-bar agitation. Coupons were rinsed in room temperature tap water for 15 seconds and air dried using compressed dry air for 30 seconds. A final weight was recorded, and efficiencies were calculated for each coupon cleaned.
Trial Results:
Five of the six products removed over 95% of the lubricant. Three of these removed over 99%. The table below lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.

Success Rating:
Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended.Conclusion:
The five products that removed over 95% will be tested on the third supplied contaminant under the same conditions.
